What is energy?

 Energy is the ability to do work or cause change.

100

What is an example of potential energy?

 A rock at the top of a hill.

100

 What is energy transformation?

Energy changing from one form to another.


100

What is energy transfer?

 Energy moving from one object to another.

100

What is the law of conservation of energy?

Energy cannot be created or destroyed, only transformed.


200

 Name two forms of energy.

Kinetic and potential energy.


200

What is an example of kinetic energy?

 A moving car.

200

Give an example of chemical energy transforming into another form

Food converting to mechanical energy when we move.

200

Name one way energy transfers through collisions

By direct impact (e.g., a car crash).


200

Can energy be created or destroyed?

No, it can only change forms.

300

What is kinetic energy?

Energy of motion.

300

Describe the difference between potential and kinetic energy

Potential energy is stored energy; kinetic energy is energy in motion.

300

 Describe potential energy transforming into kinetic energy.

A ski jumper moving down a ramp.

300

Describe energy transfer through sound.

Sound energy travels through air as vibrations.

300

What is an example of chemical energy?

Food, body cells, batteries, or petroleum products.

400

What is electromagnetic radiation?

Waves that do not need a medium to travel through. 

400

 How does energy change in a bouncing ball?

It converts potential energy to kinetic energy and vice versa.


400

What happens when a lamp turns on?

 Electrical energy transforms into light and thermal energy.

400

What happens when a wrecking ball hits a wall?

 The ball's energy transfers to the wall, causing it to break.

400

Where is nuclear energy located?

In the nucleus or nuclei 

500

Explain nuclear fission and fusion.

Fission the nucleus splits and releases energy. Fusion small nuclei combine to form a larger nuclei.

500

What are three examples of kinetic energy?

 A flying bird, a rolling ball, a running person

500

 Explain how mechanical energy is generated.

It is generated through the motion of objects or machines.

500

 Explain how heat from the sun transfers energy.

Through radiation, warming the Earth.
