onna ......

r= gravitational fields
r= radius(relative to the center of the earth)

na machan bala kapilayanawa nemeyi center ekethamayi Skanda kendraya thiyenne (center of the mass) eka nisa gravitational field ekak athiwenne na

like this

enna enna skandaya (mass eka) aduwenanisa thamayi prastharaye y=m.x akarayata (0,0) haraha yana widiyata aduwenne

gravity 1k nati wenawa bala rahitha nisa

ayiyoo nana "gravity 1k nati wenawa bala rahitha nisa"
nemeyi

wait mama kiyannam -:

gravity kiyanna guruthwakarshana shethrayaka thabu skandaya 1 Kg wana wasthuwak matha balayane

eee balaya Newton's Universal Gravity Equation eken F = GMm/R²

hoyaganna puluwan M and m kiyanne mass G kiyanne sarwathra guruthwakarshana niyathaya R= araya so 1 Kg k skandayak gaththahama eka matha balaya=0 wenna puluwan M (when m=1 Kg) =o unahama witharayi neda??

R

o if R=o and M

0 F ---lim---> infinity

so... ehema wenne nana but black holes kiyanne ehema ewata as we know black hole walata light ekath adala gannawa that's why they call black holes( kalu kuhara)

**********************************************************************************

Anika -: me prasthare earth eke araya(radius) eken passe gravity field eka aduwenne rekiiiyawa nemeyi ehema wenne G,m,and M also niyathayan wena nisa then F samanupatha wenne 1/R² ta witharayi ehema prasthaara walata kiyanne rigukoonasra bahuwalayak kiyala boyil niyamaye prastharaye(PV=K) wage

M.C.Q​

1. How can an apple pull the Earth toward it?

* Apples are very strong and good for your health

* All matter exerts the force of gravity on other matter

* An apple cannot pull the Earth toward it, since it is so small

2. Why does an object weight less on the Moon?

* It has less mass on the Moon

* There is no atmosphere on the Moon

* The force of gravity is less on the Moon

3. Why don't the planets fall into the Sun?

* They have enough speed to keep them in orbit

* They do, but we just don't notice it

* The force of gravity pushes the planets away from the Sun
