Question

Give a detailed account of torque and angular momentum

Answer 1

Torque is a rotational analogue of force. It plays the same role in rotational dynamics as force plays in linear motion. Torque is defined as the moment of force or turning effect of force about the given axis or point. It is measured as the cross product of position and force vector while as angular momentum is the rotational analogue of linear momentum. It is axial vector and is measured as the cross product of position and momentum vector

In physics, angular momentum is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a system remains constant unless acted on by an external torque.

: L = Iω

ie moment of inertia*angular velocity

si unit: kg m² s⁻¹

^dimension: M L² T^{−1
They are related to each other just like force and momentum
that is'
torque =rate of cahnge of angular momentum}
