Tips and tricks articles can be used from class 9 to competitive examination

How to find acceleration with velocity and distance

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 […]

how to find acceleration with velocity and time

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

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

Problem solving tricks-Right hand rules (Magnetic fields due to currents)

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.

How to study physics and solve problems?

First thing which student should do before doing the physics Problems is the study of the chapter and concepts Studying the Chapter and Concepts (1) Attend all the classes in School and understand whatever the teacher is saying about the chapter. (2) Take good notes and develop the concept. (3) When you copy drawings, completeness

How to solve resistor in series problems

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 .
