Which factor affects the speed of a rotating object on a turntable?

The speed of a rotating object on a turntable is significantly influenced by the distance from the center. As an object moves away from the center of rotation, it travels along a larger circular path. This means that for the same amount of time, the object farther from the center must cover a greater distance than an object closer to the center. According to the principles of rotational motion, the further an object is from the center, the greater the linear speed it must attain to maintain the same angular velocity as objects closer to the center.

In rotational motion, angular velocity is defined as the rate of rotation and is the same for all points on a rigid body. However, linear speed, which is the distance traveled per unit of time, varies with the radius of the circular path. Therefore, the distance from the center plays a critical role in determining the speed of the object as it rotates on the turntable.

The influence of weight, color, and shape is either minimal or irrelevant in this context. While weight can affect the stability of an object on the turntable, it does not directly influence the speed of rotation. Similarly, color and shape do not have any effect on the speed of a rotating object. Thus, the key factor that determines the speed
