Learn about friction as you experiment how the movement of vehicles responds to different surfaces and levels of resistance in this great friction game for kids. Which surface slows a vehicle down more - vinyl, wood, carpet or ice? Try and get the car to the end of the track by putting the principles and fun science information you learn about kinetic friction into action. To change the track surface simply scroll through the different surfaces at the bottom of the screen before clicking and dragging the desired surface type on to the track. Kids will enjoy this interactive and educational friction activity.
