Explain why, wheels are so useful.
You have to push an object if you want to move it from one place to another. You have to apply a lot of force against the friction to make the object move.
In case wheels are used, there will be less friction, enabling you to travel fast without any strenuous effort. Therefore wheels are used.
So wheels make heavy transportation very easy as rolling friction between the wheels and road is comparatively less than static and slide friction,.
