What is energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

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 gravitational potential energy.

Front

What happens to warm air compared to cold air?

Back

Warm air is lighter than cold air, causing it to rise, while cold air, being denser, sinks.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power devices like light bulbs in a circuit.

Front

What is the relationship between mass and energy?

Back

The more mass an object has, the more energy it has when in motion, as seen in the example of a heavy bike versus an empty bike.

Front

What types of energy does a toaster use?

Back

A toaster uses heat energy to toast bread, and it may also produce light and sound energy.

Front

What is the principle of conservation of energy?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between light energy and sound energy?

Back

Light energy is electromagnetic radiation that can be seen, while sound energy is produced by vibrating objects and travels through air or other mediums.
