They use the spring …

WebFriction is the resistance of motion when one object rubs against another. Anytime two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction. When one object is sliding on another it starts to slow down due to friction. This means it loses energy. gateway college prepWebJun 9, 2015 · Results. Our cars travelled further if the gradient was steeper, this is because a steeper gradient allows the car to pick up more speed. The cars travelled less far when we used the carpet surface than when we used the smooth surface.
