gravitational force (1 Viewer)

[clever angel]

hi again

use available EVIDENCE to discuss the factors affecting the strength of the gravtitaionl force

i know wat the factors are but wat about the evidence?

plzzz help

 

[rama_v]

Umm I think here they just mean that the different experimental values of g that are attained in different altitudes and locations, but i might be wrong

 

[香港!]

would the equation F=Gm1m2\r² be regarded as "evidence"???
from that equation the factors are worked out.

um i think u could say that at the poles the distance to the center of mass of the earth...center of gravity is less than that of the equator.

therefore by this 'EVIDENCE' the strength of the gravational force varies with distance

another point could be a comparison between the effects of walking on earth and the moon since the earth>moon in mass...

if the planet has a radius larger than earth's but same mass as Earth then it has a lower gravitional force
if a planet has higher mass then it has larger gravitional force
factors such as latitude and altitiude affect the gravitional force as well
