Terms | Definitions |
|---|---|
 Terminal Velocity | Constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity |
| Free Fall | Motion of a body when only the force of gravity is acting on the body |
| Projectile Motion | Curved path that an object follows when thrown, launched or otherwise projected near the surface of Earth |
| Newton's First Law | An object at rest remains at rest, an object in motion remains in motion at constant speed and in a straight line unless acted upon by an unbalanced force |
| Inertia | Tendency of all objects to resist any change in motion |
| Newton's Second Law of Motion | Acceleration of an object depends on the mass of the object and the amount of force applied |
| Newton's Third Law of Motion | Whenever one object exerts a force on a second object the second object exerts an equal and opposite force on the first |
| Momentum | Quantity defined as the product of the mass and velocity of an object |
