Understanding Squash Balls and Their Bounce

What is Max's initial understanding of squash?

• He thinks it's a type of swimming.

• He thinks it's similar to basketball.

• He believes it's a lot like tennis.

• He believes it's a form of running.

Why does Bjorn say the balls are not the same?

• They are different weights.

• They are different shapes.

• They are different sizes.

• They are made of different materials.

What happens to potential energy when a ball is dropped?

• It converts into kinetic energy.

• It remains as potential energy.

• It disappears completely.

• It turns into sound energy.

What is the main difference between elastic and inelastic materials?

• Elastic materials do not deform.

• Inelastic materials are lighter.

• Inelastic materials bounce higher.

• Elastic materials return to their original shape.

How do polymers affect the bounce of a ball?

• Tighter polymers increase bounce.

• Looser polymers increase bounce.

• Polymers have no effect on bounce.

• Polymers make the ball heavier.

What happens when polymers rub against each other?

• They produce light.

• They produce sound.

• They produce heat.

• They produce electricity.

How does temperature affect the polymers in a ball?

• Lower temperatures make polymers stretchier.

• Higher temperatures make polymers stiffer.

• Higher temperatures make polymers stretchier.

• Temperature has no effect on polymers.

What is a practical way to increase the temperature of a squash ball?

• Leave it in the sun.

• Place it in a refrigerator.

• Bounce it repeatedly.

• Soak it in water.

What did Max predict about the warmer ball?

• It would bounce lower.

• It would not bounce at all.

• It would bounce the highest.

• It would bounce the same as the colder ball.

What two factors determine a ball's bounce according to Max's summary?

• Shape and color.

• Size and weight.

• Material and temperature.

• Material and color.
