Two objects A and B are moving on a rough surface as shown in figure. Object A has greater velocity than B, then, which object experiences more frictional force?

Understand the Problem

The question is about comparing the frictional forces experienced by two objects of different masses moving on a rough surface. It asks for an understanding of how mass and possibly velocity affect the frictional forces acting on the objects.

More Information

Frictional force depends on the normal force, which in this case is determined by the mass of the objects. Since B is heavier, it experiences more friction.

Tips

A common mistake is to think velocity affects frictional force directly, but friction only depends on the weight and coefficient of friction in this context.
