| Velocity | Speed of an object and its direction |
| Momentum | Mass x Velocity |
| Gravity | Force of attraction that depends on mass of two objects |
| Weight | A measure of force and gravity |
| Net Force | Two or more forces that are acting on an object at the same time |
| Balanced Force | Forces on an object that are equal in size and opposite in direction |
| Friction | A force that acts in a direction opposite the motion of the moving objects, causing an object to slow down and stop |
| Types of Friction | 1. Rolling Friction 2.Liquid Friction 3.Sliding friction 4.Static Fraction |
| Inertia | The tendency of an object to resist any change in motion |
| Force | Mass x Acceleration |
| 2nd law of motion | The greater the force the more acceleration |
| 3rd law | For every action there is an equal or opposite reaction |
