What happens to your body when you fly on an airplane?
Air pressure is lower at higher altitudes, which means your body takes in less oxygen. Airlines “pressurize” the air in the cabin, but not to sea-level pressures, so there’s still less oxygen getting to your body when you fly, which can make you feel drained or even short of breath.
Why is physics so important in flying airplanes?
The physics of flight requires that lift, drag, weight, and thrust happen at the correct time and in the proper amounts. For an airplane to go up into the air, the lift has to be stronger than the force of gravity. Lift happens at the wings as air passes over them.
How does this physics principle apply to airplanes?
The faster an airplane moves, the more lift there is. When the force of lift is greater than the force of gravity, the airplane is able to fly, and because of thrust, the airplane is able to move forward in flight. According to Newton’s third law of motion, the action of the wings moving through the air creates lift.
Why do we do lazy eights?
The lazy eight is a maneuver designed to develop perfect coordination of controls through a wide range of airspeeds and altitudes so that certain accuracy points are reached with planned attitude and airspeed.
Why is my plane not flying as well as it should?
If your plane is not flying as well as you think it should, or once did, you need to make some adjustments both on the ground and in the air to get the plane back to peak performance. Simple things like center of gravity and amount of movement in the elevons need to be correct for your plane to fly well.
Why do some Paper Planes fly better than others?
Some paper planes clearly fly better than others. But why is this? One factor is the kind of design used to build the plane. In this activity, you will get to build a paper plane and change its basic design to see how this affects its flight.
What happens when forces are not balanced in a plane?
When the forces are not balanced, flying objects speed up, slow down or change direction. This is called acceleration. 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.
What happens when you throw a plane in the air?
When you throw a paper plane in the air, you are giving the plane a push to move forward. That push is a type of force called thrust. While the plane is flying forward, air is moving over and under the wings and is providing a force called lift to the plane.
