This course is all about Kinematics in 1D, the physics of moving things along a straight line. Kinematics is always the first topic you would have to master in order to understand the laws of the universe. Everything in the universe is moving, so kinematics is the most fundamental thing you will need to know to do any kind of physics.
I expect no prior knowledge of physics, in order for you to take this course. The only pre requisites are little bit of math (mentioned in the course basics). Although kinematics needs calculus, I will be teaching everything calculus that we will be needed to tackle various scenarios. So don't worry about calculus :)
The course is structured as follows
Concept videos, Practice problem videos, Extra information (Which is not mandatory but helps you get more insight and get more out of the course :))
For every concept, I have included trivial and challenging quizzes to make sure, you can check your understanding and review any material if needed.
There are assignment questions which test your application abilities and how you are able to connect various topics together.
At the end you have practice test, with timings and scores. This makes you self evaluate your learning and understand how much you have gained from the entire course.
So what are you waiting for, enrol and let's get.. wait for it... moving! (sorry for that, my jokes get better)
This first video explains, the most basic concept about motion.
Distance and Displacement.
Test your understanding of Distance, Displacement, Speed and Velocity
In this video, we will solve a numerical to apply our knowledge of distances and speeds
This is a classic problem. Here is an example of why sometimes people find physics difficult. Because it tends to contradict with our intuition. The problem arises when we don't have the right intuition, or when we don't understand a concept thoroughly. This video clears out some misconception about average values in general.
And you will get a chance to check your intuition by solving an assignment below
This is going to blow your mind away. Here we will define, something that seems paradoxical. We will figure out how to conceptualise speed at a particular moment in time.
To get some intuition behind instant speed. Let's do a demo shall we? Here we will calculate the speed of the ball just before it hits the ground.
Let's learn some notations that we use to denote instant speed and velocity. Also you need to figure out something by the end of this video, and let me know your thoughts on the assignment question below
Can you guess who would win?
And here is the solution!
Now that we have a solid intuition behind, what acceleration is, we will go ahead and define it in this video
This video is exclusively about figuring out the direction of the acceleration
In this episode, we will look at a mathematical way of representing motion using a position function. Once we understand position function, we will learn to calculate average velocity from it
Find average velocity
Now that we have a position function, we should be able to calculate (for the very first time) instant velocities and speeds. I will teach you how, in this episode
Practice the art of calculating instantaneous velocity
We will be smart now, and figure out the velocity at some random moment of time to
You will calculate instant velocity at t0 for two functions. Ready? GO!
We don't want to keep calculating the velocity, manually right? So once we generalise, we can use the formula to evaluate velocities and speeds for most functions
Let's just see how much you have grasped from the previous episode
Let's check your understanding of Uniform Motion
Check your understanding
Let's have a quick check of your UAM understanding
Which of the following represents the correct equation for the displacement? (the symbols are defined in the previous video)
Hello there, I am Mahesh Shenoy, but you can call me Mashy
I am basically an electronics engineer, but I shifted branches from applied electronics to pure science - namely physics about 4 years ago. My passion for physics grew watching the famous Walter Lewin lectures on youtube, and I always had a thing for teaching. As a student I know exactly what makes lectures boring, and uninteresting. I have dedicated past few years to master physics and teaching. I would say I am quite pleased with where I stand
Whether you will be able to master concepts of physics, is something that only you can decide. I can promise you, if you hear me out, I ll make you love physics. I ll make you see physics in your everyday world, and your life will never remain the same!
