What is the most aerodynamic shape?
teardrop
What are the 4 Forces of Flight?
It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.
What are the three key aerodynamic principles?
There are three basic forces to be considered in aerodynamics: thrust, which moves an airplane forward; drag, which holds it back; and lift, which keeps it airborne. Lift is generally explained by three theories: Bernoulli’s principle, the Coanda effect, and Newton’s third law of motion.
How do you explain aerodynamics to a child?
Aerodynamics means studying how air (or gas) travels around something moving through it. Streamlining to reduce drag in vehicles is a major field in aerodynamics. Aircraft design is another. The study of gases that are not in motion is called aerostatics.
How do you explain a lift to a child?
The lift force, lifting force or simply lift is the sum of all the forces on a body that force it to move perpendicular to the direction of flow. The most common type of lift is that of a wing of an aircraft.
What objects are aerodynamic?
Some technologies that depend on aerodynamics are cars, bicycle racing helmets, wind turbines, and golf balls. Aerodynamics is the way air moves around things. Since air is all around us, there are many examples of aerodynamic technology other than for aircraft.
What makes something aerodynamic?
Aerodynamics is the study of how gases interact with moving bodies. Because the gas that we encounter most is air, aerodynamics is primarily concerned with the forces of drag and lift, which are caused by air passing over and around solid bodies.

Why does air go faster over a wing?
A wing is shaped and tilted so the air moving over it moves faster than the air moving under it. As air speeds up, its pressure goes down. So the faster-moving air above exerts less pressure on the wing than the slower-moving air below. The result is an upward push on the wing—lift!
How are thrust and lift related?
Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure. Thrust is the force that propels a flying machine in the direction of motion. Engines produce thrust.
What is the strongest part of a plane?
landing gear
Is drag equal to thrust?
In level flight, lift equals weight and thrust equals drag when the plane flies at constant velocity. When the thrust becomes greater than the drag, the plane will accelerate forward. If drag becomes greater than the thrust a deceleration will occur.
What happens if thrust equals drag?
When thrust equals drag, the airplane keeps moving at whatever speed it is already moving. Thrust needs to exceed drag in order for the aircraft to accelerate forward. If lift equals weight and thrust equals drag, there is no net outside force acting on the aircraft.
What shape has the most drag?
flat plate
What happens if drag is greater than thrust?
If thrust is greater than drag, the aircraft will speed up, and subsequently, if drag is greater than the thrust, you’ll slow down. Lift is the force that counteracts the weight of an object in order to keep it in the air.
Does Weight Affect drag?
The shape of the object also affects the drag force in two ways. The heavier the weight, the faster the speed of the object (due to gravity), which will lead to the object colliding into more air molecules per second and therefore making the magnitude of the drag force on the object slightly bigger.
How do planes fly with gravity?
Planes do not actually defy gravity, though. Instead, the tilt and area of a plane’s wings manipulate the air particles around the plane, creating a strong enough lift that the force of gravity is overcome by the force of the air beneath the wings.
How do heavy things fly?
Thrust pushes things that are flying. For example, when the thrust force is bigger than the drag force, an airplane speeds up. When the lift force is bigger than the weight force, the airplane goes up faster. When forces are balanced, objects do not accelerate.
