Energy Types, Transfer, and Transformation

Front

What is radiation?

Back

Radiation is the transfer of energy through space by electromagnetic waves. It does not require a medium to travel through, and is how heat from the sun reaches the Earth.

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.

Where is potential energy greatest on a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster, where the gravitational pull is strongest.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer, less dense fluid rises while cooler, denser fluid sinks.

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.

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.

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance. It is related to temperature and the state of matter.

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.

What is kinetic energy?

Back

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

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.
