what is force applied over a period of time called

What happens when force is applied over time?

Force applied over time creates an impulse, a change in momentum. Impulse is defined in classical mechanics as a force multiplied by the amount of time it acts over. In calculus terms, the impulse can be calculated as the integral of force with respect to time. The symbol for impulse is J or Imp.

What is impulse of force?

Impulse of Force . The product of average force and the time in which it is exerted is the impulse of force. It is equal to the change of momentum of an object that isn't changing mass. This is a useful concept when you are studying impact forces. If you increase the time over which the change of force happens, the impact force also decreases.

What is the effect of time on impact force?

This is a useful concept when you are studying impact forces. If you increase the time over which the change of force happens, the impact force also decreases. This is used in mechanical design for safety, and it is useful in sports applications as well.
