1. Which physical quantity is represented by the product of moment of inertia and angular Velocity?
 
2. Why is it more difficult to revolve a stone tied to a large string than a stone tied to a smaller string?
 
3. Explain why the speed of whirl wind in a tornado is alarmingly high? 
 
4. State the theorem of perpendicular axes for moment of inertia. 
 
5. Particle of mass 0.2Kg is moving in a circle of radius 1m with frequency 2/π S-1. Find its angular momentum.
 
6. Define radius of gyration. Write its SI unit and dimensional formula. 
 
7. Derive the relation between torque and angular momentum. 
 
8. Three balls of masses 1, 2 and 3Kg respectively are arranged at the corners of an equilateraltriangle of side 1m.What will be the M.I. of the system about an axis through the centroid and perpendicular to the plane of triangle?
 
9. Derive an expression for the rotational kinetic energy of a body. State the factors on which rotational kinetic energy of a body depends.
 
10. If the earth were suddenly contract to half of its present size, by how much would the day be decreased? Given moment of inertia of the earth = 2/5 MR2.
 
11. Define moment of inertia. Write its SI units and dimensional formula. State the factors on which moment of inertia of a body depends.
 
VALUE POINTS 
 
1. Angular momentum(L) 
 
2. Moment of inertia of a stone tied to longer string is more than the moment of inertia of a stone tied to a smaller string.
 
3. The inner layers of the whirl wind in a tornado are closer to the axis of rotation. It means, the moment of inertia of the air molecules of inner layers is small. Hence, according to the law of conservation of
angular momentum, the angular speed of the whirl wind In a tornado is very high.
 
4. The moment of inertia of a plane lamina about an axis perpendicular to its plane is equal to the sum of the moments of inertia of the lamina about any two mutually perpendicular axes in its plane and intersecting each other at the point where the perpendicular axis passes though it.
 
5. w = 4 rad s-1, v = rw =4 X 1 = 4ms-1, L = mvr L = 0.8Kgm2s-1
 
 
6. Definition
SI Unit is metre.
(M0L1T0)
 
7. Derivation: τ = d L/dt, 2M
8. I=(m1+m2+m3)r2=(1+2+3)×(1√3)2=2kgm2
 
9. Derivation: Ek = ½ Iw2
Rotational kinetic energy depends on the factors:
(i) Moment of inertia (ii) angular speed of the body.
 
10. from the principle of conservation of angular
momentum
I´ω´＝Iω
T1 = 6hr
Day will be decreased by (24hr – 6hr) = 18hr
 
11. Definition of M.I.
SI unit: Kgm2 ( M1L2T0)
Any two factors
