- In this equation, J is impulse.
- Impulse - the product of force and the time the force is applied for.
- The units of impulse are units of force times units of time.
- The Most commonly used unit is the Newton second (N.s).
- Impulse is a vector in the direction of the net force.
- The equation for impulse given above is used under two conditions.
- Force remains constant.
- Average force is used if force is not constant.
