Only one force is required: gravity ... the gravitational attraction between the
center of the earth and the center of the sun. If gravity were not at work, then
the Earth would take off in a straight line, into deep space. And if another force
were required, we'd be out of luck, since the gravitational attraction is the only
force that exists.
Gravity, and inertia. The inertia of any moving mass tends to keep it moving at a constant velocity, in a STRAIGHT LINE.
But if the Earth were moving in a straight line, it would move away from the Sun. The gravity of the Sun tries to pull the Earth down, and INTO the Sun. The delicate balance of inertial and gravity keep the Earth (and all the other planets) in stable orbits.
The Earth is kept in orbit around the Sun by the gravitational force between the
Earth and Sun. The Moon is kept in orbit around the Earth by the gravitational
force between the Moon and Earth.
In each case, the gravitational force is all that's needed, which is lucky, because
the gravitational force is all there is.
Inertia ("A body in motion will tend to remain in motion") keeps the Earth moving in a straight line out away from the Sun. Gravity, the attractive force between all mass in the universe, pulls the Earth directly toward the Sun.
Balanced together, the Earth is moving forward as it falls into the Sun. But the Earth is moving so fast - about 67,000 miles per hour in its orbit - that it keeps MISSING the Sun!
gravity pulls them together and motion in a circle keeps them apart , stable orbits are a precise balance of the two
Its mass and its velocity. All governing functions of Earth's position rely on these two factors.
The Sun's gravity and the Earth's velocity (at a tangent to its orbit, at any instant) around the Sun.
Gravity and momentum. Gravity causes the moon to continually "fall" toward Earth, and momentum causes it to always miss, because the momentum stays perpendicular to the force of gravity.
Gravity is the only thing required to keep objects in orbit,
which is pretty lucky, because that's all there is.
The two factors are gravity and inertia.

the rotation of the earth around the sun
Earth's equatorial circumference is about 24,900 miles. Twenty thousand trips around the earth would rack up half a billion miles.
I am not sure what you mean by "swimming". The movement of one object around a point outside it - in this case, the Earth around the Sun - is called "revolution". The movement of an object around an axis within the object is called "rotation". Earth does both. It revolves around the Sun with a period of one year, and it rotates around its own axis with a period of one day. Answer2: The earth revolves around the sun like a cork in a Ocean current. The current carries the earth around the sun. The Circulation Force is DelxcP where P is the earth's Momentum and c is the speed of light.

three hundred and sixty five and a quarter (365 1/4) days. The four 1/4's make up the extra day on the leap year.
The Earth rotates on its axis, as it simultaneously revolves around the sun.
The Earth has an imaginary shield around it.
No The moon roates around the earth. The earth rotates around the sun within the solar system.
No. The moon revolves around Earth, and Earth revolves around the sun.
The sun doesn't travel around the earth. The earth travels around the sun.
The Earth rotates around it's axis.The Earth revolves around the Sun.
the moon travels around the earth,and the earth travels around the sun
No, Mars does not orbit around the Earth. The moon orbits around around the Earth. Both Earth and Mars orbit around the sun, but Mars is farther away from the sun.
The earth obits around the sun.
