the question kasi will lead you to believe na yung conveyor belt is capable of exerting enough frinction on rolling/rotating airplane wheels to stop it from taking off...sabi nga ni niky sa sagot nya..e halos imposible na yun...boy you gonna need trmendous amount of energy to do that..the plane is using its propellers/jet and wings to fly and you are using only friction on its rolling wheels to keep it on the ground?

airplane, rocket pareho lang yan...the only difference is that an airplane needs to be fuel efficient to be able to travel long distances and carry loads at the same time thus the lower speed and use of runway.
