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 rock at the top of a hill has gravitational potential energy.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, a metal spoon getting hot in a pot of boiling water.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). For example, warm air rising and cool air sinking.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. For example, heat from the sun reaching the Earth.

Front

What are conductors?

Back

Conductors are materials that allow heat and electricity to flow through them easily. Examples include metals like copper and aluminum.

Front

What are insulators?

Back

Insulators are materials that do not allow heat or electricity to flow through them easily. Examples include rubber, glass, and wood.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.
