Sir Isaac Newton told us about gravity and gave us a simple elegant equation to calculate it. The force of gravity is proportional to ___ of two objects and inversely proportional to their _____.

Daniel Bernoulli told us about the physics of fluids and described it mathematically telling us that [ (density x velocity^2 / 2) + pressure = constant ] which means fluid velocity is inversely related to its pressure. A flying Frisbee floats partly because the velocity of air passing over the Frisbee's _____ is ______ than the air velocity passing the bottom therefore creating higher pressure on the Frisbee's bottom creating lift.
