What is impulse equal to?

Impulse is equal to the change in momentum of an object, which can be expressed mathematically as the product of force and the time duration over which the force acts. It is given by the equation ( J = F \Delta t ), where ( J ) is impulse, ( F ) is the average force, and ( \Delta t ) is the time interval. In terms of momentum, impulse can also be represented as ( J = \Delta p ), where ( \Delta p ) is the change in momentum.
