The 4 Forces of Flight
By: Kaia Bloye
Force 2: Weight and Gravity
Weight is a force caused by the gravitational relationship with earth. Humans are more aware of weight because we have weight and see it every day, we can measure our weight on a bathroom scale but this type of weight is way different and can not be measured by a bathroom scale its measured by a spring scale or a hydraulic or pneumatic scale. Gravity holds all objects to the ground.the lift, lifts an airplane up and the gravity makes a balance and hold the plane in place.
Force 3: Thrust
Thrust is a force described by newtons second and third law. The newtons principal is the universal gravitation states that any two bodies attract to each other with a force. Thrust is when a system expels or accelerates mass in the same direction. The accelerated mass will cause a force of equal magnitude, but opposite direction of a system.
Force 2: Drag
Drag is a mechanical force generated by solid moving through air. In this case an aircraft. How is drag generated you may ask. Drag is generated by interaction ( wings and air) and contact (aircraft in the air.) It is not generated by a force field like it is in the avengers. Drag holds you back and thrust (the opposite) pushes you forwards.
