Know It All: Lift | Nasa Online
An upward force called lift acts on the airplane and opposes the downward forces of gravity. The lift force allows the airplane to get off the ground and stay in the air. Watch the simulation to see how this works.
American Geosciences Institute
American Geosciences Institute: Wind Classroom Activities
When air is warmed, it expands and becomes less dense. As the air becomes less dense, its air pressure decreases. This occurs because molecules in warm air have greater kinetic energy (energy of motion) than in cold air. As the molecules...
