The 4 Forces of Flight

By, Kendall Baker

Force 1: Weight

Weight, or gravity acts as a downward force pushing things to the center of the Earth.

Force 2: Lift

Lift acts like a right angle to the direction of motion through air.

This is caused by differences in air pressure.

Force 3: Thrust

Thrust propels the the object in motion.

Engines give thrust.

Force 4: Drag

This is the force that acts in opposition to the direction in motion.
