What is energy?

Back

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

What are the two main types of energy?

Back

The two main types of energy are kinetic energy (energy of motion) and potential energy (stored energy).

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and velocity of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has gravitational potential energy.

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, a metal spoon heating up in a bowl of hot soup.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cooler fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. An example is the heat from the sun warming the Earth.

What is a conductor?

Back

A conductor is a material that allows the flow of electric current or heat. Metals like copper and aluminum are good conductors.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current or heat. Examples include rubber, glass, and plastic.
