Science & Motion By: 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 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


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

S=d/t S=100 m/14 sec S=7.1 m/s


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


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.
