Question

The combination of rotational speed and transfer speed is called​

Answer 1

Answer:

Rolling is a combination of translational and rotational motion. When an object experiences pure translational motion , all of its points… move with the same velocity as the center of mass; that is in the same direction. with the same speed (v = v cm)

Answer 2

The combination of rotational speed and translational speed is called the rolling motion.

• The most common example of rolling motion is the rolling of the wheel where the centerline of the wheel is the centerline of rotation while it is rolling.
• For the combination of rotational speed and translational speed that is the rolling motion, the kinetic energies are simply the total sum of rotational and translational motion. In simple words, the kinetic energies of this combined motion acquire the additive property.
• The special case of this rolling motion is the rolling devoid of slippage.  This application can be seen when we drive a car on a road that is dry.
