A rocket fired from its launching pad not only picks up speed, but its acceleration also increases significantly as firing continues. Why is this so? (Hint: about 90% of the mass of a newly launched rocket is fuel.)

well, very simply.
The fuel is also adding some weight. The more rocket flys the less fuel (and therefore the less weight) there is. (Especially, when flying straight up at start it loses not only fuel, but the (pretty much) entire bottom.)
Not the answer you are looking for? Search for more explanations.
So the fuel goes out a lot, but not even that. The bottom big peace of the rocket goes off
have you seen a rocket before flight and after it has flown apart from the ground
I have seen a rocket go but I was not that observant.
After the rocket has gone up, it is really not even a rocket.
It is more like a mini rocket after it dropped a big peace at the rise......
They want you to say it is fuel, but I wouldn't focus on fuel as much as on that big falling off piece.
not that I am any relevant to rockets personally, but my grandpa is an engineeer.
How would I relate it to the acceleration?
Oh, the acceleration is more related to fuel (rather than this big falling off peace)....
As fuel is falling out more and more, the more it flies the more the speed increases (due to the fact that the weight it carries decreases).
This increase in speed is acceleration.
thank you :)
What i like better though is to deal with position functions, velocity and acceleration (that are generated at any point x=a, based on the position function).
(this is through differentiation)
Speed tells us how fast the rocket is moving, so speed is the slope of the position of the rocket.
Acceleration tells us how fast the speed is increase/decreasing, so acceleration is the slope of speed.
(if you will)
won't overwhelm..... yw
