What is a Balanced Force?

Back

Balanced Forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an Unbalanced Force?

Back

Unbalanced Forces are not equal and can cause an object to start moving, stop moving, or change direction.

What is the effect of Net Zero Force on an object?

Back

Net Zero Force means that all forces acting on an object are balanced, resulting in no change in motion.

What is the direction of force in a tug of war when one team wins?

Back

The direction of force is towards the winning team, indicating an unbalanced force.
