Being good at physics comes naturally to some lucky individuals.It takes a lot of hard work to get a good grade in physics.Almost anyone can master their physics material by learning and practicing important skills.A better understanding of physics may shed light on some of the seemingly mysterious forces that govern the way the world works.
Step 1: Basic constants should be memorised.
The force of gravity is assigned mathematical constants in physics.This is a fancy way of saying that the forces are usually represented as the same number regardless of where they are used.Most of the time, the most common constants won't be provided on tests, so it's a good idea to memorize them.Speed of light: 3 10 meters/second Molar gas constant and Avogadro's number are some of the most frequently used constants in physics.
Step 2: Understand basic equations.
Equations describe the relationships between the many different forces in the universe.Some of the equations are very simple.When tackling simple and complex problems, it's important to know how to use the simplest equations.Simple equations are often used to solve difficult and confusing problems.The easiest part of physics to learn is the basic equations, and if you know them well, you will know a lot of what you need to know.Change in position/Change in time is one of the most important equations.
Step 3: The basic equations can be studied.
Understanding why the equations work is more important than having your equations memorised.Take time to learn how each basic physics equation is derived.This will help you understand the relationship between the equations and will make you a more versatile problem-solver.If you understand how the equation works, you'll be able to use it more effectively than if you just memorize it.Let's look at a very simple equation: Delta(v)/Delta(t)The force that causes an object to change is called acceleration.The object can be said to accelerate as it changes from v0 to v, but it won't be instantaneous.Thus, a Delta(v)/Delta(t).
Step 4: It is necessary to learn the math skills to do physics problems.
It is said that math is the language of physics.You can improve your ability to master physics problems by becoming an expert in the basics of math.Special mathematical skills like taking derivatives and integrals are needed to solve complex physics equations.There are a few math topics that can help you perform physics problems in order of complexity.Precalculus and calculus are used for taking derivatives and integrals of physics equations.
Step 5: Every problem should have important information in it.
Red herrings are information that isn't needed to solve the problem.Determine what you are trying to solve for when you read a physics problem.Write the equation you need to solve the problem, then assign each piece of information to the appropriate variables.Ignore information that isn't needed, as this can slow you down and make finding the solution more difficult.As the car's speed changes over two seconds, we need to find out how fast it is.The standard acceleration equation shows that v0 is 9 m/s and v is 22 m3/s.This doesn't take the object's mass into account, so we can ignore the fact that the car is over 1,000 lbs.We would solve it as follows.
Step 6: Every problem can be solved with the correct units.
It's a sure-fire way to miss easy points if you don't label your answer or use the incorrect units.To make sure you get credit for your work, be sure to label your answer with the correct units based on the type of information being used.As a general rule, physics problems almost always use metric/SI measurements, and some of the most commonly-used units are listed below.
Step 7: Don't forget the small details.
).A physics problem is a model of a real-world situation that makes it easier to understand.Sometimes, this means that forces that can change the outcome of a problem are left out.This is not always the case.If these minor details aren't explicitly left out of the problem and you have enough information to account for them in your answer, be sure to include them.A problem will ask you to find the rate that a 5 kilogram wooden block will accelerate along a smooth floor if pushed with a force of 50 newtons.The answer may seem simple since F is m a.The force of friction will affect the forward motion of the object, reducing the force it's being pushed with.Leaving this out of the problem will result in an answer that is slightly faster than it would be.
Step 8: You should double-check your answers.
A physics problem can easily involve a dozen or so calculations.If you have time, you can double-check your answer at the end to make sure your math adds up.One way to check your math is to re-do your work, but you may also want to use common sense to relate your problem to real life as a way of checking your answer.You wouldn't expect a negative answer if you were trying to find the mass velocity of an object moving in the opposite direction.If you get a negative answer, you probably made an error in your calculations somewhere along the line.
Step 9: Before the lecture, read the topic.
New physics concepts should be avoided for the first time in class.Try to read upcoming lessons in your textbook the day before class.At this stage, focus on grasping the general concepts and trying to understand what is being said.You'll be able to apply the mathematical skills you learn in class if you have a solid foundation of knowledge.
Step 10: During class, pay attention.
During class, the teacher will explain the concepts you encountered in your pre-reading and clarify any areas of the material that you don't understand.Take notes and ask questions.The mathematics of the topic will be covered by your teacher.If you don't remember the exact derivations of each equation, try to have a general idea of what's happening.Talk to your teacher if you have questions after class.If you want to show the teacher that you were listening, make your questions specific.If the teacher isn't busy, she or he will be able to schedule an appointment to go over the material with you and help you understand it.You could ask your professor or teacher if they would allow you to record the lectures so that you can listen to them later.You can ask for clarification after listening to the lecture again.
Step 11: You can review your notes at home.
As soon as you have a chance at home, take a few moments to go over your notes and polish your physics knowledge.Doing this will help you keep up with what you've learned.The longer you wait to review your notes, the harder it will be to remember them and the more foreign they will seem.
Step 12: Practice questions can be solved.
Solving physics problems is a mental skill.The skill will become easier as you use it more.It's important to get plenty of practice solving problems if you're struggling with physics.This will prepare you for the exams and make many concepts clearer as you progress through the material.Don't be content to use the problems in your homework for practice if you're not happy with your grade in physics.Problems in your textbook that aren't assigned to you, free problems online, or even problems in physics practice books can all be solved with an extra effort.
Step 13: You can use the sources of help.
There are a lot of ways to get help if you have a difficult physics course.Use any help resources you can find to get a better understanding of physics.Most students have at least a few free options when it comes to help resources.If you need physics help, there are a few options: your teacher, your friends, a tutor, or third-party resources.
