Explanation:
I think
When an object is rolling on a plane without slipping, the point of contact of the object with the plane does not move. A rolling object's velocity v is directly related to its angular velocity ω , and is mathematically expressed as v=ωR v = ω R , where R is the object's radius and v is its linear velocity.
Answer:
Rolling Motion.
Every one of you must have seen a ball rolling down a hill or rolling of bike wheels when the bike is moving. You must have also seen the motion of a bowling ball or a motion of snooker ball on the table. These are nothing but the examples of a rolling motion. Now let us study this in detail.
Let us understand the concept of “Rolling Motion”. Imagine a box sliding down from an inclined plane. This is an example of a translation motion. They have the same velocity at an instant of time. The motion of a ceiling fan or a merry go round are the examples of rotational motion. Here in rotational motion, every particle of the body moves in a circle. Rolling motion is the combination of rotation and translation..
For example, an object, say a ball is in rolling, that is it is rolling on the surface of the ground. So the ball is in the rotation motion. At the same time, the ball is moving from one point to another point so there is a translation motion. At any instant of time, there is one point which is always in contact with the surface. So that point is at rest.
