Hello there! Now we’ll start the topic kinematics. So in kinematics what we’ll basically study is the ways to define motion. So the basic modules that we’ll be studying here in the next few topics is mechanics. So mechanics is divided into two main categories. The first one is the kinematics which we’ll start now.

Energy is available on earth in different forms. These forms are like kinetic energy, potential energy, electrical energy, heat energy etc. We know that a moving object can do work. An object which is moving faster does more work than an object moving relatively slow. Moving bullet, blowing wind, rotating wheel, a speeding stone all

In this video we are going to learn about Newton’s laws. This is the most important topic in whole of physics. Before we start discussion on Newton’s laws, let me tell you two situations where you cannot apply Newton’s laws. First situation when the speed of objects is an appreciable fraction of the speed of

Can you imagine a world where in you’re walking for several hours and you’re not moving or you’re trying to drive a vehicle and it’s not moving. No, we can’t even live in such a way. In fact, we can’t even imagine a world without friction. Because without Friction, you can’t even walk and even

Before we start this lesson, I recommend that you go through the lessons equations for position – time relation and equation for velocity – time relation. In this lesson, we’re going to learn about equation for position – velocity relation. Let’s start by understanding this graph This is a velocity time graph. You can see
