Questions + Answers key
Take MCQ Physics Test1.
About which axis the moment of inertia of a body is minimum?
2.
A cat is able to land on its feet after a fall. Why?
3.
Two boys of the same weight sit at the opposite ends of a diameter of a rotating circular table. What happens to the speed of rotation if they move nearer to axis of rotation?
4.
What is the power needed to maintain uniform circular motion?
5.
Why centripetal force cannot do work?
1.
The moment of inertia of a body is minimum about an axis passing through its centre of mass.
2.
When a cat falls to ground from a height, it stretches its body along with the tail so that its moment of inertia becomes high. Since angular momentum (L = Iω) remain constant, the value of angular speed ω decreases and therefore the cat is able to land on the ground gently.
3.
The moment of inertia of the system (circular table + two boys) decreases. To conserve angular momentum (L = 100 = constant), the speed of rotation of the circular table increases.
4.
No power is needed to maintain uniform circular motion.
Power required = \(\bar{F}.\bar{v}=F v\cos\theta\)
= \(Fv\cos90°=0\)
5.
The centripetal force cannot do work on the object since it is always perpendicular to the velocity.
