Explain the difference between a balanced force and an unbalanced force. Give an example of each.
Explain the difference between a balanced force and an unbalanced force. Give an example of each.
Balanced forces act on two objects but the objects do NOT move because the net force equals 0. An example is a book sitting on the top of a desk.
Unbalanced forces act on two objects and the objects DO move or change direction because their net force is GREATER than 0. For example, a ball moves after someone kicks the ball.
