In this simulation, we can change values of friction for a block and solid sphere moving on an inclined plane with any chosen velocity. Observe the direction of friction and motion of bodies and compare them to understand rotational concepts.
WebThe three laws of rolling friction: (1) With the increase in smoothness, the force of rolling friction reduces. (2) Rolling friction can be written as a product of load and constant to the given fractional power. (3) The rolling friction force is inversely proportional to the curvature radius and it is directly proportional to load.
