But beyond the fun and excitement that is gained from playing with paper airplanes, there is a lot to learn about the physics of the plane. ... The plane gains lift by moving through the air with the initial velocity that is created by throwing the plane. ... The paper airplane's velocity will quickly decrease, due to the drag, and the plane will fall to the floor. In terms of physic, the airplane is staying afloat because it is trading potential energy for kinetic energy, which equals velocity. ... The particles are free to move about and interact with the top and the bottom of t...

He was the only member of his family to make a mark in physics. ... The Hydrodynamica is both a theoretical and a practical study of equilibrium, pressure and velocity of fluids. He put forward what is called Bernoulli's principle, which states that the pressure in a fluid decreases as its velocity increases. ... About 1738, his father published Hydraulica; this attempt by Johann to obtain priority for himself was another instance of his antagonism toward his son. ... In 1732, he accepted a post in a botany and anatomy at Basel; in 1743, one in physiology; and in 1750, one in physics. ...

The reason for this is virtually everything about how they accomplish flight is species specific! ... The physics which permit flight in insects is similar to that of an airplane. The body and wing morphology create a higher air pressure under the wing relative to the air above the wing because the shape of the wing induces a larger air velocity above the wing than under it. ... Both are necessary during flight because a strong wind could indicate a high velocity when the insect may not be moving forward at all ( Goldsworthy and Wheeler, 1989 ). ... At first I was disappointed I...
