Why planets and moons of planets stay in their orbits?
The forces of gravity between two masses are the cause of all orbits.
What two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
What force is operating between Sun and planets is it centripetal or centrifugal force?
The forces of attraction between the sun and each planet are gravitational forces, and they're both centripetal forces.
What is a force that only acts between planets?
There is no such force. All forces that act on planets work on smaller particles as well.
Newton learned that the orbits of planets are the result of what two forces?
Gravity and inertia.
Venus is located between what two planets?
Venus is located between the planets Mercury and Earth.
What affect does the sun have on one of your planets?
the affect is 90 between two planets
What is the relationship between a planets distance from the sun and distance between planets?
If two planets are in orbits with radii of R1 and R2, the distance between them varies from R2-R1 to R2+R1.
What two planets is earth in between?
Mars and Venus
Which two planets is earth in between?
Venus and Mars
Is Mars between other planets?
Mars is the 4th planet around the sun and it revolves between two planets Earth and Jupiter.
Why are forces balanced or unbalanced on planets?
The forces on the planets are not balanced. The gravitational force between the sun and each planet is what keeps the planet in orbit around the sun. If the forces on a planet were balanced, then the planet would sail off in a straight line, and would never be seen or heard from again.
