Question

What is the cause of rotational motion?

Answer 1

1. Rotational motion kinematics describes the relationships between the angle of rotation, angular velocity, angular acceleration, and time.
2. It only describes the motion and excludes any forces or masses that may influence rotation.
3. Torque is a force that can cause an object to rotate around an axis so it causes rotational motion.
4. Thus, that force causes an object to accelerate in linear kinematics, torque causes an object to acquire angular acceleration.
5. As a result, angular momentum occurs in a rotational motion.
6. Its best example is the movement of a spinning top.

Hence, Torque is the cause of rotational motion.
