What is Impulse?

The Impulse applied to an object causes a change in the momentum of the object. Impulse is the product of force and time of impact.

J = Ft

where;

  • J is the impulse
  • F is the applied force
  • t is the time of impact

The increase in the time of impact increases the impulse experienced by the object, and a decrease in the time of impact causes a decrease in the impulse experienced by the object.

Thus, we can conclude that the foam decreases the time of impact because it cushions the effect of impact.
