Question

(13) Define the terms: (i) Torque (ii) Angular momentum in
relation to rotational dynamics of a rigid body.
​

Answer 1

Explanation:

Relation between torque and angular momentum is given by

r

net

=

dt

d

L

where,

r

→ torque acting on a body

L

→ angular momentum of body

Now if,

L

= constant

So,

dt

d

L

=0

⇒

r

net

=0

Hence,

If a body is rotating with constant angular momentum then, the net torque on the body will be zero.
