Q. 2

# Name the physical quantity which is considered to be a measure of the quantity of motion of a body.

Answer :

Momentum is considered to be a measure of the quantity of motion of a body. It is the product of the mass and velocity of an object, quantified in kilogram-meters per second. It is dimensionally equivalent to impulse, the product of force and time, quantified in Newton - seconds.
