Flight. Brainstorm. Gravity vs. Drag. Two things affect the descent rate of an object falling through air: Gravity. Wind resistance (drag). These two forces act together, one pulling the object towards the earth, the other slowing it down. Terminal Velocity. Did You Know?
Did You Know?
The terminal velocity for a human being is 200 km/h!
The balance of the two results in a maximum rate of descent.
Lift is the upward force used to overcome gravity and to achieve flight.
1) Bernoulil’s Law of Pressure: The faster air flows, the less pressure it has.
3) Newton’s Third Law: This law says that if there Is a force in one direction, there is an equal force In the opposite direction.
