If the two forces on an object are equal in size and opposite in direction, the forces are balanced, and no change
in motion results. Which of the following situations is an example of balanced force acting upon an object?
O A rope being pulled from both sides with equal force
O An 11-gram pen falling off a table onto the floor
O A car moving constantly at 30 miles per hour
O A rock accelerating as it rolls down a hill
