What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, when a hot pot is touched, heat transfers from the pot to the hand.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium, so it can occur in a vacuum, like sunlight reaching Earth.

Front

What is kinetic energy (KE)?

Back

Kinetic energy is the energy of an object due to its motion. The more mass and speed an object has, the more kinetic energy it possesses.

Front

What is potential energy?

Back

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

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with mass. If two objects are moving at the same speed, the one with more mass will have more kinetic energy.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another. For example, chemical energy in wood transforms into heat and light energy when burned.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released during a chemical reaction.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye. It is produced by the movement of photons.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.
