ESSAY
1. ANS:
Two forces that act on the ball as it moves through the air are gravity and friction. Gravity causes the ball to
move downward toward Earth. Friction causes the ball’s motion to get slower the farther it moves through the
air. Because the ball’s velocity is changing as it moves, it can be determined that the forces acting on the ball
are unbalanced.
