If a huge stone could not be rolled off the road by many people, it can be done by a few people assuming a way is found to reduce the frictional force between the road and the stone.
The force that is acting against the motion of the stone that hinders many people from not being able to roll it off is friction. The frictional force acts between the stone and the road.
If a way can be found to reduce the opposing friction force, fewer people can actually roll off the stone.
There are several ways to reduce frictional force. These include but not limited to;
- lubricating the contact surfaces
- making the contact surfaces less rough
- use of ball bearings between surfaces
