So when there are few days left for your board exams , you might be thinking how to do well in physics Board exams or how do you memorise your physics formulas so that you can write all the answers that are asked in your exams easily. It is important to memorise physics formulas for exams because memorising them will increase your speed and by the end of the time you will be able to complete all your questions and still have time to revise and check for the mistakes in all of your paper.
Introduction to physics project for class 12 physics investigatory projects for class 12 carry 3 Marks in the Final Examination. Let us take a took at some important concept What is Science: Our knowledge of the natural world and the process through which that knowledge is built The process of science involves many layers of complexity, but the key points of that process are straightforward.There are … Continue reading Physics project for class 12
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
In this article I would discuss what are free body diagrams and how to make one. Free body digrams are of immense importance when one want to study physics. You will find great deal of their usage while studying mechanics and tou can hey have equal inportance when it comes to other branches of physics. However i will discuss their usage and construction in context to mechanics.
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
This mathematics sheet would be helpful for quick revision of most of maths formulas needed before class 11 and 12 physics examination. It covers quick and much needed formulas on differentiation , integration, trigonometry, AP, GP etc.
This tour is given to give the feel of the whole chapters plus the type of questions and ways to tackle them.This is quite beneficial for anybody studying One dimensional Motion.
One dimensional Motion is the study of the motion along an straight line.Complete Study material has been provided at the below link
