Physics is a subject which arouses tremendous zest in some enthusiastic minds. There are others who get horrified by the very word. The thought of studying this subject sends a chill down their spine. No matter what category you belong to, you need to learn it. It is an integral part of curriculum and can help you get good scores, if you master it well.
Physics in daily life
This discipline is all about matter and energy. When I say that there is no life without physics, there is no exaggeration. The principles of physics are used in every walk of life.
- Electricity is the wonderful gift of physics without which our life would become miserable.
- We all do health check-ups and remain fit. It is the principles of physics that are used in machines for X-rays, blood pressure,
- Can you imagine the world without vehicles? This has also been possible because of physical principles.
- From telephones to e-mails, we owe every means of communication to this wonderful field of science.
What is classical physics?
The term ‘classical physics’ is used to describe the theories developed in the ancient times i.e. before 1900s. Modern physics describes the inventions and theories formed after 1900s. Classical physics deals with matter and energy on a larger scale without plunging into complex studies of quanta. It does not use theories of quantum mechanics.
But sometimes these theories are insufficient to explain extremely small objects such as atoms. Newton’s mechanics and thermodynamics are part of classical study. Classical theories are used in situations where modern physical theories make matters unnecessarily complex.
Misconceptions prevalent about learning physics
There are several prejudices among students about physics.
- It is mostly considered to be suited for the ‘brainy ‘This is absolutely wrong. You don’t need to possess very high IQ levels to become confident in this stream.
- Problems are always considered to be tough. It is true that there are lots of problems to be solved in physics. But they can be learned through practice.
- Most students perceive physics as a time consuming and difficult subject. This is true to an extent. But proper understanding of the subject makes your task easier.
Seven ways to master classical physics
- Understand basic concepts properly:
Classical physics might look easy as compared to tougher topics in quantum physics. Students have the tendency to go easy on classic theories. Unless your basics are strong, you will not be able to grasp difficult topics. Before jumping into black holes, your laws of inertia need to be perfect. So be thorough with them. For example, while learning Newton’s laws of motion, try to apply these in real life situations. Don’t try to memorize facts without understanding them.
- Memorize formulae and equations:
Study of physics is incomplete without formulae and equations. Some equations are simple and easy to learn whereas some others are too lengthy and tough. Learn the easy ones and know how to derive the complex ones. Also, learn the applications of equations. A good base in equations will help you solve problem-based questions in exams. As compared to modern physics, the intricate concepts are less in the classical theories. For this reason, formulae are also easy on brain.
- Experiment more and practice more:
The best way to learn physics is through experiments. Do some simple real life experiments to see whether your understanding of concepts is correct. The benefit of this method is that you memorize better. Once you do a hands-on experiment, you will never forget the concept. Practicing problems is as important as learning. There is nothing as ‘too much’ when it comes to practice. Do again and again until you feel that it is impossible to make a mistake.
- Make use of diagram and graphs:
As physics has a lot abstract concepts, drawing on paper gives a better idea of facts. Moreover, it is a proven that our brain has the capacity to retain visual images more than simple text. Draw simple diagrams or graphs to learn better. When faced with a tough problem, draw it out using the given facts. Analyze the relation between the given elements. Use arrows or markings and then try to arrive at solutions. This approach is very helpful while practicing for exams.
- Take online help:
With the advent of latest technological innovations, learning is now at your fingertips. There are several study help websites like ours, which offer you guidance in every field of study. Whatever be the subject, physics, maths or biology, help is available. Attend to video lectures of hard portions. Watch videos of various experiments and try to do them on your own. Learning by doing is the best way. Do the practice problems given in sites. Make use of technology and stand a step ahead of your peers.
- Form study groups and discussion forums:
Discussing in groups is the most effective way to clear your mind. Form a group of like-minded friends who are interested in learning physics. Discuss all concepts with them. One interesting fact worth mentioning is that when you explain a concept to someone, you get a better clarity yourself. So explain your ideas to them as well as listen to their ideas. You can even do experiments together and make it enjoyable. So join groups and combine learning with fun.
- Strengthen maths skills:
It is well-known that physics is a problem-solving subject. There are several mathematical principles used in physics problems.This makes it essential for you to have good mathematics and problem-solving skills. If your maths is good, half work is done. No physics student can ignore maths. A combined approach to maths and physics can help you excel. You cannot afford to love physics and hate maths. Both go hand in hand.
All the above-mentioned factors will help you become an adept in physics, provided you are ready to put in best efforts. Give your best and rest assured that you have a shining future waiting for you.
