Tips and tricks are important for getting good scores, passing the competitive examinations. It helps us cut time in solving the problem. This category list various tips and tricks on maths and physics which will be very helpful to the student.
Tips and tricks articles can be used from class 9 to competitive examination
In this article learn how to find acceleration with velocity and distance. We will look at the cases for motion with uniform acceleration and non-uniform acceleration in one dimension. We know that acceleration is defined as a change in velocity per unit time. So given velocities and time, we can calculate acceleration. Now here we […]

Acceleration is defined as change in velocity per unit time. It is a vector quantity and Average acceleration formula is defined as $a = \frac {Final \; velocity – Initial \; velocity}{ time \; taken }$ We will look at steps on how to find acceleration with velocity and time in various situation Uniformly Acceleration Motion

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

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

Right hand rule for cross product:-
Consider that c is the cross product of two vectors a and b i.e.,
c=a x b
If direction of vector a is along the x axis and that of b along z axis then direction of vector c could be find using right hand rule for cross products.

Here in this article we will go through a easy problem showing the basics how to solve the problems where resistors are connected in series and you have to find the equivalent resistance of the circuit. we will do this through an example . For this consider studying the question given below and how I solve this question following several steps. Here our goal will be to analyze few resistors connected in series combination. Further If you want to read the notes related to this topic please follow this link

The Motion problem in Class 9 are limited to Straight line motion with either no acceleration or constant acceleration.
This article 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 Motion for class 9.
Complete Study material has been provided at the below link Study Material
First we need to remember these important terms

Lots of time students me how can they solve physics problems and they say that they are having difficulty in solving physics problems. So here I decided to address this issue. Now first of all I would say that do not be afraid of the subject as I say again and again physics to me is most basic of all sciences and you must find the subject interesting and give yourself reasons for studying it for me it was just what I wanted to study till my masters degree and now I like helping students understanding physics.
