Some excel in the study of physics instinctively! What a wonderful thing that most of us wish to get the final grades in this specialty, it may come back to the genius of this person and Nbugh since childhood in mathematics, but in fact this is not the rule that should be circulated to the rest of the people, most of us harvest the high grades by making an effort It is hard to study and understand. Through this article we will discuss some of the plans and strategies together so that you can achieve excellence in physics with ease.
At first glance, physics seems difficult but it has been proven that knowing basic rules and solving many different questions will change completely with you.
(1) Learn the basic rules of physics
There are some rules and physical constants that are known to every student in this discipline and you will always see them in most books and references , you must know them well - without keeping them! - because you will deal with it a lot during the study and in the dissolution of the exams as you will need them in the proof and answer questions.
For example …
Light speed = 300,000,000 meters per second
Gravity wheel = 9.81 meters per second squared
General hardness of gases = 8.32 gol / (m x Kelvin)
The number of avogadro = 23 ^ 10 × 6.02 per mall
Fixed Planck = 6.62606957 × 10 ^ -34 (G × x)
(2) Know the most famous physical equations
All relations in nature are physical equations, some of which are too simple to be forgotten and the other very complex. Avoid large and difficult equations temporarily and begin to recognize simple equations that represent general rules and rules.
Even complex issues are mathematically proven and solved by these small equations. It will not take you much time to know these equations, and knowing them will help you in the advanced stages.
For example
Speed = distance / time
Wheel = change in speed / change in time
Power = mass × wheel
Kinetic energy = half mass × square velocity
Occupancy = Displacement × Force
Capacity = change in work / change in time
Torque = Mass × Speed
(3) Demonstrate the simplest equations
Saving mathematical equations is not the end. It is a good start to count for you but it is important to know the proof of these equations and to try to prove them yourself. It will take you some time but it will come back later in the journey of excellence in physics and it will make you skilled in your years of study. Coming.
(4) Learn the rules of mathematics
Physics excellence requires a good knowledge of the basics and principles of mathematics. Some call math as the "language of physics" and I call it the "cousin of mathematics." The fact is that they are closely related, being superior in mathematics will become superior in physics.
The most difficult physical questions need math skills and principles to solve, so you should start learning math immediately because this will make you able to handle any question. I recommend you begin by learning the principles of calculus and trigonometry.
(5) Specify the desired in each question
Many physical issues contain some tricks for your dispersion, perhaps in the form of redundant information that will not benefit you in the solution. Try to first identify the information available to you in the question (data) and then know what is needed and start using those data to reach the final output Or proof.
(6) Pay attention to the units of each physical quantity
Forgetting units of measurement is very dangerous to lose you degrees of question, to ensure excellence in physics and to get the final grades in each test should be carefully checked in units in each physical quantity.
Examples of some physical quantities and their units:
Mass: grams or kilograms
Power: Newton
Speed: meters / sec
Power: Gul or kJ
Capacity: Watts
Electric current: amp
Electrical resistance: ohms
Time: Second
(7) Prepare lessons before the lecture
Read the lessons and explanations before the lecture In order to get an overview of the lesson, do not attempt to enter into the details of equations or mathematical evidence; wait until the explanations by the lecturer so as not to become complicated from the beginning!
(8) Be attentive
Gather all your focus during the lecture and follow the moment at the moment all the records, without some notes in your note and always ask for anything you can not understand.
(9) See your lectures at home
After the end of your day, start reviewing your daily lectures at home and work wisely, "Do not postpone today's work to tomorrow," always remember whenever you spend a day studying as hard as you get.
(10) Solve many questions
There is no point in reading the lessons, explanations and theoretical proofs. As long as you are completely away from the application (physical questions), the questions are the practical application of your understanding of physics, solve as much as possible not only to prepare for the exam but also to understand and collect well, Complex!
