How to Physics Formulas can be Memorized
Memorizing formulas is a bit tricky when a NEET aspirant knows that the syllabus is very vast. It’s become very difficult for NEET aspirants to memorize each and every formula. If formulas are of physics, this means NEET Aspirants should remember all the formulas at their fingertips. This only can happen when NEET Aspirants solve problems by applying formulas in it. Memorizing formulas is a bit tricky when a NEET aspirant knows that the syllabus is very vast. It’s become very difficult for NEET aspirants to memorize each and every formula
NEET Physics includes a lot of formulas which really needed to practice and memorize. There may be a few general reasons like lack of concentration (focus), less time and too much to grasp, or difficulty in relating which formula is used for which problem. Working on such issues is the priority; else aspirants may end up forgetting some really important formulas. NEET Aspirants must know one thing for sure, that all formulas are important and easy to master.
There are some steps which NEET Aspirants have to follow while practising or solving the NEET Physics formulas:-
- Scan Through and Familiarize
In NEET Physics, there are variables which are repeated, like ‘r’ or ‘R’ is used for radius and it is common in most of the formulas. So first make a list and study which variable is for what, this is how you get familiar with them. NEET Aspirants should simply scan through them. Use the formulas in the numerical and solve them. Do not simply mug up.
- Apply the Formula and practice the questions,
Practising will help NEET Aspirants learn to apply the formulas in the right manner and in the right sequence at the same time. When an aspirant solves problems based on a formula in this way, aspirants will understand how to use it and where to use which formula, and continuous practice of solving problems becomes easy for NEET preparation for NEET 2020. - Learn to Derive Formulas, NEET Aspirants cannot memorize hundreds of formulas in NEET Physics together. The best way to memorize the formulas is to “Derive the Formulas”. There are some formulas which are derived from the other formulas this process makes memorizing very easy. A shortlist of formulas in the circular motion chapter or any other chapter in Physics will help you derive many other formulas as shown below:
- a. d (diameter of the circle in meters(m)) = 2r ( is the radius of the circle in m)b. v (is the speed of motion in m/s) = ωrc. a (magnitude of the acceleration of motion in m/s2)= ωvd. ω (angular frequency s-1) = 2πfe. T (length of time of a revolution in seconds) =1/f (number of revolutions per unit time in s-1 /Hz)f. C (circumference of the circle in m) = 2πrFor example,
v = ωr and a=ωv
can give you the relation between a and r
a=ω2r so from two basic formulas you can derive another formula which you need not memorize.
- Understanding the Structure and Units of Formula
Consider, a= F/m
Here the force is on the top as you need force to move the object quickly so it has an upper hand while mass has to be moved with a force so you need force to accelerate the mass.
Whereas, a=m/F has an upper hand but remember without force an object cannot move so it cannot be possible that mass is on the top. So there has to be something wrong with the formula.
Units:
Again, a= F/m
The unit of acceleration is a=m/s2 (since a =vω, ω =1/s and v=m/s ∴ a=m/s2)
So when you solve the units of F and m you must get the unit of acceleration.
Now, F is force and m is for mass of an object;
F=kg.m/s2 or Newton and m (mass) =kg
So when you substitute in a,
a= (F/m) =(kg.m/kg.s2) = m/s2
This is the structure and the units of formula, aspirants can follow this way or any other way to memorize the formulas in NEET Physics. It’s an easier way to understand the physics formulas.
Take Notes
NEET Aspirants can also try to make notes with the important formulas and stick them up on their wall or cupboard or just beside the mirror. This will help aspirants glance through and not forget the formulas easily in the NEET examination. Revise the formulas each and every day.
Visualize and Test Yourself
NEET aspirants should try to test them and visualize their performance. For example: Take a couple of questions and try to use formulas in these questions, without seeing and solving them. If the answer is correct, aspirants succeed, if not, try again and test yourself and visualize your potential and ability to solve the problems in the preparation for NEET 2020.
These are some ways to memorize the physics formula for the NEET examination. NEET Aspirants follow these ways in their NEET preparation and crack NEET 2020. The best and the easiest way to memorize formulas are to practice them by solving more and more questions thoroughly and sincerely, Practicing questions on daily basis can only help in memorization of all the NEET Physics formulas.
