To move a object in Linear Direction we need a Force (F). Similarly to move an object in Angular direction we need Torque().

Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. Also called turning effect of force.or Moment of force.

If we push a pull something by applying a Force (

**F**) . It creates a linear motion.

But if an object is tied to a string and a force is applied on it. It moves in angular motion. and the Force here will be called Torque. Or we can say what is Force in Linear Motion. is Torque ( ) in Angular Motion.

see example:

So more Force or Torque here is applied so more angular velocity/acceleration is generated.

Amazing thing about this Angular motion is that when the radius the string increase the less torque is required to move.

In other words more force is applied further away in radius the less torque is required.

If force is applied perpendicular it will create max impact.

where

*F*_{⊥}is the amount of force directed perpendicularly to the position of the particle. Any force directed parallel to the particle's position vector does not produce a torque.^{[7]}^{[8]}
It follows from the properties of the cross product that the

*torque vector*is perpendicular to both the*position*and*force*vectors. Conversely, the*torque vector*defines the plane in which the*position*and*force*vectors lie. The resulting*torque vector*direction is determined by the right-hand rule.
So we can say

Torque is a perpendicular force acting on an Axis from a Distance.

you can lift a larger weight by using a longer lever.

The units of torque. N.m , Kg.m , lb.ft

these are product of Force and Distance.

more force more Torque. and more Distance so more Torque.

we use rench to move a nut.

the bigger the rench the less the force required.
