Discussion Overview

The discussion revolves around the challenges students face in understanding and solving physics problems. Participants share their experiences and strategies related to problem-solving, comprehension of material, and the process of learning in physics. The conversation includes both personal anecdotes and suggestions for improvement.

Discussion Character

  • Exploratory, Debate/contested, Homework-related

Main Points Raised

  • One participant expresses frustration at understanding solutions but struggling to arrive at them independently, seeking recommendations from others.
  • Another participant suggests that reliance on solutions indicates a lack of true understanding and recommends practicing easier problems to build confidence.
  • A different viewpoint argues that some difficult problems may be understood conceptually, but the solution method remains elusive, advocating for persistence in tackling such problems.
  • One participant shares a personal experience of needing to visualize problems, particularly in rigid body dynamics, and emphasizes the importance of practice and seeking help when stuck.
  • Another contributor recalls a professor's saying about understanding material but struggling with problem-solving, reinforcing the idea that practice is essential for developing problem-solving skills.

Areas of Agreement / Disagreement

Participants generally agree on the importance of practice and the challenges of understanding physics problems. However, there are differing views on the implications of needing to see solutions and the nature of problem-solving difficulties, indicating that the discussion remains unresolved.

Contextual Notes

Some participants mention specific types of problems, like those involving rigid bodies, as particularly challenging, highlighting the variability in individual experiences with different topics in physics.

i don't know what's wrong with me, but i almost always completely understand a problem once i see its solution, but without the solution, i don't get very far with it. has anybody else had this problem? if so, what do you recommend?
 
Physics news on Phys.org
I've seen this many times. It means, I'm afraid, that you don't really understand the material. Following someone else's solution is not the same as understanding it yourself, just like watching other people exercise won't make you stronger.

The thing to do is to work more problems. If you don't know where to start, work a series of easier problems until you have them down cold. Then go back to the problem that is giving you trouble. If your textbook doesn't have enough problems (and it may not), get them from another text on the same subject.
 
I'm not so sure about that. The hardest problems are the ones where you completely understand what's going on, but you just can't see the trick to solve it. In that case you just have to keep banging your head against the wall and attacking the problem from all angles until it concedes.

I have the same problem!

=(
 
thanks all for your input.
maze, i agree with you there, after looking at the solution i always think duh...thats so obvious,why didn't i think of that. I also agree Vanadium because i guess if i truly understand the material, I'd know exactly what angle to attack the problem from.

i welcome any other opinions concerning this
 
I recommend you to do the maximum number of exercises you can without giving up early. If you're really stuck on a problem, post it here in the homework section. Helpers will lead you into the right direction without giving you the answer and you should be able to solve the problem almost by yourself.
For me very hard exercises are exercises I don't understand what's going on. When I can't imagine the problem... for example problems related to the rigid body. Sometimes I don't know how will evolves the system, so I really have to imagine the situation and "guess" how the masses will move. Sometimes I must ask to someone else what's going on and from it I try to solve the problem which generally is not that easy for me. And looking at the answer won't help me in most cases. (unless the problem is obvious and I didn't succeed in solving it).
So do a lot of exercises and you'll realize that many are of the same kind. You should be able to solve almost every kind of problems after a good training which implies doing well at exams.:smile:
 
My sainted physics 101 professor (RIP) had a sign in his office that read:
"I really understand the material. I just can't do the problems."
A refrain heard all too many times.

As Vanadium 50 advised, the solution is to seek out and solve as many problems as possible. Beware the crutch of prematurely "peeking at the solution"--it's very easy to delude yourself into thinking you understand something when you don't. Only if you struggle on your own will you develop the confidence to solve problems.
