Flight of the Bat.
A bat's wings are similar to how human hands are constructed, with five fingers. Except, there's a thin membrane of skin that links these "fingers" together. The bats' wings can fold, which is one thing that allows them to fly. They use a rowing motion to fly--thrusting their wings so that air can kind of surround their wings and create lift. This allows bats to fly, and stay aloft in the air! -
Thrust.
Thrust is one of the principles of flight. Thrust moves an object in the direction of a motion; it is created by air being pulled in and pushed out. -
Drag.
Drag is one of the principles of flight. Drag acts in the opposite direction of an object's motion, "pulling it back" kind of. It's caused by friction and differences in motion. -
Lift.
Lift is one of the principles of flight. Lift is what allows an object to "fly". It keeps the object upwards, and it is a force. Fun Fact: Lift is a vector quantity!! -
Weight.
Weight is one of the principles of flight. It is the gravitational pull on the object. -
Laws of Motion &. Flight.
Newton's first law of inertia is actually commonly represented by flight. The second law applies to an airplane; it states that "force equals mass times acceleration." The force needed to fly a plane in any kind of direction is equal to the mass! The third law states that for every action, there is an equal and opposite reaction; this applies to wings. They are forced upward because of their tilt, and it pushes air downwards so the wings can be pushed upwards. -
