What is an unbalalnced force

Unbalanced forces

Unlike balanced forces, we say unbalanced forces when two forces acting on an object are not equal in size.

Unbalanced forces causes can cause:
pressure bulleta still object to move
pressure bulleta moving object to speed up or slow down
pressure bulleta moving object to stop
pressure bulleta moving object to change direction

Unbalanced forces make the wagon in the diagram speed up.
example of unbalanced forces
Notice that because there is a bigger force and a smaller force involved, the direction of the wagon will be determined by the bigger force. The wagon is moving as a result of unbalanced forces.
