When a ball is bounced, a number of energy conversions occur. So when it hits you, it is going to hurt the least. Prepare to be seduced and get addicted to one of our most popular games. In the arcade classic of bouncing balls, your goal is to form groups of 3 or more balls of the same color so that they can be destroyed. The loss is usually described using coefficient of restitution. Department of physics, saint marys college of ca, 1928 st. Agood tennis player knows instinctively how hard to hit a ball and at what angle to get the ball over the net and into the. The simple physics of soccer the simple physics of soccer everyone knows that kicking a soccer ball causes it to roll across the grass.

A pdf version of this file but without the movies can be downloaded here.
The successes of quantum mechanics have been extraordinary. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape. Investigating the relationship between the drop height and. The wiffle ball would be the best to use for dodge ball because it has the least amount of momentum.

The tennis ball would be the best for bowling because it is the heaviest and will therefore have more momentum than the other balls moving at the same speed. Kicking a ball may seem simple, but physicists spent years trying to figure out why objects move the way they do. The phrase quantum jump or quantum leap is now in common usage, and incorrectly too. When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity.
