What you'll learn

Test your understanding of everything listed below using Udemy quizzes and Assignment features (to truly master the concepts)
1. Explain what 1D motion is
2. Differentiate between distance & displacement, speed & velocity using very simple words
3. Calculate average values of speed and velocity (for particles moving in straight line) without having to memorise formulae
4. Differentiate, clearly, between average velocity and instantaneous velocity (Usually a topic of confusion)
5. Explain clearly what acceleration means (you will be able to explain why top speed isn't the only thing that matters in sports cars)
6. Calculate acceleration when velocities are changing without having to memorise formulae6.
7. Differentiate between uniform and non - uniform motion
8. Draw x-t, v-t and a-t graphs for various uniform and non-uniform motion. (Graphs will no longer look abstract)
9. Analyse x-t, v-t, and a-t graphs to extract informations about position, velocity and accelerations.
10. Derive the most important SUVAT equations from graphs and identify general strategy to solve any problem on uniformly accelerated motion.
11. Solve variety of numerical problems on uniformly accelerated motion using the SUVAT equations (Most important takeaway of this course)
12. Explain the concrete meaning of differentiation and integration to someone (The essence of calculus).
13. Figure out the rules of differentiation and integration logically (This is unique, as most introductory courses just state the rules of calculus without any logic or explanation)
14. Understand what position functions and velocity functions are
15. Using differentiation, calculate instantaneous speeds and accelerations for non uniform motion. (from position and velocity functions)
16. Using integrals, calculate area under curves, velocities and positions for non uniform motion.(from velocity functions)
17. Explain why differentiation represents slopes and integration, area under graphs.
18. Explain the characteristics of a projectile motion
19. Solve numerical problems on projectile motion.
20. Explain, intuitively, why velocity is a relative concept.
21. Understand what reference frames are.
22. Calculating velocity of an object from different reference frames mentally. (This skill is especially important for solving some tricky problems in physics)
23. Solve tedious looking problems with few steps by changing reference frames
24. Be ready to learn higher concepts of motion in 2 dimensions.

Introduction3:32

Distance, Displacement4:22
This first video explains, the most basic concept about motion.
Distance and Displacement.
Test Your Understanding about Distance and Displacement
Average Speed and Average Velocity8:46
Test Your Understanding about Average Speed and Velocity
Example On Average Speed and Average Velocity7:39
In this video, we will solve a numerical to apply our knowledge of distances and speeds
Example on Average Speed and Average Velocity 25:55
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
Average speed & average velocity summary
A mind map summary of Average speed and average velocities

Instantaneous Speed ?7:44
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.
Instantaneous Speed Demo6:49
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.
Defining Instantaneous Speed and Instantaneous Velocity7:58
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
Understanding Instantaneous Speed and Instantaneous Velocity

Who will win?3:05
Can you guess who would win?
And the Answer is (Understanding Acceleration)3:55
And here is the solution!
Defining Acceleration11:08
Now that we have a solid intuition behind, what acceleration is, we will go ahead and define it in this video
Understanding Direction of acceleration7:19
This video is exclusively about figuring out the direction of the acceleration
Another example of direction of acceleration2:46
Test your understanding of Acceleration
Acceleration Simple Numericals7:36

Position Function and Average velocity7:35
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
Understanding Position functions and Average Velocities
Position Function and Instantaneous Velocity10:33
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
Understanding position functions and Instant velocities
Instantaneous velocity at any time t07:33
We will be smart now, and figure out the velocity at some random moment of time to
Calculating velocity at t0
Differentiation of t power n5:46
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
Understanding derivative of t power n
Example Numerical (Calculating Average Speed)10:31

Requirements

No prior physics knowledge required. (We will start from scratch).
All concepts can be understood intuitively without any (or hardly any) math.
Basic algebra (Like "x + 10 = 25, find x") for solving numerical problems.
Calculator or calculator app (Optional).
A pen/pencil and a book/pieces of paper to solve assignment and quiz problems.

Description

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)

Who this course is for:

If you are absolute beginner in physics or you are already taking a course but want to understand the subject deeply.
If you don't like to just memorise equations but understand where they come from and how to use them.
If you find problem solving in 1D motion hard, this course is highly recommended.
If you are high school student, this course is very highly recommended.
