How does a collision demonstrate energy transfer?

• It creates new energy

• It transfers energy from one object to another

• It destroys energy

• It stops energy from moving

What are indicators of energy?

• Objects that do not move

• Sound, light, temperature change, and motion

• Only light and sound

• Only temperature change

Explain how energy is conserved in a system where a ball is dropped from a height.

• Energy is lost as the ball falls

• The potential energy is transformed into kinetic energy as the ball falls

• The ball gains energy as it falls

• Energy is created as the ball hits the ground

What happens to the energy when a generator is used?

• It is destroyed

• It is transformed from motion energy to electrical energy

• It remains unchanged

• It is transferred to another object

NGSS.MS-PS3-5

Describe a scenario where energy transfer occurs without a change in energy form.

• A light bulb lighting up

• A car engine running

• A book falling off a table

• A person pushing a swing

Which of the following is NOT an indicator of energy?

• Sound

• Light

• Color

• Temperature change

How does speed relate to energy in a moving object?

• Speed has no relation to energy

• The faster an object moves, the more energy it has

• The slower an object moves, the more energy it has

• Speed decreases energy
