Air Resistance Formula Air resistance is a force that affects objects that move through the air. Often physics problems used in teaching ignore it, but it is very important for understanding the motion of fast-moving objects like airplanes. It depends on the density of the air, the area of ...

Air Resistance Activities In the absence of air (no air resistance), all things fall with the same acceleration due to gravity; this is Newtons's Second Law. In real life, there is air resistance. We will explore the variables of the force of air resistance in some simple experiments. ...

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 density of the fluid,vis...
1、Likewise, the ball physics will be subtly different; the ball will fly a bit faster and straighter since there is less air resistance.(同样,球物理学会微妙的不同,球将飞更快一点,更直,因为有较少的空气阻力。) 2、Air resistance must be given carefully consideration when the aircraft is to...
1 Reducing air resistance In practice there are several ways of reducing air friction on a moving vehicle. Figure 2 shows some examples.a What ways of reducing air friction are shown in Figure 2? Can you think of some other ways?b What hypotheses can you make concerning the factors that ...
