00:00In the 7th crystal, the Indian mathematician Brahmagupta talks about an attraction ball

00:15which attracts all the things in the world towards the earth.

00:19This attraction is called the attraction towards the earth or the earth.

00:25According to the Newtonian principle,

00:28for any ball, an attraction is created in the object.

00:32If this attraction is applied to a small m-sized object with the help of F,

00:38according to Newton's principle, F is equal to small m into a.

00:43Now, if this ball or the object or the earth is experiencing a great attraction,

00:50then F is equal to small m into aX.

00:59If the object or the earth is experiencing the same kind of attraction,

01:04then F is equal to capital M aE.

01:14From these two equations, we get small m aX is equal to capital M aE

01:21or small m by capital M is equal to aE by aX.

01:27Since the object is smaller than the earth,

01:32the earth is smaller than the object.

01:36For this reason, the attraction of an object towards the earth or the earth is called the attraction towards the object.

01:43We do not apply the attraction towards the earth.

01:45Because its value is irrelevant.

01:47It can also be called the combination of the inventive equation.

01:50Due to the influence of the attraction ball,

01:52the object or the object, which can move with time,

01:57is called the inventive equation.

02:00Its value is 9.8 meters per second.

02:05Now, let's go back to the Newton's ball and its relation.

02:08We know that F is equal to small m into aX.

02:13From here, we can find that aX is equal to F by M.

02:19Due to the influence of the attraction, the object or the object is called the small g.

02:24That is, small g is equal to F by M.

02:29Now, from the inventive equation, we get F is equal to g into M by R square.

02:37That is, the inventive equation will be small g is equal to M by R square.

02:45From this equation, it can be understood that the inventive equation of an object is not dependent on its value.

02:53The value of the earth is dependent on the distance between the object and the center of the earth.

02:59In the inventive equation, this equation is valid for the object or the object around it.

03:06But if the object is much higher or lower than the object,

03:10does it mean that it will remain the same?

03:12No, it will not remain.

03:14Why it will not remain or what will happen when it changes,

03:17we will know in our next video.

03:20Keep watching.
