Principle Demonstrated by the Wheel's Force on the Ground

Newton's Third Law of Motion is the principle shown when there is friction between a car's wheel and the ground, and the wheel exerts a horizontal force on the ground.

• When the car's engine turns the wheels, the wheels push backward against the ground at the contact point due to static friction.
• According to Newton's third law, the ground pushes forward on the wheel with an equal and opposite force. This forward static friction force is what accelerates the car

• The forces do not cancel because they act on different objects: the wheel exerts a force on the ground, and the ground exerts a force on the wheel

Summary:
The interaction where the wheel exerts a horizontal force on the ground (via friction), and the ground exerts an equal and opposite force on the wheel, directly demonstrates Newton's third law of motion: For every action, there is an equal and opposite reaction
