Sun's gravitational pull keeps the earth in an elliptical orbit around it.
If there would be no gravitational pull of sun on earth than the earth would start moving in a straight line at an angle of 90 degree like a tangent to a circle.
Inertia is what keeps a moving object moving. That is, if an object is moving, it has the tendency to continue moving.
What keeps the planets in orbit, in a way, is gravity - with only inertia, the planet would move in a straight line, but gravity provides the force to make the planet change direction.
inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
Interia and Gravity are the force that attracts all objects toward each other.
Yes. Clearly the Earth orbits around the Earth.
Gravity and Inertia
The gravity pulls them together
Nitrogen levels and surface radiation.
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
Yes; the sun's gravity keeps the Earth orbiting around it.
Yes. Clearly the Earth orbits around the Earth.
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
no the earth does
Gravity and Inertia
Gravity and Inertia keep Earth in orbit
The inertia of earth combines with gravity to keep it from colliding with the sun
The gravity pulls them together
The mutual forces of gravity between the Earth and sun maintain the Earth's closed orbit. So that's "Gravity" for number-1, that's all there is, and that's all it takes. There is no number-2.
You're half-way there. The mutual, equal gravitational forces between the Earth and Sun maintain the Earth's stable, closed, elliptical orbit around the Earth/Sun common center of mass.

The force of gravity that they exert on each other, and the velocities of the Moon and Earth which is their "inertia".
