Quick Practice - Try a Few Questions First Pick a chapter below, answer a few questions instantly, then jump to the full set list for more. Q1.The SI unit of length is the: Answer: (b) Metre. The metre is the SI base unit used to measure length.
Q2.Which of the following is a fundamental (base) quantity in the SI system? Mass is one of the seven base quantities in the SI system, unlike speed, force or area, which are all derived. That makes (c) Mass the correct choice.
Q3.The number of significant figures in the measurement 0.00420 is: The correct answer is (b) 3 — in 0.00420, the leading zeros are not significant, but the digits 4, 2 and the trailing 0 after the decimal point are counted.
Q4.Dimensional analysis is mainly used to: (b) Check the consistency of an equation is correct. Dimensional analysis compares the dimensions on both sides of an equation to verify that it is physically meaningful.
Q5.The dimensional formula of force is: Since force equals mass times acceleration, and acceleration has the dimensions [L T⁻²], multiplying by mass [M] gives the answer, (b) [M L T⁻²].
Q1.Displacement is a: Displacement has both a magnitude and a specific direction, which is what separates it from distance. That makes (b) Vector quantity the correct choice.
Q2.The area under a velocity-time graph gives: The correct answer is (b) Displacement — the region enclosed between the velocity-time graph and the time axis represents the distance covered, or displacement if direction is considered.
Q3.If a body moves with uniform velocity, its acceleration is: (c) Zero is correct. Uniform velocity means the velocity is not changing at all, and acceleration is simply the rate of change of velocity.
Q4.The slope of a position-time graph represents: Since velocity is defined as the rate of change of position with time, and slope measures exactly that rate on a graph, the answer is (b) Velocity.
Q5.A body starting from rest with uniform acceleration a covers a distance s in time t. Which relation is correct? Answer: (a) s = ut + ½at². This is the standard second equation of motion, applicable whether the body starts from rest or with some initial velocity u.
Q1.A scalar quantity has: The correct answer is (b) Only magnitude — a scalar quantity is fully described by a single numerical value with a unit, with no direction attached.
Q2.The resultant of two vectors is maximum when the angle between them is: (a) 0° is correct. When two vectors point in exactly the same direction, their magnitudes add directly to give the largest possible resultant.
Q3.Projectile motion is an example of motion in: Since a projectile moves simultaneously along both a horizontal and a vertical direction, the answer is (b) Two dimensions.
Q4.The horizontal range of a projectile is maximum when the angle of projection is: Answer: (b) 45°. At this angle, the horizontal and vertical components of the initial velocity are balanced in a way that maximises the range.

Q4.The SI unit of force is the: Force is measured in the unit named after the scientist who formulated the laws of motion. That makes (c) Newton the correct choice.
Q5.Friction acting on a body in motion is generally: The correct answer is (b) Opposite to the direction of motion — friction always acts to resist the relative motion between two surfaces in contact.
Q1.Work done is defined as the product of force and: Since work is done only when a force causes movement, and only the component of force along that movement counts, the answer is (b) Displacement in the direction of force.
Q2.The SI unit of energy is the: Answer: (c) Joule. This is the SI unit for all forms of energy, including kinetic, potential and thermal energy.
Q3.Kinetic energy of a body is given by: Kinetic energy depends on both the mass of a body and the square of its speed. That makes (b) ½mv² the correct choice.
Q4.Power is defined as the rate of doing: The correct answer is (b) Work — power specifically measures how quickly work is being done or energy is being transferred.
Q5.According to the work-energy theorem, the work done by the net force on a body equals the change in its: (b) Kinetic energy is correct. The work-energy theorem directly links the net work done on an object to the resulting change in its kinetic energy.
Q1.The centre of mass of a uniform rod lies at: Answer: (b) The midpoint of the rod. For any object with uniform density and symmetric shape, the centre of mass lies at its geometric centre.
Q2.Torque is the rotational analogue of: Just as force causes linear acceleration, torque plays the equivalent role in producing rotational acceleration. That makes (b) Force the correct choice.
Q3.The moment of inertia of a body depends on its: The correct answer is (a) Mass and its distribution about the axis — two objects of equal mass can have very different moments of inertia depending on how that mass is spread out from the axis of rotation.
Q4.Angular momentum is conserved when the net external: (b) Torque is zero is correct. Angular momentum stays constant over time only when there is no net external torque acting on the system.
Q5.For a rigid body in equilibrium, the vector sum of all external torques about any point must be: Since a rigid body in rotational equilibrium must have no tendency to start spinning in any direction, the answer is (b) Zero.
Q1.According to Newton's law of gravitation, the gravitational force between two masses is: Newton's law of gravitation describes how the attractive force grows stronger as either mass increases. That makes (a) Directly proportional to the product of their masses the correct choice.
Q2.The value of acceleration due to gravity on the surface of the Earth is approximately: The correct answer is (c) 9.8 m/s² — this is the standard value used for acceleration due to gravity near the Earth's surface.
Q3.The escape velocity of a body from Earth's surface is approximately: (c) 11.2 km/s is correct. This is the minimum speed an object needs to permanently break free of Earth's gravitational pull without further propulsion.
Q4.A satellite orbiting close to the Earth in a circular orbit experiences a centripetal force provided by: Since a satellite in circular orbit needs a continuous inward force to keep curving around the Earth, and nothing else is available in space, the answer is (b) Earth's gravitational pull.
Q5.According to Kepler's third law, the square of the orbital period of a planet is proportional to: Answer: (b) The cube of the semi-major axis of its orbit. This proportionality is exactly what Kepler's third law describes for planetary motion.
Q1.Stress is defined as: The correct answer is (a) Force per unit area — stress measures how much internal force a material experiences relative to its cross-sectional area.
Q2.Strain is defined as: (b) Change in dimension divided by the original dimension is correct. Strain is a ratio, and therefore has no units of its own.
Q3.Hooke's law states that, within the elastic limit, stress is: Since Hooke's law describes a direct, linear relationship between stress and strain within the elastic limit, the answer is (b) Directly proportional to strain.
Q4.Young's modulus is a measure of a material's resistance to: Answer: (c) Longitudinal (tensile or compressive) deformation. Young's modulus specifically quantifies how a material stretches or compresses along the direction of an applied force.
Q5.The SI unit of stress is the same as that of: Stress and pressure are both defined as a force acting over an area, which is why they share the same formula and unit. That makes (b) Pressure the correct choice.
Q1.Pressure exerted by a fluid at rest acts: (c) Equally in all directions is correct. A fluid at rest exerts pressure uniformly at any given point, regardless of the orientation of the surface it touches.
Q2.According to Pascal's law, pressure applied to an enclosed fluid is transmitted: Since Pascal's law describes how pressure change spreads through an enclosed fluid without loss, the answer is (b) Equally in all directions throughout the fluid.
Q3.The buoyant force on a submerged object equals the weight of the: Answer: (b) Fluid displaced by the object. This is Archimedes' principle, which explains why objects feel lighter when submerged in a liquid.
Q4.According to Bernoulli's principle, as the speed of a fluid increases, its pressure: Bernoulli's principle links a fluid's speed and pressure in an inverse relationship along a streamline. That makes (b) Decreases the correct choice.
Q5.Viscosity is a measure of a fluid's resistance to: The correct answer is (b) Flow — viscosity essentially describes the internal friction that resists a fluid's ability to flow smoothly.
Q1.The SI unit of temperature is the: Since the Kelvin scale is the SI base unit built specifically for absolute temperature measurement, the answer is (c) Kelvin.
Q2.Heat is a form of: Answer: (b) Energy. Heat represents energy transferred between objects due to a temperature difference between them.
Q3.The process by which heat transfers through a medium without the actual movement of particles is called: Conduction relies purely on energy passing between adjacent, vibrating particles rather than the particles themselves relocating. That makes (b) Conduction the correct choice.
Q4.When a substance changes from liquid to gas at constant temperature, the heat absorbed is called: The correct answer is (b) Latent heat — this is the energy absorbed or released during a phase change, without any accompanying change in temperature.
Q5.The zeroth law of thermodynamics is related to the concept of: (b) Thermal equilibrium is correct. The zeroth law establishes that if two systems are each in equilibrium with a third, they must be in equilibrium with each other.
Q1.The first law of thermodynamics is essentially a statement of the conservation of: Answer: (b) Energy. The first law of thermodynamics is essentially an extension of the principle of energy conservation to heat and work.
Q2.A thermodynamic process carried out at constant temperature is called: An isothermal process is specifically defined by the condition that temperature does not change throughout. That makes (c) Isothermal the correct choice.
Q3.In an adiabatic process, there is no exchange of: The correct answer is (b) Heat with the surroundings — an adiabatic process is defined by the complete absence of heat transfer into or out of the system.
Q4.According to the second law of thermodynamics, heat flows spontaneously from: (b) A hotter body to a colder body is correct. This directionality of spontaneous heat flow is a central idea behind the second law of thermodynamics.
Q5.A Carnot engine's efficiency depends on the temperatures of its: Since a Carnot engine's theoretical efficiency is calculated directly from the temperatures of the heat source and heat sink it operates between, the answer is (b) Source and sink.
Q1.The kinetic theory of gases assumes that gas molecules are in a state of: The kinetic theory pictures gas molecules as constantly moving and colliding in unpredictable directions. That makes (b) Constant, random motion the correct choice.
Q2.According to the kinetic theory, the pressure exerted by a gas is due to: The correct answer is (b) Collisions of molecules with the walls of the container — the theory explains gas pressure as the cumulative effect of countless molecular impacts.
Q3.The average kinetic energy of gas molecules is directly proportional to the: (c) Absolute temperature of the gas is correct. This direct proportionality between average kinetic energy and temperature is one of the central results of kinetic theory.
Q4.An ideal gas is one that obeys the: Since an ideal gas is essentially defined as one whose behaviour matches the ideal gas equation perfectly under all conditions, the answer is (b) Ideal gas equation exactly under all conditions.
Q5.The degrees of freedom of a monoatomic gas molecule is: Answer: (b) 3. A monoatomic molecule can only move along the three independent directions of space, giving it three translational degrees of freedom.
Q1.A motion that repeats itself at regular intervals of time is called: The correct answer is (b) Periodic motion — this term specifically describes motion that repeats identically after a fixed interval of time.
Q2.In simple harmonic motion, the restoring force is always directed: (b) Towards the mean position is correct. This restoring force pulling the object back toward equilibrium is what defines simple harmonic motion in the first place.
Q3.The time period of a simple pendulum depends on its: Since the time period of a simple pendulum is determined by how long it is and how strong gravity is at that location, the answer is (b) Length and acceleration due to gravity.
Q4.At the mean position of a simple harmonic oscillator, the velocity is: Answer: (b) Maximum. At the mean position, all the stored potential energy has converted into kinetic energy, giving the oscillator its highest speed.
Q5.At the extreme position of a simple harmonic oscillator, the acceleration is: At the extreme position, the restoring force pulling the oscillator back toward the centre is at its strongest. That makes (c) Maximum the correct choice.
Q1.A wave in which particles of the medium vibrate perpendicular to the direction of wave propagation is called: (b) Transverse wave is correct. In this type of wave, the particles of the medium oscillate at right angles to the direction the wave itself travels.
Q2.Sound waves are an example of: Since sound travels through air by compressing and rarefying the medium along the same direction the wave moves, the answer is (b) Longitudinal waves.
Q3.The speed of a wave is related to its wavelength and frequency by the formula: Answer: (b) v = λf. Wave speed is simply the product of wavelength and frequency, describing how far the wave travels in one complete cycle.
Q4.The phenomenon of superposition of two waves of slightly different frequencies producing a periodic variation in amplitude is called: Beats occur specifically when two waves of close but not identical frequencies combine, causing the amplitude to rise and fall periodically. That makes (b) Beats the correct choice.
Q5.The speed of sound in air is approximately: The correct answer is (b) 330 m/s — this is the approximate speed at which sound travels through air under normal atmospheric conditions.
