## Force of friction equation (friction formula)

In this article learn about force of friction equation (or friction formula). This friction formula is very important while solving problems related to Newton’s laws of motion. You may also like to go to class 11 physics notes for more notes and study materials. Force of friction is a force which acts between two surfaces in contact and when one surface slides on the other … Continue reading Force of friction equation (friction formula) »

## 10 common mistake in Examination

1) Panicking Before Or During A Paper: Always prepare for a test or exam well in advance.Have a good night’s sleep before the date of the test or exam.Keep reassuring yourself that you can do it. Once you stop doubting yourself, you will stop panicking. If all else fails, comfort yourself that it is only a paper. It’s not the end of the world even if you don’t do well for just one paper.So just relax and Do some breathing exercise to relax

2.Failing To Scan Through The Questions Once: Do not immediately start answer the first question. Give yourself about 5 minutes to read through all the questions. Put a tick against the easy questions and a cross against the difficult ones. Then, proceed to answer the easy questions first! Always leave the difficult questions to the last. This ensures that you would have answered most of the questions in the paper should you run out of time. It also gives you more time for the difficult questions, as you would need relatively less time for the easy ones

## 10 things you can do to improve your memory for math formulas

1. Read ahead – Prepare for Tomorrows today.Read over tomorrow’s math lesson today. Get a general idea about the new formulas in advance.As you read ahead, you will recognize some of it, and other parts will be brand new.This technique also gives you an overview of the diagrams, graphs and vocabulary in the new section. Look up any new words in a dictionary so you reduce this stumbling block in class. This step may only take 15 minutes or so before each class, but will make a huge difference to your understanding of the math you are studying.

## Conservative and Non conservative forces

Some Points about Conservative forces and Non conservative forces
1) Potential energy are defined for Conservative forces
2) An object that starts at a given point and return to the same point,then
net workdone by the conservative force is zero while in case of non conservative force ,it will not be zero

## Thermodynamics Problem solving tips

Net Heat flow at a junction is Zero
Internal Energy does not depend on the path
Internal Energy in a cyclic Process is zero
Workdone is given by the area enclosed by the process on the PV diagram
Always make sure you Heat(Q) ,Internal Energy(U) and Work(W) with correct sign in equation

## How to apply law of conservation of energy in mechanics

We often comes across the problems in mechanics where we need to apply the law of conservation of energy where gravitational potential energy or gravity is involved . For solving such problems you can consider the following problem solving strategy,

## Acceleration formula Explained with Examples

Acceleration Formula Acceleration is the rate of change of velocity with time. It is a measure of the change in the velocity of an object per unit time and mathematically acceleration formula  is given as For describing average acceleration, we first consider the motion of an object along a straight line. Suppose at time t1 object is at point P moving with velocity v1 and at time t2 it … Continue reading Acceleration formula Explained with Examples »
