24-25 Energy Study Guide

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy an object has when it is at rest and has the potential to move.

Front

What is kinetic energy?

Back

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

Front

What is the law of conservation of energy?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It can cause energy to be transformed into thermal energy, resulting in heat.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other.

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 fluid 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 and can occur in a vacuum.

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 or absorbed during a chemical reaction.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices and appliances.
