what is moment of inertia and how it work with example??
Answers
It is the rotational analogue of inertia it is the product of the position vector and the inertia of an object... it works the same as inertia but in a rotational. manner
The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body. ... The moment of inertia depends on how mass is distributed around an axis of rotation, and will vary depending on the chosen axis.
Moment of Inertia Example
Imagine you are on a bus right now. You find a seat and sit down. The bus starts moving forward. After a few minutes, you arrive at a bus stop and the bus stops. What did you experience at this point? Yes. When the bus stopped, your upper body moved forward whereas your lower body did not move.
hope it helps you
