What is angular momentum?
1) Calculate the tidal force (the difference in gravitational force from right to left side or G(R) - G(L) ) from a person sitting next to you (approximately 1 meter away). You will need to make some estimations on mass and size of a normal person.
2) Compare the tidal force on a person from the Moon and a person standing nearby (the answers to the previous two questions). Which is greater and by how much?
What is the angular momentum of the Moon in its orbitaround Earth?How does this angular momentum compare with theangular momentum of the Moon on its axis? Remember that the Moon keeps one side toward Earth at all times.Discuss whether the values found in both parts seem consistent with the fact that tidal effects with Earth have caused the Moon to rotate with one side always facing Earth.

- How do planets orbiting the Sun and skaters doing a spin both conserve angular momentum?arrow_forwardUsing data from the previous problem, find the increase in rotational kinetic energy, given the core’s mass is 1.3 times that of our Sun. Where does this increase in kinetic energy come from?arrow_forwardThe Sun’s mass is 2.01030kg , its radius is 7.0105km , and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5103km , what would its period be if no mass were ejected and a sphere of uniform density can model the Sun both before and after?arrow_forward
- Why is it that the moon exerts a larger tidal force on the Earth than the Sun does, even though the Sun is so very much more massive than the Moon?arrow_forwardWhile the Earth spins around its axis and orbits around the sun, then suppose we remove the sun from its location, will Earth continue to spin around its axis and orbits around the point where the sun used to be? Why or why not?arrow_forwardIf you were on an alien planet, where multiple sources of gravity were affecting you, would the stronger gravity take precedence or would they cancel one another out? And why?arrow_forward
- If earth starts revolving with more speed then normal , what happens??arrow_forward48. In Cosmic calculate 9.1 we found tidal force that earth exerts on the moon. Following the SAME PROCEDURE, calculate the tidal force earth would have exerted on the moon shortly after the moon formed, when it was only about 1/10 its current distance from earth. How much greater was the tidal force than it is today? What does this tell you about how a factor-of-10 change in distance affects the tidal force? (9.1--->.
