| Use the dynamometer you made to measure the rolling frictional force as you move the toy car across the floor using the horizontal force. Then wedge the wheels of the car (figure out how to do it yourself) and measure the sliding friction force for the same car. Compare the values for rolling friction and sliding friction. What conclusion can be drawn from this comparison?
The rolling friction force is less than the sliding friction force.
