Definition: Thermal energy is produced when rising temperature causes atoms to move faster and collide.

Example: Chemical energy is demonstrated in fuel, food, and batteries.

Highlight: Electrical energy is considered a secondary form of energy, generated at power plants or in batteries.

Vocabulary: Nuclear energy is stored in atomic nuclei and released through fusion or fission.

Definition: Potential energy is the energy in matter due to its position or arrangement of parts.

Example: A ball's journey down a hill demonstrates both potential and kinetic energy transformations.

Highlight: The higher an object's position or the greater its mass, the more potential energy it possesses.

Vocabulary: Kinetic energy refers to the energy of objects in motion, increasing with speed.

Definition: The law of conservation of energy states that energy cannot be created or destroyed, only change forms.

Example: A toaster converting electrical energy to thermal energy demonstrates energy transformation.

Highlight: No energy transfer is 100% efficient, with some energy always converting to heat.

Quote: "Energy cannot be created or destroyed, only change forms."

Definition: Energy is the ability to do work or cause change.

Highlight: Energy can be moved between objects and transformed from one form to another.

Example: Mechanical energy examples include kicking a ball, riding a bike, and sound waves.

Vocabulary: Radiant energy refers to energy that can move through empty space or matter in wave form, including radio waves, microwaves, and various light forms.
