Torque or moment of a force about the axis of rotation
τ = r x F = rF sinθ n
It is a vector quantity.
If the nature of the force is to rotate the object clockwise, then torque is called negative and if rotate the object anticlockwise, then it is called positive.
Its SI unit is ‘newton-metre’ and its dimension is [ML2T-2].
In rotational motion, torque, τ = Iα
Where a is angular acceleration and 1is moment of inertia.
