Expert Tips for Solving Physics Problems | Ace Your Finals in 6 Days!

In summary, the student is preparing for their physics final exam. They have studied a lot, but their teacher recently told them that they may struggle with solving difficult problems on the exam. The student is seeking general advice on how to approach these types of problems. Some suggestions given include reviewing past tests and quizzes, studying with fellow students, and utilizing online resources such as Khan Academy. The student's teacher may be suggesting that they need to understand the reasoning behind formulas and how to apply them in more complex problems. It is recommended that the student also consult a student review book for additional help in understanding physics problems.

Hello everyone! My finals in physics are in the corner (actually in 6 days) and I have studied a lot. Tho, my teacher yesterday told me that in the exams, unfortunately, I won't be able to make the hard thought or solve the hard problem. And that almost 1 week before just took me apart. And ok I am stupid got it and yes now it's too late. But, could you give me any general advice on how to solve physics problems?

My suggestion would be to go back through your tests, quizzes, and problems looking for the areas you had the most trouble or greatest trouble and then look for Khan Academy videos related to the topic to review it.

I would also study with your fellow students to see if they can help you as they went through the same course and know better what the teacher will test on.

This is really the best you can hope for this late in the game.

I'm sorry, I don't understand why this is a problem for you. My students would have been happy if they didn't have to solve hard problems on exams. :biggrin:

Thank you!

Yes um like sometimes in some exercises you have to understand things about what is going on in order to order to solve them. So he kinda told me that I can't put the things down and think them in order to solve the hard problems

Wow, you're fast! You answered the first version of my question before I changed it. :smile:

I still don't understand the problem. :frown: Maybe there's a language difference. A specific example might help.

Can you describe a concrete example of a problem you have difficulty with?

So far your descriptions are too fuzzy and hence we can’t give good advice.

For high school physics problems, there are formulas you need to know and the conditions that these formula apply under.

Yeah sorry about that, just it's the language difference and don't know exactly how you do things there to be honest. So I can't really give an example but I will try. We have an exercise with oscillations. I know the formulas I have read the exercise and have used the formulas in the first 3 questions. The 4th one is harder and it needs to think in order to solve in and not just use the formulas. He said, that I cannot make that "hard thought" that is required to solve the question. Even though I know the formulas

So your teacher is telling you that you don’t have the ability to solve the fourth problem?

He’s saying you’re not smart enough to solve it?

Or is he saying you need to think more deeply about?

i really wish you could give us a concrete example because we just can’t help if we can’t identify what you’re having trouble ith.

I know many students have trouble applying the correct physics formula from a list of formulas to a given problem. They don’t know the condition under which a formula applies.

In college, you learn to derive the formulas from the conditions of the problem and then you begin to see how things are interconnected.

He says I am not too smart to solve it. Because even though I know the formulas I can't think around them in order to solve something different than the classic problems

Okay then you need to review those Khan videos that should help you.

And talk to your fellow students about this. Your teacher is trying to point out that you need to understand the reason behind why one formula is used over another or how you can work through a more complex problem by finding intermediate values and applying the formulas in a certain sequence to achieve your answer.

Do you have a student review book that you can refer to? Often they will point out where students have difficulty in understanding.

Remember physics problems are more than just simple algebra problems. They need some physical insight and common sense to solve.

If you look at enough past papers, you soon realize that certain questions (in different disguises) appear very regularly. Learn how to answer those questions and to recognise the common basic patterns of the questions. You have to answer the questions on your own first - without peeking - and only look for the answers when you genuinely cannot think how to do them. I can only speak for typical UK exam questions but you need to realize that the Exam Board actually wants you to be able to answer the question and they often take you through a number of clear steps (a mark for each) towards the final answer. Use that guidance and do not try it totally on your own. That could possibly be boring but just go for the marks and don't ask why they are doing it 'that way'.
 

What are the steps to solving a physics problem?

The first step is to clearly identify what is given and what is being asked in the problem. Then, list all relevant equations and constants. Next, plug in the given values into the appropriate equation and solve for the unknown variable. Finally, check your answer for reasonableness and accuracy.

How do I approach a complex physics problem?

Start by breaking the problem down into smaller, more manageable parts. Identify what is known and what is unknown in each part. Then, use the appropriate equations and principles to solve each part. Finally, combine all of the individual solutions to arrive at the final answer.

What should I do if I get stuck on a physics problem?

If you are stuck on a problem, take a step back and review the concepts and principles related to the problem. Look for similar examples or practice problems to gain a better understanding. If necessary, seek help from a teacher or tutor.

How can I improve my problem-solving skills in physics?

Practice is key to improving problem-solving skills in physics. Work through a variety of problems, starting with simpler ones and gradually increasing in difficulty. Make sure to thoroughly understand the concepts and principles behind each problem, rather than just memorizing equations.

What resources are available to help me with solving physics problems?

There are many resources available to help with solving physics problems, including textbooks, online tutorials, and practice problems. Your teacher or professor can also provide guidance and assistance. Additionally, forming study groups with peers can be beneficial in problem-solving and understanding difficult concepts.
