Thus, a greater impulse is exerted on an object if it rebounds after a collision.

An object might rebound from a wall, or stick to it without rebounding after striking it.
In which situation will the wall exert greater impulse? Try to look at example below:

Both formulae can be used to solve numerical problems.
Both are vector quantities.

When a tennis racket hits an oncoming tennis ball, the tennis racket delivers a large force that acts on the ball for a short time t. The ball bounces off in the opposite direction. Again, there is a change in momentum.

The change in momentum is due to the force F acting on the object for a time T.

When a player kicks a football, his boot is in contact with the ball for a time t.

During the time, t, an average force F acts on the ball which makes the ball fly off with a momentum.

Thus, the force F, acting for a period of time t, produces a change in momentum to the ball, since the ball with a mass of m acquires velocity v after the time t.
