mass - A property of air demonstrated by weighing one full and one empty balloon, space - A property of air demonstrated by putting a cup straight down in some water, pressure - A property of air that can be demonstrated by blowing up a balloon, gravity - the constant force pulling objects towards the center of the Earth, lift - a force generated by objects moving through a fluid. Lower pressure on the top and higher pressure on the bottom causes this., thrust - the engine of an aircraft creates this, it pushes the aircraft forward., drag - This is unwanted in flight and makes engines work harder. It is the resistence of the air you are moving through, velocity - A science-y word for speed, bernoulli - The scientist who discovered that faster moving air creates lower pressure, aerodynamic - When an object is a specific shape that reduces drag, flight - The action or process of flying through the air., rises - Hot air does this, glider - This type of aircraft has no engine and uses thermals to increase altitude in flight,
