Hinged Stick	The acceleration of the stick is more than the acceleration of ball. Thus, the stick's cup will be in place to catch the ball even though both are released at the same time.	Real	Real MPG	Mechanics 1Q20.50
Hollow Globe in Vacuum	When in the atmosphere, the globe experiences a buoyancy force upward exerted by air. When the air is removed, the buoyancy force is also removed and it is clear that the globe weighs more than the cylinder.	Real	Real MPG	Fluid Mechanics 2B40.40
Horse and Rider	Only the center of mass of an object needs to be supported in order to support the object. The horse and rider's center of mass is under the hind legs.	Real	Real MPG	Mechanics 1J20.35
