Scalars And Vectors Revision Notes for Full Course Scalars and Vectors

 

Scalars and Vectors
 
Scalar Quantities can be denoted by a number and a unit, i.e. Magnitude. Vector Quantities are denoted by magnitude and direction.
 
Tensor Quantities
 
Tensor Quantities are those quantities whose magnitude changes based upon the direction in which you measure it. (e.g. Moment of Inertia)
 
Types of Vectors
 
Equal Vectors: Vectors having same direction and magnitude.
 
Parallel Vectors: Vectors having same direction.
 
Anti-Parallel Vectors: Vectors having opposite directions.
 
Position Vector: Vector drawn from the origin to a point.
 
Zero Vector: Vector of magnitude zero.
 
Free Vector: Vector which can be moved through space, without changing its direction.
 
Triangle Law
 
If two vectors exist such that their directions are taken in order, then their resultant is equal to the third of the triangle formed; & the direction is from head of first to tail of second.

Parallelogram Law
The parallelogram law of Vectors states that if two vectors originate or meet at a common point,then their resultant is given by the diagonal of parallelogram formed.

Scalar Multiplication
 
Scalar multiplication refers to the multiplication of a vector with a number.
In Scalar Multiplication, the number is multiplied to all components of the vector. Thus, scalarmultiplication does not change the direction of the vector, it only affects the magnitude.
 
Resolution of Vectors
for co-ordinate system, we know that:
x = rcosθ y = rsinθ
for 3-d coordinate system, we resolve using direction cosines :
r = acosα + acosβ + acosγ

Scalar Product
a.b = abcosθ
Scalar Product gives us a Scalar result.
 
Vector Product
axb = absinθ
Vector product gives us a vector result.
 
Unit Vector
A unit vector has unit magnitude and any direction. If we divide a vector by its magnitude, we get an unit vector
