| Question | Answer |
|---|---|
| Acceleration | is a measure of the change in the velocity during a period of time |
| Force | is a push or pull object |
| contact | is a push or pull on one object |
| Newtons second law of motion | states that the acceleration of an object equals the net force on the object divided by the objects mass |
| Friction | is a force that resists the sliding motion of two surfaces that are touching. |
| free-body diagram | is a simple model to understand system of objects with any amount of applied |
| free-body diagram | is a simple model to understand systems of objeacts with any amount of applied |
| net force | is the sum of all the forces acting on an object |
| Newton's first law of motion | states thast an object in motion will stay in motion and an object at rest will stay at rest unless acted on by a force |
| Interia | to resitany change in motion |
| Force pair | is the forces two objects apply to each other. |
| Normal Force | is the force that pushes perpendicular to the objects surface |
| elastic colilision | when colliding objects bounce off each other is an elastic colilision |
| Non contact force | is a force that one object can apply to another object without touching it |
| Gravity | is attractive force that exists between all objects that have mass |
| field | is a region of space that has a physical quantity (such as force) at every point |
| weight | is the gravitational forceexcerted on an object |
| reference point | a basis or standard for evaluation, assessment, or comparison; a criterion. |
| position | an objects distance and direction from a reference point |
| newtons 1st law | an object at rest will stay at rest and ban object in object in motion will stay in mottion unless a force acts on and objects |
| newtons 2nd law | |
| vector | |
| velocity |
