## Science & MotionBy: Rett Andersen and Aidan Kane

### Balanced Forces

Equal forces acting on an object in opposite directions. All forces acting on an object balanced; so there is no change in motion or speed.

This nail has balanced forces acting on it, therefore it is not moving.

### Motion

Motion is a change in position relative to another object.

This car is in motion resulting in a change in position.

### Unbalanced Forces

Force on an object that are unbalanced and result in the movement of the object.

The guy that is winning has more force which makes an unbalance force.

### Speed Calculation

#### S=d/t

Rett runs 100 meters in 14 seconds. What is his speed?

### Speed

The distance an object moves in a given amount of time.

#### Example:

80 km/hr

This motorcycle is moving 80 kilometers per hour.

### Speed Graph

The red line went at a constant speed of 2 m/s, then it stopped at 8 m for 3 s then it returned to the starting point at 2.7 m/s. You find the speed by taking a point in the line then you divide the distance by the time.
