A toy car is placed on a ramp. Gravity pulls the car down with 12 N, while friction pushes up with 4 N. What happens to the motion of the car?

• The car moves up the ramp

• The car moves down the ramp with 8 N net force

• The car stays still because the forces are balanced

• The car moves down the ramp with 16 N net force
