Question

an
obtain
expression
for torque with anglar acclration and linear momentum with
the anglar acceleration​

Answer 1

ANSWER

A system rotating with an angular momentum in presence of a torque suffers a change in the angular momentum and the rate of change of angular momentum is directly proportional to the torque acting on it.

If I be the moment of inertia of the system and ω be the angular velocity then angular momentum L=Iω

Rate of change of angular momentum provided the shape of system does not change is :

τ=

dt

d

(Iω)=I

dt

dω

=Iα

α is the angular acceleration and τ is the torque.

Dimension of Torque is [ML

2

T

−2

] and its unit is Newton- metre (N⋅m)....
