Different Forms of Energy Quiz

What is energy, and how does it cause changes in objects?

• Energy is the ability to destroy objects.

• Energy is the ability to do work.

• Energy is the ability to stop objects from moving.

• Energy is the ability to remain stationary.

How does potential energy differ from kinetic energy?

• Potential energy causes motion, while kinetic energy stops motion.

• Potential energy changes into kinetic energy as it goes downward.

• Kinetic energy changes into potential energy as it goes upward.

• Kinetic energy is stored, while potential energy is motion.

What happens to the potential energy of a rollercoaster as it moves downward?

• It increases into gravitational potential energy.

• It transforms into sound energy.

• It changes into kinetic energy.

• It disappears completely.

What is mechanical energy made up of?

• Potential energy and kinetic energy.

• Sound energy and light energy.

• Gravitational energy and elastic energy.

• Chemical energy and thermal energy.

How does the speed of an object affect its kinetic energy?

• The faster an object moves, the greater its kinetic energy.

• The faster an object moves, the less kinetic energy it has.

• Kinetic energy is not affected by speed.

• Kinetic energy decreases as speed increases.

What is gravitational potential energy?

• Energy of motion.

• Stored energy of an object above the ground.

• Energy of a compressed spring.

• Chemical energy from food.

What is elastic potential energy?

• Energy from an object in motion.

• Energy stored in food.

• Energy stored in a rollercoaster.

• Energy of a stretched rubber band or compressed spring.

Where does the pole-vaulter get energy for her jump?

• From chemical potential energy stored in her body.

• From gravitational energy stored in the pole.

• From sound energy.

• From thermal energy.

How does sound energy travel?

• Through particles bumping into each other.

• By bending around objects.

• Through light waves.

• By chemical reactions.

What is the difference between pitch and volume?

• Pitch is how loud a sound is, and volume is its frequency.

• Pitch tells how high or low a sound is, and volume is its loudness.

• Pitch determines loudness, and volume determines speed.

• Pitch and volume are the same thing.
