When a car moves forward, in which direction do its wheels push on the road?
Try this little experiment!

You Need:

1 toy car, battery-powered or wind-up
10 or more soda straws
1 sheet of thick cardboard, or Styrofoam, as in the photograph

Place the car at one end of the 'road' as in the above photograph, and then start the car. Watch what happens to the 'road' as the car moves forward.
Do the wheels push forward or backward?
Why does the car move forward?

Forces are never lonely. They always occur in pairs. The spinning wheels of the car push backward on the ‘road’. The ‘road’ exerts an equal force on the wheels of the car, but in the opposite direction. This is an example of Newton’s Third Law of Motion.
