The force of friction depends on the area of contact between the two surfaces. ... As the area of contact is less in the case of rolling than in the case of sliding, rolling friction is less than the sliding friction.

Why is rolling friction the weakest?

The object has a harder time overcoming the resistance force when sliding. Rolling friction is weaker because basically, it is rolling. The rolling motion or cyclical motion allows it to move, change direction, or change speed more easily. Rolling something is better at overcoming the resistance force.

Why is rolling friction less than static friction?

Rolling Friction is less than sliding or static friction because in rolling friction the surface area in contact is least and friction depends on surface area. ... Static friction is when the body impend for motion and sliding friction is when body overcomes the static friction and starts sliding.
