Detailed explanation-1: -In rolling motion with slipping, a kinetic friction force arises between the rolling object and the surface.
Detailed explanation-2: -When a car is on a ramp, a component or part of the force of gravity acts parallel to the ramp, causing the car to speed up, or accelerate down the ramp.
Detailed explanation-3: -Rolling of ball or wheel on the ground is an example of Rolling friction. The other type of friction is sliding friction.
Detailed explanation-4: -In rolling motion without slipping, a static friction force is present between the rolling object and the surface.
Detailed explanation-5: -Complete answer: Rolling friction is a type of static friction because it comes into play when a body is in contact with some surface and it is rotating. Sliding friction comes into play when one body slides over another body and it falls under the category of kinetic friction since the body is in motion.
