Balanced vs Unbalanced
Balanced Unbalanced
If there is acceleration, then there is an unbalanced force.If acceleration is zero, then the forces are balanced.

Are these balanced or unbalanced forces?

Remember: Acceleration is any change in velocity! Slowing down, Speeding up, or changing direction.
Acceleration equals zero if an object is not moving, or if it is moving at a constant velocity.

Contact and Action-at-a-Distance
•Contact Forces- Those that need to physically touch an object.
•Action-at-a-Distance Forces- Those that do not need to touch an object.
