All waves can be classified into two kinds: transverse waves, and longitudinal waves.water waves, light waves, rope waves and radio waves are the examples of transverse waves, while sound waves and waves which are produced from vertical oscillating spring under tension are few examples of longitudinal waves. Now! Stay with us to know the examples of transverse and longitudinal waves ...

What is Kirchhoff’s Voltage Law? Kirchhoff’s voltage law is a fundamental circuit law that states that the algebraic sum of all the voltages around a closed path is zero or, in other words,the sum of the voltage drops equals the total source voltage. Kirchhoff’s loop rule In an electric circuit, the voltages across the resistors(voltage drops) always have polarities opposite ...

Electric potential definition “Electric potential at a point in electric field is the amount of work done to bring the unit positive charge from infinity to that point.” The gravitational potential at point in the gravitational field is the gravitational potential energy of a unit mass placed at that point.In this way ,the electric potential at any point in the ...

Fundamental forces of nature Difference between conservative and non conservative forces Frictional forces What is Force? “A force moves or tends to move,stops or tends to stop the motion of object.The force can also change the direction of motion of an object.”It can also change the shape or size of a body on which it acts. In classical physics real ...

What is Rectification? Conversion of alternating current into direct current is called rectification. Semiconductor diodes are extensively used for this purpose. How many types of rectification ? There are three common types of rectification: Half wave rectification Full wave rectification Full Wave Bridge Rectification Voltage multipliers rectification Half Wave Rectification An alternating voltage of Time period T is called input ...

Basic forces of nature physics The man has always desired to comprehend the complexity of nature in terms of as few elementary concepts as possible. Among its quest, in Feynman’s words,has been the one for “wheel within wheels”, the task of Natural Philosophy being to discover the innermost wheels if any such exits. A second quest has concentrated itself with ...

Read More »## Difference between gravitational force and electrostatic force

Gravitational force is the force by which earth attracts other objects by mass.It is a conservative force.While electrostatic force is the force of an object due to charge.It is also conservative force.These two forces belong to the four fundamental forces of nature. Now! We see the difference between gravitational force and electric force in tabular form. Gravitational force Vs Electric ...

The angle between two vectors is referred as a single point, known as the shortest angle by which we have to move around one of the two given vectors towards the position of codirectional with another vector.It is found by using the definition of the dot product of two vectors. How to find Angle between two vectors? We can find the ...

What is the Gravitational field? “The space around the earth in which earth can exert a force of attraction on other bodies is called gravitational field.”A basic fact of the gravitation is that to particles exerts forces on one another.This is a direct interaction between the two particles and is called the action at a distance because the two particles ...
