Newtons law of gravitation
00:00 let's begin today's class so first my neutron's law of gravitation generator gravitational monarchy overnight uh what is gravitation okay so simple definitions of gravitational gravitation when you couldn't even do it about any two objects in the entire universe gymnastic force of attraction between any two bodies that can interact
01:11 with the moon also falls towards the earth the reality my moon is visiting away from the earth there's a lot of acting on that to know
02:14 some gravitational existence so to answer foreign so let's define the newton's law of gravitation statement layer or omega so newton's law of gravitation states that it states that the force of attraction
03:20 between two bodies is killed so the between two bodies is due to condition which ironically directly proportional to the product their masses that means force of attraction between two bodies given this f proportional to theta body commas m1 dot m2 the second inversely proportional to the square of their distance from their
04:25 center f proportion 1 by d square so you would say statement of newton's law of gravitational first statement like what's on that it states that the force of attraction between two bodies is directly proportional to the product of their masses m1 m2 now inversely proportional to the square of their distance only biscuit distance go uh inverse portions so from one end to q unit from one and two detail a combiner digital f is equals to g m one dot m two divided by d squared like injure using newton's law of
05:16 gravitational formula where g one is 10 to the power minus 11 our unit newton meter squared power kg square okay crash course you formulated seven into ten power minus eleven newton
06:49 meter square for kg square obviously all right questions related answer what is universal gravitational constant one right there is sodium what is universal gravitational constant what is its value uh organical so let's define universal gravitational constant so g lambda defined quantity formula but i defined f here f equals to g m one m two divided by d square i'm going to define one upon a g lights so g like a dragon right there so definition like a g equals to k water f into d square divided by m one dot
08:01 so if d equals to one meter m one equals to m two equals to one kg given the number g equals to f your conditionalizable that means what is g what is universal division constant that means universal gravitational constant g is defined as the g equals to k equals to f so g minus the average of here is the force of gravitation go for subscribers you know between two bodies so
10:45 force of attraction is directly proportional to the product of their masses inertia bisco product mask of product somewhat direct relationship and inversely proportional to the square of the distance from their center c understand zoom distance d this is statement number one statement number two statement combination f proportional to m one dot m two divided by d square answer yeah but you proportional sign you proportional sign autonomous is consequences of uh gravitational force that is consequences of
11:54 of gravitation otherwise the effects of gravitational force matter number one what are the consequences of gravitational force generally quality maxima of existence of solar systems on planets planets revolving around the sun at the moon around the earth uh due to the uh gravitational force organically second part you are able to walk i mean you see you need the building is standing on something do you want to go due to a gravitational force gravitational that's also due to gravitation these are
13:12 the effects and consequences of gravitation uh language i hope you understand that important questions so let's try to move fast or come on you go if you want to go deeply on this part oil maybe not refer to crash course example related examples so let's do that key equation also generally do maximum universal again x microsoft what happens uh what happens to the force of gravitation between two bodies we have two bodies obviously a direct condition also about the equation change in any taller changes okay
14:09 look like what happens between the force of gravitation between two bodies if the mass of one body is doubled if the distance between them is half of the distance between them is doubled masses triple distance is half is a reconditioner condition this what happens to the force of gravitation between two bodies if the distance between them is solution prime i go
16:50 g m one prime dot m two prime divided by d prime square condition the ao so g m one dot m two divided by u one by two square square negative one by four teleporting one by four d square it wasn't voila i mean i'll look at the law of induced islam you one by four tallahassee do you wanna understand equals to four times given g m one dot m two divided by d square square about if you have noticed clearly the ending of atomia equation one amino acid or know everyone numerically as an
18:43 example as a classmate so calculate calculate the force of gravitation between two bodies of mash two kg each separated by 2 meter distance okay your question there goes as an example money is six point six seven into ten compare
19:50 negative 11 newton of gravity is f equals to g m one dot m two divided by d square formulas are excellent beta positions given by super liquid affluent trigonometrical trigonometry so f equals to uh g one equals six point six seven into ten compare negative eleven into m one into m two into two divided by two square you sub answer it kirani two into two four teleported to two carbon four one second ratio which equals to six point six seven into ten four minus eleven you're in neutron sorry four seven and everything follow comment granola so
21:31 that we can like improve ourselves in the upcoming videos newton's law of gravitation could look back next video i mean gravity as a special case of gravitation the graviton related gaussian i think kind of like three four video chapters uh as you know miles from manchester united so i don't want to repeat that couldn't tell if you delete one so what do you think about today's video go down below put your comment like share subscribe and hit that bell going to stay home see you next video goodbye
