### may the mass time acceleration be with you

## Examples of motion

## Acceleration A measure of how much velocity changes in a given amount of time. In order to accelerate, an object's speed, direction or both must change. The faster the velocity change, the greater the acceleration. The formula is V2-V1/T when V2 is the final V and V1 is the original V. | ## Force Force is a push or pull on an object. It gives energy onto an object causing it to accelerate in a variety of ways. It is measured in Newtons. Balanced forces cancel out while unbalanced cause an acceleration in one direction. The net force is the overall combined force acting on an object. | ## Velocity/Speed Speed and velocity both represent the distance traveled by an object divided by the time it took. The difference is that velocity includes a direction. In other words, speed is a scalar quantity while velocity is a vector quantity. |

## Isaac Newton

Isaac Newton was a mathematician and physicist in the 1600's. He wrote

*The Principia*and is well known for his work in gravity and optics. He is most famous for his laws of motion.
