Linear momentum of a body is the quantity of motion contained in the body.
It can also be measured in terms of the force required to stop the body in unit tim

Law of Conservation of Linear Momentum:
If no external force acts on a system (isolated), the total momentum of the system remains constant with ti
It is defined as the ratio of normal stress to longitudinal strain within limit of proportionality.Y=
Angular Momentum
The turning momentum of particle about the axis of rotation is called the angular momentum of the particle.
Formulas and Important Points
1. v = u+ at ... s=ut+(1/2)t2 ..... v2-u2 = 2as .....
The ratio of change in configuration to the original configuration is called strain.
Being the ratio of two like quantities, it has no dimensions and units.
# Linear magnification of a spherical mirror (m):
m = size of image (h2)/size of object (h1) = A’B’/AB
