## Physics Homework Help: A Strategy for Solving Physics Homework Problems

Many students need help getting started on the problems of physics homework. Here is a general strategy that can be applied to many types of physics homework problems.

For many students, the hardest part of a physics class starts solving problems. If you want to succeed in physics, you learn to solve problems. This article describes a basic problem solving strategy. It is designed for physical problems, but can also be applied to problems in other areas such as physics, especially for homework in other sciences, natural sciences and mathematics. Try it. The textbooks are often too specific strategies for certain classes of problems.

• Hide your calculator: Most students begin their first calculators and punching numbers. No !!!!!!! Save this for the last step, after you know the numbers of Punch.
• Description: Please read the problem, look for keywords. Make sure you understand what it takes. Distinguish between relevant and irrelevant information. Translate the problem with your own words. List of all information in the problem, explicit and implicit, and the desired information.
• Display: Draw a picture of the situation. If the issue is a motion for a diagram showing the positions of the movement, speed and acceleration to draw. If the problem is a strength, draw a free body diagram of forces. A problem of the collision pulling objects before and after the collision, and so on. Do this carefully and get all relevant information. Make sure you care for details, such as explicitly defining your coordinate axis, positive direction, and zero points for such information to remember and use them consistently throughout the problem.
• Solution qualitative (no numbers): Translating the problem of English words that are equivalent to physical principles. What principles are involved? For many people, this translation is so difficult a problem. The work on this topic. Also a proposal for the final solution or the basic form of the solution. This proposal should be based on previous experience or physical intuition. Why do you think is the basic form of the solution?
• Planning: Selecting the equations governing this problem, taking into account the physical principles involved in the final stage. Describe how the basic equations use the information given to the desired information. Except in the simplest problems, the data to the desired information, it takes a number of steps, but if the procedure correctly describe the problem is essentially solved. If all else fails and you’re clueless about how to proceed, write all the equations governing this problem. Make sure that the demand equations and the known quantities to see what you can learn to fill. This is not the ideal approach, but it is named for solving problems is a total loss.
• Solution: Enter the plan. Solve the problem algebraically first, where possible, an algebraic solution of the problem to obtain. Finally, the last step taken in the figures and numerical calculations to perform. Now you can get your calculator. If you’ve done the above steps correctly, the real solution to the problem is quite simple.
• Verification: Make sure you correct all the previous steps. Think about the answer. Does it make sense physically? Otherwise, why not write (especially on a test) and recheck all previous steps. A check is fast enough to do is to check whether the units. If the units are not entitled to work, you’ve done something wrong. Check all previous steps. Then review individual cases. Often the solution to a given case is already known from personal experience. Check if your solution works for these specific cases. What happens when a variable is zero, infinity, etc.? Another variable? Checking the answer in the back of the book can be useful, but it’s not because: 1) You will not always be the “backbone”. and 2) The solutions may be unreliable.

Other measures to be used as needed:

• Persistent: If the problem does not work the first ten times, try again. If you persist long enough, you can solve most problems. Relatively few problems can be solved at once, without much experience.
• Something else for a while: this is not a license to goof off. However, something else when working on a difficult problem do for some time. While you are doing something else, or relax, work on another subject, or whatever, your subconscious mind is churning. When you return to the problem, you will often (not always) see something that you do not understand.

If you understand the problem of writing assignments that demonstrate your work carefully. This will improve your grade.
