Relativity?

how come when you are driving and a plane is coming in for a landing and it looks like it is not moving and really it is going like 200 mph i know it is called relativity but why?|||Because you consider near objects, like tall trees as motionless backgroung. They are not motionless with respect to you, thought, that's why you wrongly perceive the airplaine as motionless, or even flying backwards.





Try to use remote objects as background reference: distant clouds, or the sun, to name a few, and illuision will disappear.|||Actually this is not relativity.





Relativity is the relationship of space and time and the dialation of two different objects.








What you are talking about is actually simple geometry.





Often people gauge the speed of an object on the rotation of their head, the change in this angle is seen as the important factor.





Let's say something makes your head move 30 degrees in 10 seconds at 10 feet away





Let's say something makes your head move 30 degrees in 50 seconds at 100 feet away.





([30/360]*2pi * 10)/10 seconds = The Radial motion in the distance (Assumed it's a radial motion)





([30/360]*2pi*100)/50 seconds = The Radial motion in the distance (Assumed it's a radial motion)








The angular velocity will be higher in the first situation than the second. However the physical distance traveled of the object will be higher in the second. If your brain assumes angular motion with high velocity, the plane seems slow.|||you should be watching the road.|||because sence you are also moving in comparison to your location it does not appear to be moving
