What are the conditions for slipping without rolling and rolling without slipping?

Question

When a ball or a ring is placed on a surface,it can slip,roll or slip with rolling....under what conditions are each of these executed??It probably has something to do with friction.

Answer 1

As the ball moves due to a certain force F it is a subject to an apposing friction force f. Note that either the ball can move or the surface upon it moves. Both forces are tangential to the ball at the point of contact between it and the surface.

also f=uN
u- coefficients of friction
N - force exerted by the ball on the surface

If F< f the ball rolls
if F> f the ball slips
if F= f will probably slip with the roll

Answer 2

lets take the case of a wheel moving on a plane surface. lets assume its center of gravity has a linear speed v, its radius r and angular velocity w. Now the wheel will roll without slipping if v = r*w. It will skid when v > r*w and roll if v < r*w.
It has to do with friction in a way that the values of v and w will depend upon the friction between the surface and the wheel.

Answer 3

Yes - something with friction, based on the surface of the object. Rollable object is circular and if the object is not circular, (perfect rolling is not possible) those are slippable. Besides, while an object moving along above the earth surface, (refer theory of relativity), and when a force behind is supporting it, on such occasions, when the front side is hindred, it would roll, based on the weight of the rear side of the object at the time of hiting. On the contrary, if the rear side is more heavy, it would slip. (Ref : MVar's 2nd Rule of motion.) Examples, a running man or a two or four wheel vehicle.

Answer 4

think there replaced into no friction in any respect. Then the only forces appearing on an merchandise could be gravity and the reaction rigidity from the ramp. For a uniform ball or cylinder, the two those will act interior the path of the centreline and for this reason exert no torque, so the item will slide with out rotating. it is why we'd desire to tell apart between rolling with out slippage and sliding with slippage. (no count if there's a value for coefficient of friction which will enable an intermediate between the two extremes - some slippage, yet nonetheless some rotation - i do no longer know.)

Answer 6

Please buy a book called "Concepts of Physics" by H.C.Verma
and study the chapter "Rotational mechanics" , all your doubts related to rotational motion will be cleared.
