Thanks for your effort in this video. I need to understand clearly the difference between acceleration due to gravity and gravitational field strength as a concept , Numerically it is the same but I believe there is a big difference between them

Why gravitation field strength is given by the formula G*M/r2? why not GM/r? or GM/(2r). I have seen a definition of field strength = F/Q, but why is that? why not F/(2Q)? or F/Q2?, is this word "strength" related to stress-strength as in mechanics?

Firstly thanks for the awesome video, helped me understand a lot. I just have one question, when calculating the field strength for the baseball, I arrived at an answer of 2.4 x 10 ^-9, while your answer is 2.4 x 10^-12. I used the exact values shown in the video and arrived at a similar answer, just a few orders of magnitude difference. Not sure what I have done incorrectly…

Correct me if I am wrong but didnt einstein find out what makes gravity(due to distortions in space-time).Why wouldnt it be a force?Asking because a lot of people say the whole gravitational theory is wrong

Hard/tricky question: Is the gravitational force greater on one of 2 objects of the same mass and the same distance from a planet if one of the objects has a much larger area? For example, if there are 2 objects made of solid gold, one is a perfect sphere 1 meter in diameter and one is the flattest possible pancake 1 atom thick millions of meters in diameter, will the flat piece of gold accelerate faster? In other words, since the volume of the 'cone' from the center of the planet to the circle of the objects is greater for one of the objects, is there greater gravitational force on the object with the 'cone' with a much greater volume? Is this question overlooked because everyone assumes all objects are spheres and area is never calculated? What if all the gravitational force were focused like a laser 1 foot in diameter, would the force be the same several light years away causing objects to accelerate at the same speed no matter how far away they might start out at?

I tried to calculate the gravitational field strength of the moon if its radius was 9.3 inches and I got 3.24078e-17parsecs/s so I think I did something wrong.

@Bozeman Science the gravitational field (strength) or just gfs when I looked in multiple websites, the formula had 2 nearly identical equations: 1 was in the video g=GM/r^2, while another uses g= – GM/r^2. I'm confused as to which one I'm going to follow, especially when deriving the formula.

This is cool, thanks!

Thank you so much for helping me with everything!

thank you sir

thnks alot i hope u have more views and subs soon

but what if i want to know the gravitional intensity outside earth surface like that of moon ??

at 2:57 the mass of the baseball does not need to be known and doesn't matter

only the mass of the planet (Earth) matters

i thought u need the mass of both objects?

Super explanation

i thought he was a biologist!

Thanks for your effort in this video. I need to understand clearly the difference between acceleration due to gravity and gravitational field strength as a concept , Numerically it is the same but I believe there is a big difference between them

Can anyone give me proper definition for Line of filed of gravitational and electric field?

Does anyone know how I can calculate this into Cartesian form?

Why gravitation field strength is given by the formula G*M/r2? why not GM/r? or GM/(2r). I have seen a definition of field strength = F/Q, but why is that? why not F/(2Q)? or F/Q2?, is this word "strength" related to stress-strength as in mechanics?

nice

Love!

can any tell me the broder of gravitational field of Earth

i love dis video

Thanks sir!!!! I really understood that video

There is no force in gravity: See Relativity. Its all curved space time, no forces. Unless you think that's nonsense, which it is!

Very helpful !!👍

THank you for the explanation

nut

goood

did Einstein failed the gravitational law through his space time curvature theory?if so then why do we still study gravitational law

So for an object in air, eg a plane that is x meters away from the ground, r would be: x plus the radius of the earth??

good

“Find the magnitude of earths gravitational field at the moon” is the question but my class just learned part of this topic and I’m so confused.

Yes. That was indeed quite helpful

Hi…Field strength tells you the force that works on opposite object…but gravity is an acceleration on a small body by a bigger mass…

i have not learned anything

Hi. Can you explain what a “Field” is please? Thx. D
