Impulse

Impulse is the product of a force and the time interval over which it acts, equal to the change in momentum.

Formula

J = F * delta_t = delta_p

This is the impulse-momentum theorem.

计算示例

A bat exerts an average force of 100 N on a ball for 0.5 seconds.

  1. J = F * t
  2. J = 100 * 0.5
  3. J = 50 N·s
