What is energy?

Back

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

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 ball at the top of a hill has potential energy.

Front

What is gravitational energy?

Back

Gravitational energy is a type of potential energy that depends on an object's height above the ground. The higher the object, the more gravitational energy it has.

Front

What is electrical energy?

Back

Electrical energy is the energy of moving electrons. It powers devices like lights, computers, and appliances.

Front

What is heat energy?

Back

Heat energy, or thermal energy, is the energy that comes from the temperature of matter. It is the energy that causes substances to feel warm or hot.

Front

What is the source of energy for plants?

Back

Plants get their energy from sunlight through a process called photosynthesis.

Front

What is the role of batteries in electrical circuits?

Back

Batteries store chemical energy and convert it into electrical energy to power devices.

What is the importance of the tallest hill in a roller coaster?

Back

The tallest hill provides enough gravitational energy to allow the roller coaster to complete the ride.

Front

What is the difference between renewable and non-renewable energy?

Back

Renewable energy comes from sources that can be replenished, like solar and wind, while non-renewable energy comes from sources that can run out, like coal and oil.
