The Acceleration of Gravity and Free-Fall Equations

[@tonyhoward5675]

I should watch more of your presentations. Thank-you.

[@OliyadBekele-u7h]

You sir have to to be the greatest teacher that came after Richard feynman. I went through highschool and now college by the help of your videos thank you.

[@MathAndScience]

This is probably one of the highest compliments anyone can give me, he’s one of my heroes!

[@SajidSahil-l3s]

That is the difference when you watch short video and long like this one.....your concept will be your....but when channel is like this one❤❤❤❤

[@MathAndScience]

Thanks! I’m glad you enjoyed the video.

[@hijadela_BuenaMai7941]

Thanks!

[@MathAndScience]

Wow thank you so much! Many thanks!

[@tresajessygeorge210]

THANK YOU... SIR...!!! I have to review this lecture again to be memorized...!!!

[@drumtwo4seven]

Nice 👍

[@AerialPhotogGuy]

Thank you!

awesoooooooooooooooome

Does a falling object always tends to move towards the centre of the earth?

[@WhiteHenny]

No. Falling objects on Mars tend to move towards the center of Mars for instance. There's nothing special about Earth in that regard. Other factors such as wind can change the direction.

[@gide5489]

The falling direction combines gravity, initial velocity and other secondary effects like Coriolis, etc. So the answer is no, never..

[@raylittle8607]

I always thought objects dropped from a height were in free fall and the reason they contact the ground is because the earth comes up to meet that object at 9.8m/s. 2.

At different times,

[@83jbbentley]

Galileo was so close to many things…

[@tonyhoward5675]

Gives me an idea, a mussing. What if you are a brilliant teacher.

[@hemrajue3434]

I think all objects fall at the same rate in vaccume.

[@felixcat4346]

I'm confused because I thought that acceleration just leveled off at a certain speed so you couldn't go faster in a certain speed when you're falling to the Earth so why is the curve a parabola

[@gide5489]

It is never a parabola

[@WhiteHenny]

Because for the purposes of this video he is ignoring air resistance. In reality the upwards force due to air resistance increases the faster you fall until it balances the downwards force due to gravity. At that point you have reached terminal velocity and will stop accelerating.

[@gide5489]

It is confusing to call g gravity acceleration since the force mg (the weight) exists even without acceleration. Better to call it gravity intensity.

Gravity is not pulling your legs, universe is pushing on your shoulders,
