The graph below represents an object’s position vs. time.

Which would be the most likely reason for the change in the graph after the 5-second mark?

• Friction is changing as the object is moving.

• Forces on the object are balanced, so it is not moving.

• Forces on the object are unbalanced, so it is not moving.
