Question

(see the imagine attached)
I give medals c:

Answer 1

OK i guess at point C , as force due to gravity is F =Gmm/r^2
where r is the distance between sun and comet
i.e F is inveresely propotional to the r
also F = ma
i.e Acceleration a is directly propotional to the r
that means
Acceleration is inversely proptional to the r as well
so lesser be the distance between the sun and comet, more be the acceleration , so at point C it will have max Acceleration

Answer 2

So, if C has max acceleration what force causes the Moon to orbit the Earth? @CyberShadow

Answer 3

the gravitational force of attraction between moon and earth causes the moon to orbit the earth

Answer 4

but what does it have to do with acceleration at Point C? :P

Answer 5

Is the sun a satellite of the earth? @CyberShadow

Answer 6

lol No! , Sun is a Star,.a satellite is a thing that orbits around a planet, but sun dont orbit around earth , earth orbits around Sun :P, Moon on the other hand is the satellite of the earth

Answer 7

so would the earth or the sun revolve around it's axis? @CyberShadow

Answer 8

earth and sun both revolves around their own axes

Answer 9

would that make the revolution and rotation of Earth identical? @CyberShadow

Answer 10

ohh u meant revolve , sorry, i misunderstood, Earth revolves around the sun, Sun and Earth both rotates about their own axes

Answer 11

do you know what is the amount of time it takes an object to complete a revolution called? @CyberShadow

Answer 12

Time period of revolution

Answer 13

What do Kepler's laws describe?
does it have something to do with the orbits? @CyberShadow

Answer 14

yes they have something to do with orbits, Kepler got three laws :P

Answer 15

U can google them

Answer 16

is this ur homework or what? cos we have moved way out of initial question lol xD

Answer 17

I'm trying to study for finals, haha @CyberShadow

Answer 18

haha,well Good luck! then
