A student is conducting an experiment involving inertia with a dozen eggs, one of which is hard-boiled. Inertia is defined as the property of matter by which it resists any change in velocity. The student spins each egg and then touches it to stop the egg from moving. The student observes that the hard-boiled egg spins and stops easily as it is touched, but the raw eggs continue moving even after being touched to stop the spin. Why does the hard-boiled egg stop spinning so easily? Why do the raw eggs continue trying to move? How does this experiment reference inertia?
