What is potential energy?

Back

Potential energy is the energy that is stored in an object due to its position or state. It can be used later to do work.

Front

What is sound energy?

Back

Sound energy is produced when an object vibrates, creating waves that travel through air or other mediums.

When does a marble have the most potential energy on a ramp?

Back

A marble has the most potential energy at the top of the ramp, where it is highest above the ground.

Front

What is the ultimate source of energy for Earth?

Back

The ultimate source of energy is the sun, which provides light and heat.

Front

What causes sound?

Back

All sound is made by vibrations, which create sound waves.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is electromagnetic energy?

Back

Electromagnetic energy is a form of energy that travels in waves, such as light, radio waves, and X-rays.

Front

How can energy be transformed?

Back

Energy can be transformed from one form to another, such as potential energy converting to kinetic energy when an object falls.

Front

What is the relationship between energy and work?

Back

Work is done when energy is transferred from one object to another, allowing it to move or change.
