How to increase our interest in chemistry and physics?

Try to Visualize all the concepts in Physics and try to solve more and more problems ,then you will get confidence in the particular topics . Try to solve HC VERMA and NCERT must be on your tips .

For chemistry try to solve whole NCERT for Organic try to solve MS Chouhan ,for for inorganic Narendra Awasthi then try to memorize the reactions in organic and interest will be generated automatically .

Memorize basic constants. In physics, certain forces, like the accelerating force of gravity on earth, are assigned mathematical constants.[1] This is simply a fancy way of saying that these forces are usually represented as the same number regardless of where or how theyâ€™re used. Itâ€™s a smart idea to memorize the most common constants (and their units) â€” often, they wonâ€™t be provided on tests. Below are a few of the most frequently-used constants in physics:

Gravity (on earth): 9.81 meters/second2

Speed of light: 3 Ă— 108 meters/second

Molar gas constant: 8.32 Joules/(mole Ă— Kelvin)

Avogadroâ€™s number: 6.02 Ă— 1023 per mole

Planckâ€™s Constant: 6.63 Ă— 10-34 Joules Ă— seconds

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:[2]

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 Ă— time) (v=v0+aĂ—t)

Force = Mass Ă— acceleration (F=mĂ—a)

Kinetic energy = (1/2)Mass Ă— velocity2 (K=(1/2)mĂ—v)

Work = Displacement Ă— force (W=dĂ—F)

Power = Change in work/Change in time (P=dW/dt)

Momentum = Mass Ă— velocity (p=mĂ—v)

Hey to increase the increase the interest in any subject you have to learn concepts from basics properly and then relate every advance concept with the basics of chapter for example - In Newtonâ€™s laws of motion the very basic concept is F=ma now try to relate every concept whether itâ€™s spring mass problem,constraint motion try to relate it with basics i.e F=ma then you will surely develop intrest in subject.

First of all, you need to believe that â€śscoring good marksâ€ť and â€śbeing able to solve numericalsâ€ť are not necessarily the factors which help you develop interests in any subject (not just Physics).

Scoring good marks, solving numericals and all other academic stuff which we do, have nothing much to do with developing interest in particular subject.

For that, all you need to have is passion and curiosity. If you have it then it will become easier.

Look around, there are many things (in fact, everything) happening around you involve some Physics. Ask question to yourself, â€śwhy is it happening?â€ť, â€śwhy this, why not this?â€ť. Keep asking questions from you. Find the explanation of what you see. First try to answer by yourself. If you are able to answer that move to the next question. If couldnâ€™t then donâ€™t give up. Keep trying.

Find people who may have the answers. One most important thing is, donâ€™t just get the answers from them and leave. Discuss it with them. Figure out, why wasnâ€™t you able to answer it earlier? Did you know the required basic concepts for that question? Were you able to use those concepts for answering the questions? If not then find the answers of that too. Now if you didnâ€™t know those basic concepts then now is the time to go for books.

Find a good book, learn those topics and then try to answer it again. First learn the concepts then do MUST derive the formulas (then only you will be able to implement it in your numerical questions or in practical life situation). Now you will be able to answer it. Keep a practice of the above method. After some time you will find some Pattern in answering questions. You will find that almost all the questions are inter-related.

Hope it answers your question.

Last but not least, donâ€™t just try to mug-up the theories and formulas to answer/solve question, Learn it. Do not take it as work otherwise it will become boring. Enjoy it!!!

And once you achieved that, help others if you can.

All the best. Cheers!!!
