Air Pressure
14.69 pounds per square inch (psi). 2,115.36 pounds per square foot. 19,038.24 pounds per square yard. 58,972,852,224 pounds per square mile. If you want to calculate the complete gravitational force of Earth, find the area (in square miles) and multiply it by 58,972,852,224. That will give you, in pounds, the complete gravitational force of Earth.
Air resistance is a contact force because you are in contact with the air in order to apply that force.
The force exerted by the kids to pull the rope up and down would increase. The motion would not be fluid (you wouldn't get a perfect harmonic wave). You're amplitude might change if the kids weren't able to exert the proper amount of force.
Whenever any object moves through air (eg an aeroplane) it observes four forces 1 Drag force 2. lift force 3.weight of object 4.thrust created by the propellers or engine of the object. The drag force is directed opposite to the direction of moment of the object and slows the object down.
It's the gravitational effect of the Sun combined with the inertia of the planets. Their inertia (Newton's first law of motion) would make the planets move in straight lines, but the gravitational force makes them follow elliptical paths and they orbit the Sun.

Air Pressure The force exerted by the air above is called?
The force exerted by air in all directions is called air pressure. It is caused by the collisions of air molecules with surfaces. Air pressure is exerted equally in all directions and decreases as altitude increases.

drag force (frictional force exerted by air) or air reststance
The air pressure is exerted in the direction of the air flow. But this is subjected to the Boyle's law. So Boyle's law is correct. You have add the force exerted by the speed of the air to it.
