Forces in Motion
| Term | Definition |
|---|---|
| Terminal Velocity | The highest velocity achievable by a falling object. This is caused by wind resistance. |
| Free Fall | The motion of a body when only the force of gravity is acting on the body. The object falls without wind resistance. |
| Projectile Motion | The curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth. |
| Newton's First Law of Motion | An object at rest stays at rest, and an object in motion stays in motion unless acted on by an outside force. |
| Newton's Second Law of Motion | The acceleration of an object depends on the mass of the object and the amount of force applied. F = m x a (Force = mass x acceleration). |
| Newton's Third Law of Motion | For every action there is an equal but opposite reaction. |
| Inertia | The tendency of an object to resist changes in motion. Objects moving resist being stopped. Objects not moving resist movement. |
| Momentum | This is the quantity defined by mass x velocity. (m x v = ?) |
