| Term | Definition |
|---|---|
| Balanced force | Equal to 0 and have a net force of 0 |
| Unbalanced Forces | Net force above 0 and objects that change their motions and are moving |
| Newtons first law | A body at rest will remain at rest in till extract force is added and a body in motion will remain in motion |
| Newtons second law | F=MxA= force equal mass times acceleration |
| Newtons third law | For every action their is an equal but oppisite reaction |
| 3 factors to describe the motion of an object | Direction, how far it has traveled, and time it is in motion |
| potential energy | Potential energy is stored energy based off of an objects position. To increase an object's potential energy, move it to a higher position. To decrease its potential energy, move it to a lower position. |
| potential energy is also | A reduction in height would decrease potential energy which would result in less kinetic energy. |
| formula for kenetic energy | K.E=0.5xMxV2 |
| kentic energy | When velocity doubles k.E increases by 4 |
| speed and kenetic energy = | Not a straight line non linear |
| mass and kenetic energy= | straight line or linear |
