How Will You Solve the Problems Quickly in Physics?

by Nov 1, 2015Physics

When it comes to solving problems in Physics, the biggest issue is not a lack of scientific or mathematical knowledge required for doing calculations. Rather, a problem arises from a lack of proper experience or a fear of how to begin solving the problem. It can also arise due to an improper approach in handling problems or even with the studying itself. If you are baffled about your physics problems and wondering where to start, keep in mind that there is a logical process to solving these issues. Use of the following proper techniques will guide you through various issues, allow you to effectively communicate your answers and solve your physics problems much faster.

Go through the question

1. First of all, you need to read question in a proper manner. Some of the solutions can come easily when you carefully read question at first. It is a good idea to translate all things provided in the question into a mathematical format and then define the variables that are needed immediately.

2. Go through the problem or question as many times as you would need in order to know exactly what you should do in every section.

3. Think whether or not the same average quantity should come up in varied calculations.

4. If this does not happen, you should only replace the numerical values into algebraic expressions.

Draw diagrams

You should also draw numerous diagrams of a situation that has been discussed in the question, so as to make a situation completely clear in your head and your solutions easily understandable. Frequently, a single diagram is sufficient. You should not use values but only symbols in your diagrams. Close to your illustration, draw a table comprising of all the givens so that the units and precision mentioned in a question or problem statement is handled well. By drawing diagrams, you can visualize the problem more easily. This can be particularly assistive in clearing any symmetry which is relevant.

Separate the suitable components

When it comes to force problems, you should separate the suitable components of your system. Use them to draw a force diagram and place a system of coordinates on each diagram. Calculate the suitable equations of movement. In other types of problems, show the suitable relations and laws and justify the equations that you derive where they are needed. Make sure that define all the symbols that you use, either in an explicit way or through context.

Outline the formula

Outline a formula and complete the algebra with the help of symbols. In case you do not find any values to be provided, use dimensional analysis to check the formula. Where you find values to be supplied, replace them in a formula and ensure that the units and precision have been respected. Check value that is asked for. Round off answer to an approximate value on which result depends.

Solve for the variables

In case you find out the ways to solve the problem first with variables, you will always find it easy to return and put in the numbers. In case you exclusively solve with the help of numbers, you will put yourself at risk of making mistakes. Keep it in mind that while variables are precise, numbers are not.

Explain the reasoning

While calculating a mathematical problem, you should keep it in mind that you should explain reasoning. At times, it can be tough to decipher your actions only from mathematical computations. This can make it tough for you to get even partial marking in case you make some mistake that is as basic as a sign error.

Look for a sensible answer

Finally, you need to ask yourself whether or not an answer actually makes some sense. If you do not find any physical sense from the results, you should check your calculation again. Make sure that the formula is showing the right dependencies as far as the given is concerned. Complete your solution in an appropriate manner and clearly state answer in precise units. Never let the solution die down. Ensure that the person who will be checking your paper will be satisfied with the result and that you have done as asked for and reached the end point of your result.

Do not make conversions unnecessarily

If there is no need to make conversions, it is better not to do so. In case problem shows the length of something in inches and another one in meters, it is a good idea to convert them all into meters. However, there is no need to do so if you find all lengths to be provided in inches. You can keep your results in the form of inches. There is no need to do any conversions. For instance, if you find two lengths to be provided in inches then final answer would be based just on the ratio of lengths. In such a case, a ratio will be the same whether you keep the lengths in meters or in inches in a ratio. While performing the conversions, you are always at risk of making errors. There will be no risks of such errors if you do not convert.

Ask for help

In case you find it tough to solve problems, it is never a good idea to keep struggling in silence. Ask your professors, fellow students or a friend and get assistance that you require. You can get varied perspectives and easier solutions from them, which can give you an altogether different point of view about your problems. Follow line of reasoning that they apply and attempt to find out the areas where you are lacking and reason behind the lag. Once you are able to do that, you can improve your skills easily.

Last but not the least, keep on trying and never give up. The more you invest time and the better you practice, a better you will be able to improve yourself and find your physics problems not so difficult anymore.
