Mechanics

There are four fundamental forces in nature which we experience every day:- The strong force The weak force The gravitational force The electromagnetic force These four fundamental forces govern everything that happens in the universe. What is gravitational force? According…

In this article, we will learn how to calculate distance from acceleration and velocity. We would consider a special case of motion where our object under consideration is moving with constant acceleration. Here in this article, we will only discuss the…

In this article, we will derive the second equation of motion by graphical method. Let us first explain the second equation of motion. It is the equation that relates the displacement of the object moving under constant acceleration. In this…

In this article, we will derive the first equation of motion by graphical method. The formula for the first equation of motion The first equation of motion is given by the relation  \(v=u+at\)  Where  $v$= final velocity$u$= initial velocity$a$= acceleration$s$=…

Here in this article, we will derive the third equation of motion by graphical method. This equation relates initial and final velocity with acceleration and displacement. While solving problems you must remember that these equations can only be used when…

Let us learn how to find displacement on a velocity-time graph. This is one of the core graphical tools used to describe how objects move and change position over time, and it builds directly on the vector quantity described in…

Average velocity is defined as the displacement divided by the time during with the change in position of the particle takes place. Average velocity is a vector quantity and its SI unit is meter per second \((m/s)\). So,\[v_{avg}=\frac{\Delta \vec{x}}{\Delta t}=\frac{x_2-x_1}{t_2 -t_1}\]Consider…
