AI Thread Summary
The discussion highlights a student's frustration with a grade 11 physics teacher who expresses disdain for the subject and provides minimal assistance while assigning excessive work. The student seeks help with a specific physics problem involving calculating average acceleration from a rollercoaster's speed change. Forum members suggest the student report the teacher's lack of support and emphasize the importance of showing their attempts at solving the problem for effective guidance. Understanding the definition of acceleration is crucial for solving the question. The conversation underscores the need for better teaching practices in physics education.

Bad Physics Teach! :(

Hello all,

I am in grade 11 Physics, and have a question that I need to solve. My teacher has repeatedly said that he hates physice, "I don't want to teach it, and you don't want to learn it", and offers virtually no help, yet assigns massive ammounts of work! I have over 100 questions (in this same format to do), I was wondering if I have an example, someone could walk me through it, so that I can do the rest. I've had many attempts, and every time that I had shown him, he has just said "nono, Look it up in the textbook". Thanks again, Here's the quetion.

A rollercoaster accelerates from 0-160 km/h in 7 seconds. Calculate the average acceleration in:

a) km/h per s


b) m/s(squared)


c) g's (9.8 m/s).

Hi SRForum, and welcome to Physics Forums!

First of all, I think you should report this guy to his boss. He is being paid to do a job.

Second, we do have a requirement here at PF that you show an attempt at the problem (https://www.physicsforums.com/showthread.php?t=28). So if you'd be so kind as to post what you think is the best of your "many attempts", we'd appreciate it. Then we can explain what is going wrong.
 
Every one of those questions depends on knowing the definition of "acceleration". What is it?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
