friction
Because when an object is sliding on the other the molecules donnot get time to inter lock properly
A force-meter measures the force of an object pulled along a surface.

If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.
Rolling friction results from momentary attractions between a rolling object and the surface it is rolling on, so as long as the same surface of the bag is always facing the surface, as is usually true for sliding, there is no rolling friction to consider.However, for sliding, there are two different values for friction: the static value, which is how much force must be applied to a resting object to start moving it across a surface; and the dynamic value, which is how much force must be applied to a moving object to make it keep moving with the same velocity.

A baseball rolling along the floor has inertia. The amount of inertia depends on the mass of the object. The greater the mass or weight, the greater the inertia.
you play crazybones by setting them up and rolling them along a surface

YES
friction
When an object rolls the center of gravity (or of geometry - or both depending on the shape of the object) translates (moves) along a path and there is a point of contact with a surface on the perimeter of the object, rotation (angular change) does occur too.During rotation the center of gravity could be motionless and there is probably no point of contact with any surface; the movement is purely angular.

Friction - the force that makes it difficult for one object to slide along the surface of another
Rolling Friction is caused by a rolling object such as a wheel when rolling over a surface. Sliding friction is cause by the brishing of an object along with the medium that it is sliding on. This can be visualize by sliding down a hill with a sled in the snow. Fluid friction, by fluid we are alluding to any substance that flows. Therefore air and water for both examples are fluid. When swimming or when is a bird is flying fluid friction is being acted upon them Good luck Stephane E. Fouche
