What is the bouncing ball experiment?

Bouncing Ball Experiment. Bouncing Ball Experiment. Determine how high the ball rebounds on its first bounce. To be consistent, again measure to the bottom of the ball. One group member should carefully release the ball and others should determine the height of the rebound.

What is the hypothesis of a bouncy ball?

The hypothesis states that if the height from which a bouncy ball is dropped is raised in increments of 20cm, respectively, from 20cm-200cm, then the bouncy ball dropped from 200cm will exhibit a greater rebound percentage.

What is the independent variable in the bouncing ball experiment?

Because we can drop the ball from any height we choose, the drop height is called the independent variable. But since the rebound height depends on the drop height, the rebound height is called the dependent variable.

How does the surface affect the bounce of a ball?

A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up. A soft surface, like grass or carpet, absorbs more energy from the fall, so there’s less left to push the ball back up, and it bounces pretty badly.

How Does height affect the bounce of a ball?

If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.

What happens to energy when a ball bounces?

Bouncing Back: Elastic potential energy is what causes a ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up.

What factors affect the energy of a ball?

The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to the kinetic energy.

What factors affect the efficiency of a bouncing ball?

Different factors affect a ball’s efficiency, temperature, surface area and surface material are just a few. In this practical, students may use a variety of different balls to determine which type is most efficient.

What factors affect bounce of ball?

The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.

What makes a ball bounce more?

When the ball hits the ground, all that kinetic energy has to go somewhere. A lot of it goes back into the ball, giving it more force to pop back up into the air—so the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!
