A heavy bell attached to a rope and a pulley system is being lifted. Which statement BEST describes the forces acting on the bell according to Newton’s first law of motion?
The forces are unbalanced so the bell will not move.
The forces are unbalanced so the bell will move.
The forces are balanced so the bell will not move.
The forces are balanced so the bell will move.
A ball is sitting at rest on a field and then it is kicked. Which statement BEST describes the forces acting on the ball?
The forces are unbalanced when the ball is sitting on the field because it is not moving; the forces are balanced when the ball is kicked because the ball is in motion.
The forces are balanced when the ball is sitting on the field because gravity is pulling it; the forces are unbalanced when the ball is kicked because gravity is not pulling it.
The forces are balanced when the ball is sitting on the field because it is not moving; the forces are unbalanced when the ball is kicked because the ball is in motion.
The forces are unbalanced when the ball is sitting on the field because gravity is pulling it; the forces are unbalanced when the ball is kicked because gravity is not pulling it.
