Answer:
We have seen quantities like velocity, acceleration, mass etc. and know what they signify. Now we will define a quantity known as momentum which is mathematically represented as:
P = mv
which is the amount of motion a body possess. As it is a product of mass and velocity so like velocity it is also a vector quantity. Its unit is Kg m s-1. Now we will relate the kinetic energy of a body with its linear momentum.
P = mv
