Torque physics

In physics, when an external force is applied on the body, the body gets tendency to rotate over an axis called torque.Torque physics is considered as a vector quantity over an axis of rotation. The multiplication of the force magnitude and the perpendicular distance of the line. Torque is mainly for change the state of rotation. The other name of torque is a moment of force.

Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label 'O'. We will call the force 'F'. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by 'r'. Note that this distance, 'r', is also a vector, and points from the axis of rotation to the point where the force acts

The concept of torque, also called moment or couple, originated with the work of Archimedes on levers.

The rotational analogues of force, mass, and acceleration are torque, moment of inertia, and angular acceleration respectively.

The force applied to a lever, multiplied by its distance from the lever's fulcrum, is the torque. For example, a force of three newtons applied two metres from the fulcrum exerts the same torque as one newton applied six metres from the fulcrum.
