What is the difference between a balenced and unbalanced force?

- 0 (zero) net force= balanced forces - the speed continue nonstop so there is no change in the object's motion.
EX: football players blocking each other, thumb wrestling
- Net force is not zero- unbalenced forces- causes the speed, direction, or both to change (acceleration).
EX: pushing a broken down car, pushing a pull door
- The force must be strong enough to beat the object's state of rest.
