| Question | Answer |
|---|---|
| force | a push or a pull |
| balanced forces | forces on an object that combine to give a zero net force and do not change the motion of the object |
| unbalanced forces | the forces acting on a object that cause a change in velocity; making the object speed up, slow down, or change direction |
| net force | the combination of all forces acting on an object |
| at rest | a speed of zero |
| speed | distance divided by time |
| direction | the path that an object is moving or facing |
| motion | a change in an object's position |
| friction | the force that opposes the motion of one surface as it moves across another surface |
| velocity | speed with direction |
| distance | size of the gap between two places |
| rate | a comparison of two quantities measured in different units |
| acceleration | a change in velocity (speed or direction) |
| Newton's 1st law | an object in motion tends to stay in motion & an object at rest stays at rest unless acted upon by an outside force.(Law of Inertia) |
| Newton's 2nd law | the acceleration of an object depends on the mass of the object and the amount of force applied (F=ma) |
| Newton's 3rd law | For every action there is an equal and opposite reaction |
| inertia | the tendency of an object to resist any change in its motion |
| magnitude | The great size or importance of something |
| action | movement caused by a force |
| reaction | resistance or opposition to a force, influence or movement |
| law of conservation of energy | the law that states that energy cannot be created or destroyed but can be changed from one form to another |
