|---|---|
| Force | A force is described by its magnitude and by the direction in which acts |
| Newton | The overall force on an object when all the individual force acting are added together |
| Balanced Forces | Balanced Forces acting on an object do not change velocity |
| Friction | Two surfaces exert pressure on each other |
| Static | Friction that acts on objects that are not moving |
| Sliding | Friction that occurs when one solid surface slides over another |
| Fluid | A material that can easily flow |
| Rolling | Friction that occurs when an object rolls over a surface |
| Gravity | Force that pulls objects towards ejo gravity acts everywhere and on everything = law of universal surface |
| Mass | The amount of matter in an object |
| Weight | The amount of gravity on an object |
| Free Fall | Force of gravity alone causes an obj to accelerate |
| Air Resistance | Fluid friction of air acts on obj to accelerate |
| Elastic Forces | If it returns to its original shape after is squeezed or streched |
| Inertia | The tendency of an object to resist any change in its motion |
| Momentum | You can calculate the movement of a moving object by multiplying the objects mass and velocity |
| Law of Conservation of Momentum | The total momentum of any group of object remains the same |
| Net Force | The overall on an object when all the indidual foce acting on eachother |
