## Heliocentric vs Geocentric models of solar system

Credits: ibarabi Observe the above video or GIF. Let’s take a look at what it is about. The GIF is a highly simplified version of Heliocentrism. The planets do not revolve in perfect circles, but in...

## If this doesn’t inspire you to study physics, nothing will.

Recently we came across a video interview of Richard Feynman, one of the greatest physicists of all time. Mr Feynman explores the most basic concepts of physics and expresses them with such depth and vigour....

## All you should know about the pulleys and string mechanics

When it comes to mechanics a very popular problem is the one related to pulley and string. The analysis of pulley string setup is of utmost importance in the study of general physics. Basic Assumptions...

## Gravitation – Physics

From the moment you are born, you experience gravitation. It is such a strong presence that we almost never think of it unless we are taught about it explicitly in the schools. Stop and...

## What is a vector?

While looking for resources on the Internet, we found a fascinating video explaining what exactly is a vector. Check it out here: Video credits: Ted-Ed Vectors are confusing for many students. Every student comes...

## Force of friction explained with a very practical example.

There was a very interesting question I used to ask my friends to show off my knowledge in physics.  Let us see if this excites you to some extent. If a man is walking...

## Motion in a plane

The above image gives the state of motion of the particle at a given time. Can you determine the minimum velocity of the particle? The analysis of the particle will lead us to a...

## Kinematics Studying motion without its cause.

Kinematics is studying the motion of a particle without considering the cause of its motion. We did touch the general properties such as distance, displacement, velocity and acceleration in our previous blog http://edofox.com/blog/physics-motion-in-a-straight-line-2/. Here is a...

## Physics – Motion in a straight line-2

Continued from part 1: The following equation gives the position of the particle $x=4t-t^2$ where $t$ is time in seconds and $x$ is position in meters. Find the distance traveled by the particle in...

## Physics – Motion in a straight line-1

Quick review: We believe you are starting in your journey to study science. Physics would be one of your favorite subjects as you can feel it completely through your day-to- day experiences. It is...
