For example, a toy car made of metal will roll farther than a toy car made of plastic because metal has a lower coefficient of friction than plastic. This means that there will be less resistance to the motion of the metal car, and it will be able to roll farther.
In addition, the surface that the toy car is rolling on can also affect the distance it will travel. For example, a toy car will roll farther on a smooth surface than on a rough surface. This is because there will be less friction between the car and the smooth surface, and the car will be able to roll more easily.
Therefore, both the material that the toy car is made of and the surface that it is rolling on can affect the distance it will roll.
