Bundle 1 Scope 4 Kinetic Energy

A student creates a ramp by stacking four blocks and then leaning a meter stick against it. She releases four different balls from the same position on the ramp and calculates their speeds.

Based on the information in the table above, which ball would you predict to have the least kinetic energy when it reaches the end of the ramp?

• golf ball

• tennis ball

• baseball

• softball

A graph showing the kinetic energy of a 10 kg object at different speeds is provided.

Based on the information in the graph, we can predict that the kinetic energy of the object at 2 m/s would be–

• 12 Joules

• 20 Joules

• 38 Joules

• 44 Joules

Students conduct an experiment using a toy car with the mass of 10g, a toy car with the mass of 20g, and a toy car with the mass of 30g. The students want to test the cars on a ramp and measure how far the cars traveled. Evaluate the information and determine the question they are trying to test with this experiment.

• Does the height of the ramp influence the amount of potential energy?

• Does the map of the car influence the amount of kinetic energy?

• Does the amount of incline determine how far the car will travel?

• Does the amount of the object influence the amount of potential energy?

A graph showing the kinetic energy and mass of objects traveling at 10 m/s is shown.

In order for an object moving at 10 m/s to have a kinetic energy of 1800 Joules, the object must have a mass in the range of–

• 0-10 kg

• 10-20 kg

• 20-30 kg

• 30-40 kg

A graph showing the kinetic energy and speed of a moving object is provided.

Which of the following can be concluded from the graph?

• Kinetic energy only changes when speed changes.

• Speed is only related to the size of an object.

• Kinetic energy increases as speed increases.

• All moving objects have the same kinetic energy.
