| Term | Definition |
|---|---|
| acceleration | is a measure of the change in velocity a period of time |
| force | is a push or a pull on an object |
| contact force | is a push or a pull on one object that another object that is touching it |
| newton | states that by that objects will acceleration equation |
| friction | is a force that resisted the sliding motion of two surfaces |
| free body diagram | is a simple model to understand systems of object with any amount of applied forces |
| net force | is the sum of all the forces acting on an object |
| newton first law of motion | states that an object in motion will stay in motion and an object at rest will stay. |
| motion | the change in position of an object over time relative to a reference point |
| Displacement | is the difference between the initial or starting position and displacement is 40 m in front of her initial position |
| speed | is a measure of the distance an object travels in a given amount of time |
| Velocity | is the speed and direction of a moving object |
| Vector | is a quantity that has both magnitude and direction |
| Reference Point | a fixed place, object, or value used as a basis for measurement, comparison, or orientation |
| Position | the specific place, location, or arrangement of someone or something in space, a sequence, or a social structure |
| Inertia | the natural tendency of an object to resist changes in its state of motion |
| Newton's 3rd Law | states that when an object applies a force on another object |
| Force Pair | is the forces two objects apply to eath other |
| Normal Force | is the force you push on the wall the wall has a normal force that pushes perpendicular to the object surface |
| Elastic Collision | if object collide and stick together |
| Inelastic Collision | 2 objects collide and don't stick together |
| Non-contact Force | is a force that one object can apply to another object without touching it |
| Gravity | is an attractive force that exists between all objects |
| Field | is a region of space that has a physical quabtity such as a force |
| Weight | is the gravitational force exerted the object |
