Test Review: Potential and Kinetic Energy

If you kick a soccer ball and it is moving through the air towards the goal, what type of energy does the soccer ball have?

• chemical energy

• kinetic energy

• elastic energy

• magnetic energy

Which two variable affect the kinetic energy in a kicked soccer ball?

• height and speed

• mass and height

• mass and speed

• height and gravity

You conduct a lab with a bouncy ball, a marble, and a Styrofoam ball. You investigate the speed each one travels down a ramp. What are you investigating in the experiment?

• the slope of the ramp

• the distance traveled

• the mass of the ball

• the affect of gravity

Which part of the roller coaster has the most kinetic energy?

• A

• B

• C

• D

According to the picture, which person has the most kinetic energy?

• Person A

• Person B

• Person C

• KE is equal for all people

If all of the vehicles shown were to travel downhill, which vehicle would have the least amount of kinetic energy at the bottom of the hill?

• dump truck

• big rig

• race car

• all would have the same amount

According to the graph, what happens to kinetic energy as mass increases?

• when mass doubles, kinetic energy doubles

• as mass doubles, kinetic energy halves

• as mass doubles, kinetic energy quadruples

According to the graph, what is the relationship between speed and kinetic energy?

• there is no relationship

• as speed doubles, kinetic energy doubles

• as speed doubles, kinetic energy decreases

• as speed doubles, kinetic energy quadruples
