Lesson: Angular Momentum in Terms of Moment of Inertia Physics • 9th Grade
In this lesson, we will learn how to calculate the angular momentum of an object that is rotating from its moment of inertia.
If the angular speed of a rotating object increases by a factor of 3, by what factor does the angular momentum of the object change?
A hollow metal sphere has a moment of inertia about its axis of rotation of 0.45 kg⋅m2 and an angular momentum of 0.79 kg⋅m2/s. How long does it take for the sphere to make one full rotation? Give your answer to one decimal place.
An object spinning with an angular speed of rad/s has an angular momentum of kg⋅m2/s. What is the moment of inertia of the object about its axis of rotation?
