    Ap Test
AI Thread Summary
To succeed on the Physics B AP Test, it's crucial to study diligently, especially if previous instruction was lacking. Creating a cheat sheet with important formulas can help reinforce understanding and identify areas of weakness. This process not only aids in memorization but also makes studying less daunting. Self-motivation is essential, as relying solely on the teacher for drive can lead to failure. Maintaining a positive mindset can significantly impact performance, as expectations influence outcomes.

hey everyone, its been a while since I've been on the board, i have my physics B ap test coming up in less then a month and i was just wondering if anyone has any advice.. i don't know how good i'll do, i love physics but my teacher was terrible. thanks

study hard bro!
 
Oh dear god your going ot fail unless you study like there's no tomorrow. And i say this because of the TERRIBLE TEACHER part. I had a terrible teacher for the B class and we all failed I am pretty sure. All we did was shoot off rockets and sleep and the test came at us like a ton of bricks. We had people that the next year went off to Caltech and Berkeley and a few to MIT that i truly think didnt pass that test because the teacher didnt motivate us at all.
 
Peng: okay, I'd just like to comment that it is not the teacher's responsibility to motivate a class. It is his responsibility to facilitate learning, which he may have failed to do, but not provide your drive. If you are in an AP class and are not self-motivated, you are going to fail the test on your own merit.

However, back to the subject. sarnis, I think you should try this... Go about the test as though your teacher just gave your the ability to take a cheat sheet into the test with you. Actually make a sheet of all the formulas you are most afraid will come up or that you are not sure of. Then, once that is made, study that sheet and make sure you can use any of them just from memory (what each symbol means, the units, the formula itself).

The whole process of making the cumulative cheat sheet will get you thinking about your strengths and weaknesses so that you can address them for the test. Also, it usually doesn't take to long to deal with and makes the whole process a lot less intimidating. And of course, if any of those formulas give your problems, you will be able to come onto this board and get help with that specific question!
 
Oh yeah, and finally... Think positive. Studies show that if you expect to do well, you do much better than if you expect to fail. You rise to your own expectations, in a way.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
