Tips To Score Well In Physics

Physics is a subject that deals with the study of the universe from the smallest subatomic particles to the largest galaxies. Physics is a fascinating subject that expands the frontiers of our knowledge of nature helping us understand the world we live in. For a few, being smart at Physics comes naturally whereas for some others it takes some quantity of diligence. Luckily, with determination and perseverance, anyone can master this fascinating science. However, more than obtaining good grades in an exam, the fact that the enhanced understanding of physics will facilitate the understanding of some of the seemingly mysterious forces that govern the manner the world works is what makes learning physics interesting.

While studying a few physics concepts like Photoelectric effect can get tricky, there are a few tips and tricks listed below that can make learning the subject easier and fun. The best way to learn Physics is by approaching it in the right way. Keeping this mind, we have listed a few points that can make the learning process enjoyable.

  • Memorize Basic Constants

Certain forces, in Physics, like the gravitational force on earth, are assigned mathematical constants. This is just another way of saying that these forces are represented as the same number regardless of how or where they are used. It is best to memorize a few common constants as usually they won’t be provided in exams. A few common constants are

Speed of light 3 × 108 meters/second
Gravity on Earth 9.81 meters/second2
Avogadro’s number 6.02 × 1023 per mole
Planck’s Constant 6.63 × 10-34 Joules × seconds
  • Pesky Laws And Equation

Physics is a subject rich in formulae, laws, and equations. One shouldn’t blindly memorize these equations and laws blindly. Always remember that is a low form of learning. Having said this, make sure you can work through the derivation when presented with an equation. The best students in Physics do not merely memorize laws and formulas, rather they understand them. Once you study the laws and formulas at this level, memorization comes easily.

  • Learn Maths Skill Required To Solve Physics Problems

Mathematics is considered as the “language of Physics.” To master solving physics problem one has to become an expert in the fundamentals of Math. Some physics concepts require the application of specialized mathematical skills like (taking integrals and derivatives). Listed below are a few math concepts that are helpful in solving physics problems:

  • Trigonometry (for rotation problems, force diagrams, and angled diagrams)
  • Algebra and Pre-Algebra (for “find the unknown problems and basic equations)
  • Calculus and Pre-Calculus (for taking integrals and derivatives of physics equations)
  • Geometry (Problems dealing with volume, area, etc.)

These were a few tips that will help you study Physics in a better and efficient way. Above all, Keep trying! Everyone learns at different speeds and in different ways.
