Video Demo: Apple Inertia
Sunday, August 22, 2010 at 8:48AM
Inertia is the tendency of an object to resist a change in its motion. An apple and a knife are moving downward. The counter-top applies an unbalanced force upward on the knife. The knife decelerates, but the apple does not. The apple decelerates only when the knife handle applies a force upward on it.
