Question

Define rolling friction define sliding friction define static friction define kinetic friction​

Answer 1

Answer:

When there is no any relative motion, the friction is known as static friction. 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 2

Answer:

Rolling friction:

Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface.

Sliding friction:

Sliding friction (also called kinetic friction) is a contact force that resists the sliding motion of two objects or an object and a surface.

Static friction:

In static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome.

Kinetic friction:

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.
