What is the relation between torque and angular momentum ? |
|
Answer» Solution :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)` |
