Are the Planets in the solar system held together by gravity from the sun?
Question:
Answer:
Not only by the sun;s gravity,coz otherwise they would rush into yhe sun.they have a certain centrifugal force of their own,which keps the 2 forces balanced,and their moton remains cinstant.the closer a planet,the higher sun;'s gravitational pull towards it,hence it has higher centrifugal force,that is,it rotates more quickly on its axis.
They are held in orbit 'round the Sun yes
yes
the planets orbit where the net force on them is balanced, gravitational pull of the sun being one of them
The planets are held together by their own gravitational fields. They are held in their orbits by the one from the sun.
They are held together by their own gravity.

Centripetal/ Centrifugal force... An experiment that will easily demonstrate the existence of both forces. Take a rope swing, and twist the rope until it knots. Sit on it and lay out flat. You will spin at a steadily gaining rate. Yet, if you twist your body so that you are turning into the spin, you will spin faster, a lot faster then the lose of air resistance can explain. Why?
When matter spins, it wants to throw matter from its core. Yet the angle of trajectory will not be perpendicular to the center of the mass, but at a forward angle with the spin. Since this energy is resisted by atomic bond, it becomes a stored energy. Yet perpendicular resistance of a force, creates a new energy. Perpendicular resistance of electricity allows this energy to cause friction, and or magnetic fields. Perpendicular resistance of centripetal force (the outward throw) allows the equal and opposite reaction of a stored centrifugal force (an invisible inward pull). Yet to tap into this force, all you have to do is have the stored energy of your muscles in line with it. Just like this, all of our planets tap into this force, and become in sync along the bigger forces equator.
If the planets weren't moving, they'd have no force to resist gravity, and would fall into the sun.
theory - solar system was formed from a swirling mass of gas
that as the mass swirled, clumps of gas were sent off on their own. But the gravity of the new sun held them from going totally on their own, and they went into orbit as centifigal force kept them from falling back into sun. Now as they cooled they became planets and moons and everything else, spinning around the sun being pulled into the sun by gravity but kept out with centrifigal force. Both science and theology agree on this, except science says billions of years, theology is 1 day. (where did the swirling masses come from to begin with?)
