Y9 sci conservation of energy tennis ball exp

How many lessons of class time do you have to work on the experiment and report?

• 1

• 2

• 3

• 4

What is the experiment about?

• Dropping a tennis ball and measuring how many times it bounces

• Dropping different types of balls and measuring bounce height and GPE

• Dropping a tennis ball from different heights and measuring bounce height and GPE

• Throwing a ball and measuring the distance

Energy stored because of gravity is called:

• Gravitational Potential Energy

• Kinetic Energy

• Mechanical Advantage

• Chemical Energy

The formula for calculating GPE is

• m x h

• m x g

• m x g x h

• m x v

What is the "aim" for this experiment?

• To determine the relationship between the gravitational potential energy and kinetic energy.

• To determine the relationship between work energy and rebound height of an object.

• To determine the relationship between the kinetic energy and rebound height of an object

• To determine the relationship between the gravitational potential energy and rebound height of an object.

What materials do you need for this experiment? Choose more than 1!

• Tennis ball

• 1 metre ruler

• 1 roll of masking tape (height marker)

• 1 set of weighing scales

• Different types of balls

Reorder the following steps in the procedure from first to last

• A tennis ball is dropped from a height of 120 cm. Use the ruler to measure the rebound height

• Drop height and rebound height is recorded.

• Mass of the tennis ball is recorded using weighing scales.

• Step 1 to 3 is repeated for drop heights of: 1.00 m, 0.80 m, 0.60 m and 0.40 m.

• Step 1 is repeated for two more times from the same drop height.
