Two equal mass eggs are placed at either end in an egg carton of negligible mass. The egg carton is initially rotated about its middle. If the egg carton is now rotated about one end, what is the final moment of inertia of the eggs relative to their initial moment of inertia? Want Lecture Notes? This is an AP Physics 1 topic.

Three 20.0-gram masses are 9.4 cm from an axis of rotation and rotating at 152 revolutions per minute. What is the moment of inertia of the three-object system? The strings holding the masses are of negligible mass. Rotational Kinetic Energy is also solved for and correct units are determined. Want Lecture Notes? This is an AP Physics 1 topic.
