2) Static friction is a force that keeps an object at rest .The term sliding friction refers to the resistance created by two objects sliding against each other . This can also be called kinetic friction . Sliding friction is intended to stop an object from moving

3) Friction is caused due to irregularities on the surfaces of objects in contact.If we carefully observe the surface of objects through magnifying lens we will see that there are tiny hills and grooves . When two surfaces come in contact with each other these hills and grooves interlock with one another and thus oppose motion .

Answer:

Rolling friction occurs when a wheel, ball, or cylinder rolls freely over a surface, as in ball and roller bearings. The main source of friction in rolling appears to be dissipation of energy involved in deformation of the objects. If a hard ball is rolling…Rolling friction and sliding friction are caused by the rubbing of the surfaces together. The surface of the floor is rubbing the surface of the moving body. This rubbing results to heat produce during the process and the motion of the body is impeded.
