A toy car was used in an investigation about forces. During which of the following scenarios was the car experiencing balanced forces?

• The toy car speeds up as it rolls down a ramp.
• The toy car travels forward at a constant speed.
• The toy car slows down as it rolls up a hill.
• The toy car changes direction at a constant speed.

The diagram below shows a toy car moving along a smooth, frictionless track. In which sections of the track will this toy car experience unbalanced forces?
