Torque

Definition

Torque is the measure of how effectively a force can cause an object to rotate. It depends on the magnitude of the force, the distance from the axis of rotation, and the angle between the force and lever arm.

Rotational inertia:

Rotational inertia, also known as moment of inertia, is a property that determines an object's resistance to changes in rotational motion. It depends on both mass distribution and shape.

Angular acceleration: Angular acceleration refers to how quickly an object's angular velocity changes over time. It is caused by torque acting on an object with rotational inertia.

Lever arm: The lever arm is defined as the perpendicular distance between an axis of rotation and a line along which a force acts. It plays a crucial role in determining torque.
