Answer

Brief Explanations:

Unbalanced forces cause changes in motion. When a weight speeds up as it falls, there is a net - force acting on it (gravity and air resistance with a net - effect causing acceleration). A bumper car hit by another car changes direction and moves off at an angle, indicating an unbalanced force. A balloon flying across the room when air is released has a net - force from the air expulsion. A garbage can at rest has balanced forces (gravity and normal force). A hockey puck moving at a constant speed in a straight line has balanced forces (no net - force causing a change in motion).
