We use almost all greek alphabets to represent various physical quantities and units in physics. The purpose of this article is to look at the meaning of Omega Symbol in physics. Omega Symbol Omega is the 24th and last letter of the Greek alphabet. It stood for a long “o” sound in Ancient Greek. It still stands […]

## What is Velocity time graph?

Velocity vs Time graph This article is about the velocity-time graph. Before going further details of the topic let us first understand how to draw these graphs. To draw graphs in x-y- plane The independent variable is always taken on the x-axis. We plot the dependent variable on the y-axis. The dependent variable is dependent […]

## Dimension of permittivity in Vacuum or free space

Dimensional Formula of Permittivity with its Derivation In this article, we will find the dimension of permittivity in Vacuum or free space. Dimensional formula for absolute electrical permittivity of free space is We would now derive this dimensional formula. Derivation for expression of Dimension of permittivity From Coulomb’s Law, electrical force acting between two charges […]

## Horizontal projectile motion : Derivation and formula

Horizontally launched projectile concept, formula, and derivation In this article, we will learn about horizontal projectile motion. In this case, the projectile is launched or fired parallel to horizontal. So, it starts with a horizontal initial velocity, some height ‘h’ and no vertical velocity. I am assuming that you know about the basic concepts of […]

## Range of projectile formula derivation

Horizontal range of projectile formula derivation This article is about the range of projectile formula derivation. I have tried to make it as easy as possible but you need to know a few basics of projectile motion to get a clear idea. This is an important topic that involves Motion in a plane with Constant […]

## What is Position Time Graph?

This article is about the position-time graph. Before going further details of the topic let us first understand how to draw these graphs. To draw graphs in x-y- plane Independent variable is always taken on the x-axis. We plot the dependent variable on the y-axis. The dependent variable is dependent on the independent variable through […]

## Types of motion in Physics

Types Of Motion In Physics In this article, we will learn about the types of motion. There are four basic types of motion namely 1. Translational motion- Motion along a straight line or motion along a curved path. 2. Rotational motion- It is motion about a fixed axis for the example Ferris wheel. 3. Periodic […]

## what is trajectory

what is trajectory A trajectory is the path followed by an object with mass in curvilinear motion (curved path) as a function of time. Mathematically ,It is defined by the equation in x-y coordinates. A famous example would be projectile motion like the ball thrown an angle or a bullet fired from gun. Here the […]
