A ball held in a person’s hand does not move even though gravity is acting on it because———.

The force of gravity creates a net unbalanced force.

The force of gravity is not strong enough to move the ball.

The force of gravity is balanced by the upward force exerted by the hand.

The force of gravity is less than the force exerted by the hand.
