| Words | Definitions |
|---|---|
| Displacement | Difference between |
| Speed | A measure of distance an object travels in given amount of time |
| Velocity | The speed and directions of a moving object |
| Vector | The quantity that has both magnitude and direction |
| Reference Point | Starting point you use to describe the location |
| Position | The distance and direction from a reference point |
| Motion | The process of changing direction |
| Acceleration | Is a measure of change in velocity during a period of time |
| Force | A push or pull on an object |
| Contact Force | Is a push or a pull on one object by another that is touching it |
| Newton's 2nd Law | The acceleration of an object equals the net Force on the object divided by the object's mass. |
| Friction | Is a force that resists the sliding motion of two surfaces |
| Free-Body Diagram | A free body diagram |
| Net Force | iIs the sum of all the forces acting on and object |
| Newton's First Law | States that an object in motion will stay in motion, and an object at rest will stay at rest unless acted on by a force. |
| Inertia | To resist any change in motion |
| Noncontact Force | A force that one object can apply to another object without touching it. |
| Gravity | A attractive force that exists between all objects that have mass. |
| Field | A region of space that has a physical quantity (such as a force)at every point. |
| Weight | The gravitational force exerted on an object |
| Newton's 3rd Law | When an object applies a force on another object, the second object applies a force of the Same strength on the first object but force is in the opposite direction |
| Force Pair | The forces two objects apply to each other. |
| Normal Force | The force that pushes perpendicular to the object's surface |
| Elastic Collision | When colliding objects bounce off each other. |
| Inelastic Collision | When colliding objects stick to each other |
