Differentiate between sliding friction and rolling friction?
Sliding friction | Rolling friction |
1. When an object slides over the surface of another object then the force of friction generated between the two surfaces is known as sliding friction. | 1. When an object rolls over the surface of another object, then the force of friction generated between two surfaces is known as rolling friction. |
2. This is also known as kinetic friction and is defined as a force that is needed to keep a surface sliding along another surface. | 2. The force resisting the motion of a rolling body on a surface is known as rolling friction. |
3. When we rub our hands together, heat is created between both the hands, this is due to the sliding friction generated between both the hands. | 3. We see basketball rolls on the court will eventually come to a halt because of rolling friction. |
