Three years ago I explained how to use photographs to estimate the speed of a passing car. You can read that article at https://physbang.com/2020/08/02/keep-the-cogs-turning/. Now it is time to use a similar technique to answer a more challenging question: what is the take-off velocity of a passenger jet? Of course, the answer could be found … Continue reading Aircraft take-off velocity
Resultant Forces (part 3)
In the final part of this mini-series, we have to deal with situations where the two component forces are neither opposite nor at right angles; the forces are simply at some general angle to each other. Typical situations where this could apply in real life are tugs pulling a ship or an airplane flying through … Continue reading Resultant Forces (part 3)
Flight facts
How long do you think it takes to get to cruising altitude on a long-haul flight? Aircraft travel has become so smooth that you could be forgiven for thinking that within 20 minutes, at the most, you're in level flight. And you would probably also think that the aircraft's speed is fairly constant from about … Continue reading Flight facts
