What is the relation between torque and angular momentum ?

Explanation

We have the expression for magnitude of angular momentum of a rigid body as, `L = I omega ` . The expression for magnitude of torque on a rigid body is, `tau = I alpha `
We can further write the express.ion for torque as,
` tau = 1 (d omega )/(dt) " " ( because alpha = (d omega)/(dt) )`
where `omega` is angular velocity and a is angular acceleration. We can also write equation,
`tau = (d(I omega))/(dt)`
` tau = (dL)/(dt)`
