Everyone recognizes when a momentum collision happens between two cars, but it also happens in sports. In this picture, we see that after two football players collide with each other, one football player is going forward and pushing the other back. This is an example of two forces using momentum against each other. Whether it's because the football player, moving forward, has more mass or speed, he had momentum allowing him to push the other football player.

When you go to the gym and do a warm-up set on bench press, you're actually pushing up way lass than you normally do. Now, you may think that when it comes to who is exerting more force between you or the barbell, it you because it's not heavy. WRONG! In actuality, you and the barbell with weights are exerting the same amount of force, according to Newton's 3rd Law, which says the forces of two bodies on each other are always equal and are directed in opposite directions.

When two people who are most likely similar in weight are racing, they exert force for a certain distance. Therefore they produce work. One runner finishes first, so you would think that he did more work than the other runner. What is interesting is that they produced the same amount of work. It is power in fact that the faster runner exerted more in. When it comes to power, time becomes a factor. So, since the faster runner finished in less time, he exerted more power than the other runner.
