Air Resistance is a force that opposes the body's motion in free fall. Faster you fall greater the force is. Force Drag Equation is expressed using the formula F = k * v² Where v is the instantaneous speed and k is the air resistance coefficient measured in kg/m . ...
Calculating Air Resistance: Air resistance is usually calculated using the “drag equation”, which determines the force experienced by an object moving through a fluid or gas at relatively large velocity. This can be expressed mathematically as: In this equation,FDrepresents the drag force,pis the...
He used the equation Fnet=m∗a to describe the Second Law of Motion. Rearranging this expression to solve for a: a=Fnet/m, it is easier to see how air resistance represents one of the potential external forces influencing the rate of acceleration of an object. Isaac Newton, the British...
(b) If the projectile rises to a maximum height of only 7.4 m, determine the magnitude of the average force due to air resistance. Homework Equations u + k = u + k The Attempt at a Solution I found the difference in potential energy at m = 7.4 and m = 8.622, which equals the wo...

EXAIRVortex Tubesare constructed from stainless steel. This ensures excellent wear resistance, corrosion resistance and assures years of reliable operation. They are offered in 3 different size ranges (small, medium & large). There are generators located inside the tube (user serviceable) that will ...
2) technical counterseasures for resistance-increasing to control air leakage;and 3) the optimization experiment for inhibitor and the design of fire prevention and extinguish.The result shows that the fracture leading to air leakage is one of the reasons causing spontaneous combustion,and the ...

Atmospheric temperature can be measured with mercury-in-glass thermometers (still used operationally by weather observers), platinum resistance thermometers (PRTs), thermistors, and thermocouples. The last three lend themselves to automatic data logging. PRTs are very stable, and with careful calibration...
I think that air resistance will play a role. You may find the following sites (below) interesting. The one from NASA has some cool animations showing how air flows around a sphere. But inside the barrel, air does not get to flow around the BB, it is getting shoved out the barrel, ...
