Physics

The science that studies how the universe works, focusing on matter, energy, and the relationships between them.

Sound

A mechanical wave that propagates through a medium (air, water, or solids) as a result of disturbances or vibrations.

Heat

The transfer of thermal energy between objects due to a temperature difference (via conduction, convection, or radiation).

Friction

Gravity

A fundamental force of nature that attracts objects with mass toward each other; keeps us grounded and governs planetary motion.

Magnetism

A fundamental force associated with moving electric charges, causing attractions and repulsions between objects.

Inertia

The tendency of an object to resist changes in its state of motion.

Force

Any action that can change an object's velocity (speed or direction) or cause it to deform.

Newton's Third Law of Motion

For every action, there is an equal and opposite reaction.

Electricity

A power source for devices and systems, used for lighting, heating, cooling, refrigeration, and powering electronics.

Light

A form of electromagnetic radiation that can be detected by the human eye.

Atom
