Unbalanced Forces & Acceleration
... Unbalanced Forces and Velocity (cont.) • An unbalanced force applied to a moving object in the same direction as the motion speeds the object up. • An unbalanced force applied to a moving object in the opposite direction as the motion slows the object down. • Friction is applied in the opposite dire ...

... A sailboat is moving at a constant velocity. (a) Is work being done by a net external force acting on the boat? Explain. (b) Recognizing that the wind propels the boat forward and the water resists the boat's motion, what does your answer in part (a) imply about the work done by the wind's force com ...
