Inertia & Newton's First Law of Motion - [1-5-4]

In this lesson, you will learn what inertia and how it applies to Newton's first law of motion. Newton's first law states that an object at rest will tend to stay at rest unless acted upon an outside force. Additionally, an object in motion will tend to stay in motion unless also acted upon by an outside force. These ideas form the core foundation of physics in that they are the basis upon which we describe the motion of an object. Other phenomena are also reliant on motion such as thermal energy and wave mechanics, and are dependent on the idea of inertia and newton's laws of motion.

This is the most under rated teacher in the world. He should be awarded teacher of the decade.

I started watching you to learn about a triangle, but now I find myself wanting to learn so much more about Physics. I can remember when I was young, my dad talking about some of these concepts. Your teaching style is second to none. Thank you very much.

[simongozah]

God created you to teach learners until death....don't stop teaching...you inspire me a lot with your actions and analogies when you teach...I know even your blood teach when you are asleep...waw great

When one meditates upon it deeply enough, it begins to dawn on one that, even absent mathematics, Newton's First Law is fundamentally quite profound--not only profound, but also poetic and beautiful.

I wish you were my teacher. I love watching your videos. I always understand what you're saying, unlike my physics teacher at school. I hope you can teach us about Newton's other laws of motion. Thank you so much!

What a beautiful, super-lucid lecture making us see how counter-intuitive, i.e. how contrary to the expectations of the conventional mind Physics is! Thank you for helping us understand how Physics can expand our minds and overall view of the world, that it can be a thrilling journey and an excellent means for spiritual nourishment. Greetings and gratitude from Athens, Greece.

Good physics concepts with a solid background of calculus. applause 💥❤

Awesome teacher! I love listening and learning from you. You have a special talent! God bless!

Excellent Sir, so happy to correct ourselves.

1:35 Except that it isn't Newton's law, it is Galileo's.

This is Newton's 1st law:
"Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon."
- The Mathematical Principles of Natural Philosophy (1846) by Isaac Newton, translated by Andrew Motte
Axioms, or Laws of Motion


Origins of the 1st law:
"The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes. Before Galileo it had been thought that all horizontal motion required a direct cause, but Galileo deduced from his experiments that a body in motion would remain in motion unless a force (such as friction) caused it to come to rest. The law of inertia was deduced by Galileo from his experiments with balls rolling down inclined planes."

There is no state of rest. A force is always acting on something. Only the level of force changes.

[KavuzweMichePatience-usvd]

nice thank you but idont get it very well but thank you wish i will get nice marks in my test👍💝thankyou byeeee

[roselineclement]

I just know physic and understand it in just some minutes, thank you sir

[patod]

Actually the opposite of what Aristotle said, objects on Earth want to rest.

[SummerSun-li]

Excellent video and Teacher, thank you very much.

[agajafarli]

Wouldn't shooting the ball out of the cannon accelerate it as opposed to giving it a constant velocity?

[TheParanormalPathfinder]

That was explained so well I feel that I have wasted my life. lol

[yesuishka]

I’m a 6th grader and this is kinda hard understand but I learned a lot!! Thanks teacher

[raymondallenjhangiani]

Beautifully explained ! Thank you 🙏 Sir !

[hitendragadhavi]

Wonder full teaching skill.
Plz.. Keep up donot stop it
