Anytime there is a change in motion, force is the responsible party. It has to overcome inertia to act on an object. Inertia keeps an object either sitting still or moving at a constant speed. Learn more about force and motion with this cartoon ani...mation from StudyJams. A short, self-checking quiz is also included with this link.

This NASA video segment explores where the center of gravity is on an airplane, how its location is determined, and why center of gravity is important for maintaining balance. An instructor and an engineer at NASA's National Test Pilot School teach t...hat to control an aircraft, its center of gravity must be located where the wing lift is. Viewers also learn that computers in the aircraft redistribute the weight of fuel to maintain a safe zone for the center of gravity. Demonstrations show how to find the center of gravity of an irregularly shaped object and how the same scientific principles involved in balancing a seesaw apply to balancing an airplane. Viewers also learn that a moment is the product of force times the arm length. Run time 14:10.
