Impulse and Impulse Force

Calculate impulse, force, momentum change, and resulting velocity based on Newton's Second Law of Motion. Impulse forces act for a very short time and the impulse equals the change of momentum.

Impulse and Impulse Force

Forces acting for a very short time are called impulse forces. According to Newton's Second Law of Motion:

F = dM / dt

Where:

  • F = applied force (N)
  • dM = change of momentum (kg m/s)
  • dt = time taken (s)

The impulse I = F × dt = dM (change in momentum)

Momentum M = m × v, where m is mass (kg) and v is velocity (m/s)
