to simply put, multiplication was used in the given (6.67)(2.25) = 15.0075 move the decimal point to the left (once) and you get 1.5 usually answers are expressed like these examples: • 1.0 • 2.5 • 7.8 and use exponents to shorten big numbers therefore, 1.5x10^-10N i suggest you look up scientific notation so you can get a better understanding :))

That possible?

So what your saying is you do from your "feet" not from the center of your personal mass or did you mean that when you said from where you where standing?

how dowe calculate the mass of one of the objects if the distance of null point,distance between two objects and mass of one of the object is given.

Great class congratulations

Thanks for making gravitation easier

Dude thank you so much!

thank sir it was really helpful

how you calculate the kg formula in void ?

2:34 did you mean Time or Distance. I think you mean Distance because in relation to earth a human simply doesn't have the mass to stay in orbit unless moving at a unfathomable speed.. at least in my opinion of course

I have got one question. How is force inversely proportion to the square of distance.

But how do you take into account the volume of these objects? So far you are compressing the mass in a particle and not in an inmense volume (which might not act as depicted by the formula)

How you find the magnitude of gravitational force between two objects.given the masses and the distance between them?

I have a question? Based on the examples from the books about statics, why gravitational force is not included between two objects there? Only the weight or the gravitational forces between object and Earth are only included and not G.F. between two objects. By that case, where could Gravitational forces between two objects be applied?

Do you give exactly calander date and time for next earthquake by using G and g

very helpful

Thank you so much 😊

Actually in the perfect round revolution gravity is taken out, the newton intuition and explanation is half right half wrong. The force of gravity cancels out in the formula. In an elliptical revolution the condition of falling and missing fits better, but again just in the falling pathway. Isn't it?

Really you are intelligent, Thanks a lot sir ❤

ty so much, my physics teacher is horrible at teaching and should not be doing so, unlike you, your amazing! Thanks for the help!

It is helpful .i love it. But always ask that what force if radius is zero or what will happen to core of the earth b/c radius is zero. What do you think ?

@carultch

2 жыл бұрын

The formula might lead you to believe that the gravitational force would be infinite, but nothing could be further from the truth. This formula is only strictly true for point masses. You can prove with Calculus that it applies for spherically symmetric masses of any size and distance as long as they are external to each other, with that last phrase being the key point. It only applies when the bodies are external to each other. If you consider something in the center of Earth, you'd have to add up the gravity due to every piece of Earth as vectors, because Earth is not a point mass. Given a spherically symmetric world, at the exact center of it, the gravitational force adds up to zero. So you would be weightless in the center of Earth.

Nice thank you very much!

What about 3 objects?

From my 12 year old : gravitational force is the force that attracts me to Earth and is also the force that attracts the Earth to me. So if we have a population explosion will the Earth expand?

I have a question using this formula and using my weight of 68KG and the suns mass 1.989e30 kg and being 150,7070E6 km from the sum I get a force of 397372.6 newtons toward the sun, and since we are going aroung the sun at tremendous speed the outward force must be equal or else we would be torn apart, am I correct? Just a thought. .. Corrections and critizems welcome...

It would be awesome if that last problem can be worked out with out a calculator! Studying for the MCAT and didnt get 126N lol

Chelsey Criswell multiply 2.25 with 6.67 which is approximately 15.0 but to put the number into scientific notation you need to move the decimal 1 over making the scientific notation number 1.5 x 10 to the-10 istead of the -11

Thank you🤗

How to compute the force between you and the moon?

why we take the centre between this two objects???

I have only seen the Newton described as kg*m/s^2. How do we get (m/kg)^2?

Is that 78kg the mass of somebody on the surface???

Sierra Ok, so i know its pretty late to answer for now, but just in case I wanted to help since this has been stumping me as well. So remember the formula wheras F1=F2= G M1 x M2/ distance or radius ^ 2, you have to square the radius or distance and then divide it by the numerator's product. It seems really insignifcant but it makes all the difference. Hope you or anyone else can find help from this :3

Will we get the same answer by using w= mg

If all objects have a gravitational pull, if we add more objects/mass to the equation dose it still work. For example the mass of you + the earth+ the tree next to me + my house would it still work and make sense

The origin of momentum creation is founded on the application of energy. Momentum serves as the initial cause of pushing and pulling. The energy, emanating from the internal core of a planet, is what gives rise to momentum, commonly referred to as gravity, and not due to the planet’s size, mass, or space-time curvature. For example, when energy is applied, it generates the necessary momentum for the actions of pushing and pulling. Without the application of energy, momentum cannot be established. Consequently, force cannot be exerted for pushing and pulling, as it lacks a physical existence. This, in turn, clarifies why force is not gravity. ~Guadalupe Guerra

So what is it a Force or an Acceleration ?

what if not all objects fall to earth at 9.8m/s, but close since the objects' gravity is too minuscule to alter the speed.

At 5:28, why do we take the distance from the center of the moon to the earth's surface? Should it not be the distance to the earth's center? Thanks, and sorry in advance if I missed something.

Because he wants to measure the gravitational force between him and the moon, and since he was standing on the moon it was to the moons surface. If he was calculating the gravitational force between him and the earth then he would have it be the center of the earth. I'm sorry if I'm not explaining this very well, I've never been very good at explaining things but I hope that helps!

how did he get 1.5?

If you were to make a spherical hole at the centre of the Earth and put yourself dead centre, with the distance between two masses being zero does that mean the gravitational force is infinite? Very helpful vid, thanks!

AuroraDarkStar That is an interesting question. However, you cannot say that something divided by zero is infinite (I thought that too, and had a long discussion with my maths teacher about it). Maybe you can calculate it using the limit of the formula as v approaches 0?

so would gravity be an element?. what if you dont want to kno force of gravity?. what would gravity be?

5:28 I am getting the answer as 126.30N...Is it correct or wrong???

Haven’t found it yet, but back in the day I used to know it, the gravitational formula on the face of the earth. There is no such thing as a true ‘center of gravity’ outside a singularity. On the face of the earth, one is pulled mostly straight down, but also at angles. Was hoping this video pointed that out.

Thank you

so did the calculation for the moon, but with my own weight. Then i used newtons second law to determine the acceleration due to gravity which came to 1.62 m/s squared. then i did the same with earth, but i got 11.15 m/s squared. Which was of course wrong because its 9.807 m/s so i was wondering if i may have done something wrong.

Wow wonderful 😍😍😍 thanks alot...Aparin

Makes so much sense! But then what happens when a rocket is traveling perpendicularly away from the earth toward the moon, not accelerating but moving at a constant speed? Is there a small gravity toward the bottom or engines of the rocket since this is in the direction of the earth? At some distance weightlessness should balance between the pull of the moon and earth. I imagine there’s a name for this equilibrium point in space

Thanks sir

Thanx a lot

Great explanation but, that “Four” kinda got me😂

isn't newtons a measurement of weight, not gravitational pull? did you mean that the objects that were 3 Kg would weigh 1.5*10^-10 newtons under each others gravitational force? other than that small miscommunication this is a good explanation on the math.
