| 1332915 | 2013-03-16 02:37:00 | Now most people know the physics question of "jet on a a treadmill" where one has a jet on a treadmill which exactly matches the wheel speed etc etc. It goes on, I'm sure you all know. If you don't just google it. Now one question I always think of is, will the wheels on the jet actually turn? If the treadmill EXACTLY matches the wheel speed at all times will the wheels ever start moving? My initial instinct is to say no because for the wheels to turn in the first place, one thing has to be moving faster than the other to start with. What are your thoughts on this? I do have a feeling they can start turning but I still kinda think that shey shouldn't. |

| 1332918 | 2013-03-16 02:55:00 | I think I have made a fool of myself with this question haven't I :p | The Error Guy (14052) | ||

| 1332920 | 2013-03-16 03:17:00 | It is standard procedure for this test :) (We take turns.) | R2x1 (4628) | ||
| 1332921 | 2013-03-16 03:45:00 | It won't be the first time or last time for me either :D | The Error Guy (14052) | ||
| 1332922 | 2013-03-18 01:43:00 | If the treadmill matches the velocity of the plane the wheels will not turn | BBCmicro (15761) | ||
| 1332923 | 2013-03-18 02:07:00 | Of course the wheels will still turn to enable the plane to stay still on the treadmill, if they didn't turn the plane would get carried in the direction the treadmill is going | gary67 (56) | ||
| 1332924 | 2013-03-18 02:42:00 | In the experiment, you start with a jet on a treadmill. Very shortly after that you just have a treadmill. And yes, the wheels were probably spinning pretty fast as the jet took off (at the rotational equivalent of the ground speed of the jet + the treadmill speed if I'm not mistaken). | pablo d (15490) | ||
