Question

Name the quantity which can bring rolling without slipping

Answer 1

When a body is rolling it undergoes :
-->Rotational motion and
---> Translation motion

Friction is required to start rolling.
Rolling without slipping is called as " Pure friction"

For example;
Wheels of car are in rolling motion.
Different particles of the body will experience different velocities.
Angular velocity of wheel=ω
Translational velocity=Vcm
Liner velocity due to rotational motion: ωr
V=VCm+vr
Vr,po= ωr
For any rolling body , If Vcm=ωr, then the body rolls without slipping.

If vcm<ωr, then object has some backward slipping and the rolling is called Backward slipping.

If Vcm>ωr the rolling is called "rolling with forward slipping"

Answer 2

Answer:

Explanation:

Rotatinal and translational motion

Friction is a rolling without slipping e.g. wheel of a car
