Rubber Sheet Bowling Ball And Tennis Ball Experiment

General relativity requires a curvature of space time not just space.

Rubber sheet bowling ball and tennis ball experiment. As a continuation of the theme of potential and kinetic energy this lesson introduces the concepts of momentum elastic and inelastic collisions. Bouncing ball experiment 3 the experiment will investigate the bounce efficiency of a tennis ball when dropped from different heights. The bowling ball has a greater mass so there s more stuff for gravity to act on. In that sense gravity is pulling on it more.

Newton s third law of motion for every action there is a reaction that is equal in magnitude and opposite in direction. In the classic classroom rubber sheet demonstration the marble rolls toward the bowling ball because the earth s gravity causes it to roll down hill. Kick a tennis ball and a bowling ball with the same amount of force the heavy bowling ball is going to move slower and go a shorter distance than the tennis ball a heavier object requires more force to set it in motion. After it has been dropped the tennis ball bounces back somewhat according to its unique drop height.

Describe the path of a golf ball when it just reaches the inside edge of the dip. At the drop height the tennis ball has gravitational potential energy which is then changed into kinetic energy as it tumbles to the ground kajiyama 2019.

Many sports and games such as baseball and ping pong illustrate the ideas of momentum and collisions. You can calculate this gravitational force as the product of the mass m and the gravitational field g. The bowling ball has a greater mass so it also has a greater gravitational force. Imagine a perfectly flat big rubber sheet that has a bowling ball in the center of it so it creates a slope.

It would follow a curved path. A used ball is generally softer than a new ball since ball stiffness depends on the wall thickness and the amount of air inside the ball. If the cloth cover wears down to say 2 mm thickness the ball will become softer. But it still doesn t fall any faster.

This is nothing at all like the way general relativity works.
