Answer

Brief Explanations:

  1. When an object is at rest, the forces acting on it are balanced according to Newton's first - law. Unbalanced forces cause a change in motion.
  2. When an object changes its position, it is in motion.
  3. Newton's third law states that for every action, there is an equal and opposite reaction. A baseball hitting a bat at the same time the bat hits the ball is an example of this law as the bat exerts a force on the ball and the ball exerts an equal and opposite force on the bat.

Answer:

  1. C. balanced
  2. B. in motion
  3. B. A baseball hitting a bat at the same time the bat hits the ball.
