Question

State and explain Newton’s second law for

rotation. Prove that T = I⋅ ∝ .​

Answer 1

Answer:

Newton’s second law of motion states that the force exerted by a body is directly proportional to the rate of change of its momentum. For a body of mass ‘m’, whose velocity changes from u to v in time t, when force ‘F’ is applied.

F∝ Change in momentum/time

F∝ mv−mu/t

F∝m( v−u/t)

⇒F∝ma⇒F=kma(∵a= v−u/t)

⇒F=ma(∵k=constant=1)
