What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, chemical, and more.

What is sound energy?

Back

Sound energy is a type of energy produced by vibrating sound waves that require a medium (solid, liquid, or gas) to travel.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object. It is the energy associated with the motion and position of an object.

Front

What is thermal energy?

Back

Thermal energy, also known as heat energy, is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Where is potential energy highest on a roller coaster?

Back

Potential energy is highest at the top of a big hill on a roller coaster.

Front

What factors affect potential energy?

Back

Potential energy depends on mass and position (height) of an object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

What is an example of chemical energy?

Back

Chemical energy is stored in the bonds of chemical compounds, such as food, batteries, and fuels.
