I wish you were my teacher. you explain everything so well. I am actually understanding what you teach. I still have problems analysing the equations and solving them, nothing that a bit of practise won't solve. thank you for making this page.
I'll be using your physics principles for determining forces acting on safety harnesses in my own videos. I just needed a refresher. As a scaffolder, I find it important to know these principles and use WEIGHT and MASS, when free falling wearing a safety harness
Your videos are remarkable sir:))). Thank you, now I'm not having a hard time answering physics problems because of your impressive teachings. Thank you.
Thank you for posting this, I just discovered your channel and it’s just gold. I know that you’re selling video courses. When I had enough money I’ll make sure to buy them. I’m big supporter of “free education” but the work you’re doing is important and it deserves to be paid.
@@MathAndScience WHY E=MC2 IS NECESSARILY AND CLEARLY F=MA ON BALANCE: Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. C4 is the proof of the fact that E=mc2 IS F=ma ON BALANCE. This explains the fourth dimension.

Thanks so much for your time and effort ! A question : If gravity is because of curb. of space-time and there is no Force to grab things so why after realesing an objct from a distance above Earth it falls Down towards the center of Earth no mater where on Earth it is dropped and why after casting an object opwards then it Will not stand still when it reaches the highest point when velocity becomes zero ? Thanks !
Sir, I have a question. In using the acceleration due to gravity, does the sign always depend on the direction of the object? For example, if the object moves downward, use (+9.8) and if it moves upward use (-9.8). Or if the formula already uses positive, you could use -9.8 and vice versa?
no down is negative look at a x/y chart at origin it's zero zero so down Y is negative, and up is positive [and left is neg. X while right is Pos. X so gravity/is down; so negative. Planets may vary in the magnitude but down is neg. and up is positive; this guy is excellent
How do you aply this to gravity with respect to starting distance to find the velocity at the ending destance. This equasion should not include time, just distance from object. I can not use the equasion “square root of 2gh” because that is implying that the stringth of gravity is constant and does not change with respect to distance so that equasion does not work for me.
Sir, I would be very grateful if you answer this question: How is that a object accelerating at a speed of 9.8m/s but just covering 4.9m? And what does it mean by s/s(per second per second)? I am having a lot of trouble with this questions.So please kindly reply,Sir.
2 years late, but the reason is that it only reaches the speed 9.8 m/s at the 1 second mark. You can't travel 9.8 meters in the first second if your speed is less than 9.8 m/s for the entirety of that second. Remember, its speed is increasing from 0. So, as math would have it, the distance reached over the course of the first second is 1/2 that of the speed reached by the end of that second due to acceleration.
its a constant acceleration and not a constant velocity, the reason its constant acceleration is because distance to the reference object is decreasing, so the closer it gets the faster it goes, so it would be accounted for in this equation, that's my guess.
Very good explanations but it would be nice if you stated gravitational acceleration with the proper units. Instead of citing gravitational acceleration as -9.8, it would be better if you included the proper units of meters/s^2. So it should look like g = -9.8 meters/s^2.
None of this explains why the effects of bouyancy ceases to exist in freefall. Gas within a liquid will always go in the direction of acceleration. It doesn't, it freezes in freefall, telling us that there is no force involved in the downward vector.

My teacher honestly has an introduction video that says she doesn't explain things well so there are plenty of things on youtube. She just hands out homework and if you have a question she refers you the policies and procedures. I will no longer call her doctor but instructor.
You prevented me from dropping physics, thank you
I wish you were my teacher. you explain everything so well. I am actually understanding what you teach.
I still have problems analysing the equations and solving them, nothing that a bit of practise won't solve.
thank you for making this page.
You were my hero in statistics this summer, and now in physics this fall. Thank you, thank you, thank you

made me understand so much in less time. I love this man and I hope there can be more professors like him out there in the world!!!!!
Your videos are remarkable sir:))). Thank you, now I'm not having a hard time answering physics problems because of your impressive teachings. Thank you.
This guy is pure gold. I think he is the only one that should be allowed to use the verb "to explain" on YT Math/Physics channels
Wow! You are an excellent teacher, keep
Up the good work. Thanks for the lesson!
These are excellent videos. I wish most physics teachers were are clear and easy to understand when explaining how to solve these problems.
I learned Math from this guy. Thanks man, great job for the free Education
thank you you saved me so much research for understanding and formulas

Great teacher you are making physics so simple for me
Explanation was good. It was easy to understand! ☺
Thank you so much my great teacher
You are one a million . Thank you very much. Am very grateful.
ok..i concede..YOU are tbe Best Physics teacher Ive come across...ever. 59 year old YT student..studying physics FTHOI
Great tutorial!
omg this guy is an amazing teacher!
Thanks so much!

Very good teaching
Amazing teacher ❤❤❤❤❤
THANK YOU... SIR...!!!
Would you please do a projectile motion tutorial
what is the effect of mass of the ball in this problem.
I completely comprehend this. Thank you
Glad it was helpful!
2:03 I think it should be +9.8 because the object is not moving against gravity but if it went up it would be - 9.8
free falling bodie after some time its velocity constant tell me if a bike i ride is bike velocity constant please reply me
Thank you my tearcher
You are very welcome! Good luck in your studies!
When you throw an object directly down from a specific height rather than dropping it, will the initial velocity still be equal to 0?
When you throw something the initial velocity won’t be zero. It will be whatever speed the object had when it immediately left your hand.
How do you aply this to gravity with respect to starting distance to find the velocity at the ending destance. This equasion should not include time, just distance from object. I can not use the equasion “square root of 2gh” because that is implying that the stringth of gravity is constant and does not change with respect to distance so that equasion does not work for me.
Sir, I would be very grateful if you answer this question: How is that a object accelerating at a speed of 9.8m/s but just covering 4.9m?
And what does it mean by
s/s(per second per second)?
I am having a lot of trouble with this questions.So please kindly reply,Sir.
I think because the acceleration is -9.8m/s², so the distance covered in 1 second is just half of the acceleration
2 years late, but the reason is that it only reaches the speed 9.8 m/s at the 1 second mark. You can't travel 9.8 meters in the first second if your speed is less than 9.8 m/s for the entirety of that second. Remember, its speed is increasing from 0. So, as math would have it, the distance reached over the course of the first second is 1/2 that of the speed reached by the end of that second due to acceleration.
Wow nice teaching technique sir
Thanks and welcome!
how do you account for the increasing strength of gravity as the falling objects distance to the reference object decreases?
its a constant acceleration and not a constant velocity, the reason its constant acceleration is because distance to the reference object is decreasing, so the closer it gets the faster it goes, so it would be accounted for in this equation, that's my guess.
If he is my professor i will never skip classes :) .
think u very muchh

-9.8 m/s^2
Very easy
its perfect and i am nine years old
in 2020 and in after year
please belive me
30 minutes with you is more than 30 days in the classroom.
Tenchu bEri BerI matssss 😭☺️😀🙂😩😩😩😩🙂😀😀😭😭😭

what is saul goodman doing here and why is he explaining better than my teacher
Lol, it’s all good, man!
Why you not working at Spacex? I meant it.
