define kinetic friction and explain sliding and rolling friction?
Answers
Answer:
When a body slides over another one, the friction acting there is known as sliding or kinetic friction. When a body rolls over another one, the friction acting there is known as rolling friction.
Answer:
Kinetic friction is defined as a force that acts between moving surfaces. A body moving on the surface experiences a force in the opposite direction of its movement. The magnitude of the force will depend on the coefficient of kinetic friction between the two material.
Explanation:
Rolling friction takes place when an object rolls on the surface. Sliding friction takes place when two surfaces are rubbed against each other.
Rolling friction takes place due to the deformation of surfaces. Sliding friction takes place due to interlocking between microscopic surfaces.
