Question

Give the definition of IMPULSE.

Answer 1

Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time. So, with impulse, you can calculate the change in momentum, or you can use impulse to calculate the average impact force of a collision.

Answer 2

Impulse is defined as the product of force and time of action of force acting on a body. It is a vector quantity. Its direction is in the direction of momentum change.
