## srev98 Group Title will the gravity decrease with increasing heights? 2 years ago 2 years ago

1. AravindG

yep definitely !!!

2. AravindG

there is even a formula for it !

3. srev98

may i know the formula for that?

4. maheshmeghwal9

yep u must have right to ask that$\LARGE{\color{red}{F=\frac{Gm1m2}{R^2}}}$ If u increase the distance{R}, force will definitely decrease & so the gravity would also decrease.

5. maheshmeghwal9

m1 & m2 are mass of any 2 bodies. r is distance between them. G is gravitational constant.

6. srev98

thanx friend

7. AravindG

wikpedia explains it nicely http://en.wikipedia.org/wiki/Gravity_of_Earth

8. AravindG

look under altitude

9. AravindG

thats the formula

10. maheshmeghwal9

$\color{green}{G=6.67\times10^-11 units.}$

11. maheshmeghwal9

& good one according to @AravindG . $\huge{\color{Purple}{g_h=g_0\left(\frac{r_e}{r_e+h}\right)^2.}}$Where; 1.) "gh" is the gravitational acceleration at height "h", above sea level. 2.) "re" is the Earth's mean radius. 3.) "g0" is the standard gravitational acceleration.

12. maheshmeghwal9

This one is also used for proving ur question:)$\LARGE{\color{red}{F=\frac{GM_1M_2}{R^2}.}}$Where; 1.) M1 & M2 are masses of 2 bodies. 2.) G is Gravitational constant. 3.) R is distance between those two bodies. 4.) & F is the force felt by them.

13. maheshmeghwal9

$\color{blue}{\text{Force should be this: -}}$$\LARGE{\color{RED}{\overrightarrow F.}}$

14. maheshmeghwal9

$\color{green}{\text{Should=Must*.}}$

i would not say that gravity decreases with more altitude but yes it would decrease with distance from the mass.

16. morales89

yes

17. marcw12345

yes
