right then, a level physics guy coming through.
took me 10 minutes to think of this...
the answer is yes.
lets think about this for a second...
if you were to take the wheels off the plane and accelerate the plane to take off speed.... then add some wheels to it.... and place it on a moving runway at exactly the same seed as the wheels are doing.... wouldnt this be the scenario we have whilst taking off as normal
or on a stationary runway... or even landing... the runway is moving in the opposite direction at ecxatly the same speed as the plane as its conected to the earth...... and the planes doing 300mph+
for all you boffins out there... the resistance of the wheels on the conveyor, "if you will" will allways be less than the thrust from the engines... as the plane is still stationary to the air flow arround it and the eath its in, the plane will move forwards... the thrust is acting on a freewheeling body by pushing or thrusting against air density around the object. again, there would be friction from the wheels, but enough to stop a 20,000lbs thrust plane from taking off.... i dont think so.
theres also the matter of the elastic band powered plane i just put on my uncles treadmill..... if you measure the static speed of the plane, its still static, stationary. if you have any force pushing against it, i-e "thrust" it will move in what ever way there is no resistance.... i-e the fore vector. in other words... lol.....einstien..... every action has an equal and opposite reaction..... if you thrust upon something, unless there is an equal thrust in the opposite direction, then there will be movement......there is no airflow whilst its stood still, but as the jet engine works on air flow, or creating it, there will be an inbalance untill the plane moves as fast as the gasses from the plane....indeed creating flight.
buyeah!:laugh: :laugh:
thus my plane moved off my uncles treadmill...... and that should be the end!
