Name three situations in which force is created. describe the cause the cause of the force in each situation.

There are four aerodynamic forces affecting an airplane while in flight, they are 1.Lift 2. Weight 3.Thrust 4. Drag. Lift is cause by different wind velocity under and over an airfoil shape of the wing of an airplane. According to Bernoulli's principle as velocity increases pressure decreases, as velocity decreases pressure increases. This pressure difference create a force known as "Lift". Weight is the downward force cause by gravitational force exerted by earth on an airplane. Thrust is a forward force created by combustion engine usually cause by the expansion of gases as it passes through the nozzle of an engine. Drag force is opposite of thrust, cause by friction air on the body and surface of an airplane

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4

It may possibly be c i think |-/
