I’m sure at one point in time we all have stayed up all night memorizing physics formulas. A lot of students assume just looking at the problems, it’s in their mind, but the next day shocked to apprehend the formulas have perished the night before. The formulas keep pulling you back to your old books instead of moving on. Physics has this aura that scares people before they even start solving a problem. Physics explores the motion of birds, trundles, planets, lightning, and empty space itself!

Sometimes it requires a Mathematical and Conceptual thought and understanding that is way much advanced as describing our world is not at all times intuitive. In Physics each component is represented by an element symbol. The first letter of the name is capitalized in English, Latin, or German. Example:

  • H – Helium
  • W – Wolfram (tungsten in German)
  • Sn – Stannum (tin in Latin)

When you look at your Exam questions the sentences arise scarily, confusing you to no end. Students have no idea where to start, in spite of recognizing the basic theories. What sort of wave travels on the string? What numbers of waves pass a given point per second? Whose vehicles go in which direction? Electricity? Magnetism? Don’t Panic. It isn’t necessary to understand all the small details, but once you know in general what is being dealt with, you will know to formulate answers and understand to use the right equation.

Mentioned below are a few formulas that are used often:

Formula
Explanation
 s = $\frac{d}{t}$ Speed = $\frac{distance}{time}$.

Average speed = total distance / total time.
(m/s or cm/s)
 v = $\frac{d}{t}$ Velocity= $\frac{displacement}{time}$.

(m/s + direction)
 F = ma Newton's 2nd Law; the force on an object is equal to the product of its mass and acceleration.
(Newtons (N))
 Ek = $\frac{1}{2}$ mv$^2$  Kinetic Energy; energy of motion = $\frac{1}{2}$ $\times$ mass $\times$ velocity$^2$.
(Joules (J))
Momentum = mass $\times$ velocity  
m is the mass and v is the velocity

Learning formulas is not a one-day gimmick. Conceptual understanding of a formula makes it easier to remember. It’s best to understand the formulas instead of just trying to memorize it. Create funny prompts and reminders such as rhymes, songs, story or phrases to remember the formula that are difficult to remember otherwise. The more you solve problems based on a formula, more are the chances that you will remember it for years. Repeated exercises and problem solving is the only way to strengthen memorization. Memory exercises, repeatedly done and constantly, will etch these formulas in a student’s mind forever.

Steps to solve a Problem:
  1. Understand the Situation
  2. Read the Question Carefully
  3. Organize the Information
  4. Sketch the Scene
  5. Consider Your Formulas
  6. Solve and Verify results

The way to recognize which equation to use depends on two main issues: the variables given to you in the equation and practice. The more problems are solved, the more you will become accustomed to picking the right formula.
