Net torque on a sphere is the measure of the rotational force acting on a sphere. It is the product of the force applied to the sphere and the distance from the axis of rotation to the point where the force is applied.
To calculate net torque on a sphere, you need to first determine the magnitude and direction of the force acting on the sphere. Then, you need to find the distance from the axis of rotation to the point where the force is applied. Finally, multiply the force by the distance to get the net torque.
The magnitude of the force applied, the distance from the axis of rotation to the point where the force is applied, and the angle between the force and the radius vector all affect the net torque on a sphere.
Net torque and angular acceleration have a direct relationship. The net torque acting on a sphere is equal to the moment of inertia of the sphere multiplied by its angular acceleration.
The distribution of mass affects net torque on a sphere because it determines the moment of inertia of the sphere. A sphere with more mass concentrated near its axis of rotation will have a smaller moment of inertia and therefore require less torque to rotate, while a sphere with mass distributed further from the axis of rotation will have a larger moment of inertia and require more torque to rotate.
