# Impulse (Velocity)

## Description

Impulse is the product of a force and the time, for which it acts. The impulse of a force acting for a given time interval is equal to the change in linear momentum produced over that interval. The impulse of an object, to which a resultant force is applied, may be expressed by the product of its mass (when the mass is constant) and the difference between the final velocity of the object at the end of the time interval, and the initial velocity of the object when the time interval begins.
