Hey everyone. I'm kind of new to the whole physics world, but I've got a question I've been wondering about.
So the Sun attracts the Earth because of gravity (or bends space time that the Earth is traveling through), and my question is this: Since photons have momentum, and momentum must be...
Given the mass of the sun, the gravitational constant, the period of Earth's orbit, and the semi-major axis of Earth's orbit, is it possible to find the eccentricity of the orbit? If yes, how?
Hi there, I've got a theoretical question i was hoping to gauge opinion about:
Is there any feasible situation which could change the Earth's orbit (without obliterating all life in the process)? And if so what would you imagine the effects to be, say for example if the Earth were to move...
Hi,
If we were to change the Earth's orbit, what force should we apply and in what direction? Shoud we go against G.(M_Earth + M_Sun) / distance^2 or against the centripetal force, M_Earth.v^2/distance?
I've calculated this last one and I got the result:
3,542396634E+22 Newtons
Is...
Yes i understand that i posted this earlier, but it was perhaps just glanced over since it had got replies (by me trying to bump it up, sorry, again). But i seriously would like to know how to solve this question ANy help would be appreciated
Note that i have copiedd the question exactly from...
i need help on this.
how much greater is the angular momentum of the Earth orbiting about the sun than the moon orbiting about the earth? (using a ratio of angular momenta)
angular momentum = rotational inertia x rotational velocity
radius of Earth (equatorial) 6.37x10^6
radius of...
kinetic energy...
The Earth's distance from the sun varies from 1.474e8 km to 1.525e8 km during the year. Take the Sun to be at rest.
Determine the difference in the Earth's kinetic energy.
Would I just use K=.5mv^2? If so what would v be?
If not, how would I set this up?
Thank you.
