• All forces acting on the ball moved in the same direction.

Which of these has an unbalanced force?

• a book sitting undisturbed on a desk

• a child standing in a line that is not moving

• a ball that is slowing down as it rolls on the ground along a straight line

• a meteoroid moving at a constant speed and direction through outer space
