What is energy?

Back

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

Front

What are the main forms of energy?

Back

The main forms of energy include: 1. Kinetic Energy 2. Potential Energy 3. Thermal Energy 4. Chemical Energy 5. Electrical Energy 6. Sound Energy 7. Nuclear Energy

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 potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a raised object has gravitational potential energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel. It is released during a chemical reaction.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to its temperature. It is often referred to as heat energy.

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.

What happens to energy when a roller coaster goes up a hill?

Back

As a roller coaster goes up a hill, kinetic energy is converted into gravitational potential energy.

Front

What happens to energy when a roller coaster goes down a hill?

Back

As a roller coaster goes down a hill, gravitational potential energy is converted back into kinetic energy.

Front

What is the energy transfer when eating food?

Back

When you eat food, chemical energy from the food is converted into kinetic energy for movement and other bodily functions.
