Let’s look at the absolute best tips that will help you fall in love with Physics immediately!
“Mathematics is the building block of Physics”, very well said by Sir Albert Einstein. In order to understand physics well and to excel at it, you need to build a very strong foundation in maths. At the University of Leeds, in the UK, researchers found how students with better grades in mathematics often did far better in physics than those who did not fare well in this subject! It is a direct relationship and you need to work at it!
Moreover, since a major chunk of Physics questions involve numerical, make sure you perfect fast calculations and number crunching! This will help you out with quick solving! Focus on topics like:
- Pre-algebra and algebra (for basic equations and “find the unknown” problems)
- Trigonometry (for force diagrams, rotation problems, and angled systems)
- Geometry (for problems dealing with area, volume, etc.)
- Precalculus and calculus (for taking derivatives and integrals of physics equations — usually advanced topics)
- Linear algebra (for calculations involving vectors — usually advanced topics).
Refer To Your Common Sense
If you come to look at it, a lot of what physics is is just common sense! The biggest physicists in the world channeled their power of intuition and instinct in coming up with the most profound laws of Physics, and to solve these answers, you need to do the same! Anytime we engage in activities like this, our minds are calculating vectors, force, gravity, and the area under curves. When you’re getting started in physics, trusting your intuition by applying basic common sense can help.
Focus on Conceptual Understanding
More so than most subjects, physics goes beyond simple memorization and review. Of course, studying helps, but physics requires big-picture conceptual thinking. Knowledge in physics is built on a series of conceptual stepping stones—the fundamental principles and laws of the universe—that allow exploration of a huge range of topics. Success in physics depends on a firm knowledge of these basics, and a flexible mind that can assess these rules and determine when and how to apply them to a given problem.
Focus on the fundamentals, but keep the big picture in the back of your mind. Bringing together concepts into a unified understanding of the problem at hand makes finding a solution much easier. Stop beating your head against the wall, and instead use conceptual building blocks to breakthrough.
In Physics, Nothing Is Optional
When it comes to other subjects, you might be in the habit of putting some topics for options and letting them slide, but in Physics, make sure you don’t do this since everything isn’t just crucial…it’s connected. Physics is one of those subjects where falling behind gets you in trouble. This is because it’s generally a series of linked principles that build upon each other. As a subject, physics is more interlinked than most disciplines. In history, if you miss a few lessons, you might not learn about a certain war. In physics, you’re lost for the rest of the course.
Take the time to keep up with assigned readings, practice problems, and homework as the content builds on itself. If you don’t, you’re setting yourself up for trouble!
If you’ve been a fan of the Big Band Theory, you know who Seldon is and you for sure know how he solves complex problems on that whiteboard of his. That’s right- by mand mapping and drawing! A great way to implement the point above is through drawings or graphics. Mind Maps or Mind Mapping enhances our brain’s capacity for memorization through the association of ideas. a Mind Map, unlike other methods of study, involves numerous active cortical skills and helps you to memorize information quickly.
Memorize Basic Equations
In physics, the relationships between the many different forces acting in the universe are described with equations. Some of these equations are very simple, while some are enormously complex. Having the simplest equations memorized and knowing how to use them is critical when tackling both simple and complex problems. Even difficult and confusing problems are often solved by using several simple equations or modifying these simple equations so that they fit new situations. These basic equations are the easiest part of physics to learn, and if you know them well, the odds are that you will at least know some part of every complex problem you face. Just a few of the most important equations are:
- Velocity = Change in position/Change in time (v=dx/dt)
- Acceleration = Change in velocity/Change in time (a=dv/dt)
- Current velocity = Initial velocity + (Acceleration × time) (v=v0+a×t)
- Force = Mass × acceleration (F=m×a)
- Kinetic energy = (1/2)Mass × velocity2 (K=(1/2)m×v)
- Work = Displacement × force (W=d×F)
- Power = Change in work/Change in time (P=dW/dt)
- Momentum = Mass × velocity (p=m×v)
Always Use Correct Units
Silly mistakes can ruin your entire answer! Forgetting to label your answer or using the incorrect units is a sure-fire way to miss easy points. To make sure you get full credit for whatever problem you’re doing, be sure to label your answer with its correct units based on the type of information being expressed. Some of the most commonly-used units for common measurements in physics are listed below — note that, as a general rule, physics problems almost always use metric/SI measurements:
- Mass: Grams or kilograms
- Force: Newtons
- Velocity: meters/second (sometimes kilometers/hour)
- Acceleration meters/second2
- Energy/Work: Joules or kilojoules
- Power: Watts
Solve, Solve, and Solve!
Just like math, writing, or programming, solving physics problems is a mental skill. The more you use this skill, the easier it will become. If you’re struggling with physics, be sure to get plenty of practice solving problems. This will not only prepare you for exams but will help make many concepts clearer as you make your way through the material.
Be sure to solve each and every sum from your NCERT book, and then move on to the next best recommendation!
