What you’ll learn

Define energy and tell the difference between kinetic, potential, and heat energy with examples.Energy is the power to make things happen. Moving things have kinetic energy, stored things have potential energy, and heat energy comes from fast-moving atoms and molecules.
Describe light and electrical energy, explain that energy changes form, and name renewable sources.Light and electrical energy power our world, and energy can change from one form to another without being created or destroyed. Sun, wind, and water are clean, renewable sources.

Questions this course answers

What do we call the energy of something that is moving?

Kinetic energy is the energy of motion, like a rolling ball or blowing wind.

A ball sitting at the top of a hill mostly has which kind of energy?

Potential energy is stored energy of position, ready to become motion when the ball rolls down.

What causes an object to feel hot?

Heat energy comes from atoms and molecules moving; the faster they move, the hotter it is.

What is Earth's biggest natural source of light energy?

The Sun gives Earth the light and warmth that living things need to survive.

In a lightbulb, electrical energy mainly changes into which form?

A lightbulb turns electrical energy into light energy plus a little heat.

Which of these is a renewable energy source from nature?

Wind, sunlight, and flowing water are renewable because nature keeps refilling them.
