will the gravity decrease with increasing heights?
there is even a formula for it !
may i know the formula for that?
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.
m1 & m2 are mass of any 2 bodies. r is distance between them. G is gravitational constant.
wikpedia explains it nicely http://en.wikipedia.org/wiki/Gravity_of_Earth
\[\color{green}{G=6.67\times10^-11 units.}\]
& 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.
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.
\[\color{blue}{\text{Force should be this: -}}\]\[\LARGE{\color{RED}{\overrightarrow F.}}\]
\[\color{green}{\text{Should=Must*.}}\]
i would not say that gravity decreases with more altitude but yes it would decrease with distance from the mass.
