How do inertia and gravity combine to keep Earth in orbit? Gravity keeps the moon in a constant free fall around the earth. The moon is far enough away that earth's gravitational pull will not cause a cataclysmic collision with the mo … on, but just close enough to keep it trapped in rotation.

Eclipses and the Moon's Orbit 4.1 Introduction. The Moon revolves around Earth in an elliptical orbit with a mean eccentricity of 0.0549. Thus, the Moon's center-to-center distance from Earth varies with mean values of 363,396 km at perigee to 405,504 km at apogee. The lunar orbital period with respect to the stars (sidereal month) is 27.32166 days (27d 07h 43m 12s).

The Forces Which Keep the Moon in Orbit Since the Moon revolves about the Earth in 27.322 days, V = 2пr / t, or. V = 2 x 3.142 x (3.844 x 10 m) / (27.322 days x 24 hrs/day x 60 mins/hr x 60 secs/min). giving, V = 1.023 x 10 m/s = 2,288 mph. Much faster and it could escape Earth-orbit; much slower and it would crash into the Earth.

How do gravity and inertia combine to keep the earth in its orbit? Answered by The Community. Making the world better, one answer at a time. The moon has inertia and wants to keep going in a straight line but the earth has a larger gravitational pull and wants to pull the moon towards it. This causes the moon to circle or orbit the earth.

Ask Us Because the Moon is in orbit around the Sun (as well as in orbit around the Earth). Another way of looking at it is that the center of gravity of the Earth-Moon system is revolving around the Sun, and the Earth and the Moon are revolving around their common center of gravity.

- The moon goes around the earth. The earth (with the moon going around it) goes around the sun. In cosmological terms, the earth and moon are close neighbours, and that's easy to spot by the fact that there were some magnificent moon landings by Nasa astronauts in the late 1960s and early 1970s.

Does the Moon Rotate? The orbit and the rotation aren't perfectly matched, however. The moon travels around the Earth in an elliptical orbit, a slightly stretched-out circle. When the moon is closest to Earth, its rotation is slower than its journey through space, allowing observers to see an additional 8 degrees on the eastern side.

Orbit of the Moon The Moon orbits Earth in the prograde direction and completes one revolution in approximately 27.322 days (a sidereal month). Earth and the Moon orbit about their barycentre (common center of mass), which lies about 4600 km from Earth's center (about three quarters of the radius of Earth).On average, the Moon is at a distance of about 385000 km from Earth's center, which corresponds to about 60 Earth radii.With a mean orbital velocity of 1.023 km/s, the Moon moves relative to the stars each hour by an amount roughly equal to its angular diameter, or by about 0.5°.n average, the Moon is at a distance of about 385000 km from Earth's center, which corresponds to about 60 Earth radii.

- THE SUN-EARTH L2 POINT. Earth is in a stable orbit around the Sun because our planet's forward motion exactly counterbalances the gravitational pull of the Sun at this distance (about 93 million miles).

The Moon's Orbit and Rotation Because of the effect on the Moon of tidal forces due to the Earth, the same side of the moon always faces the Earth. In other words, it takes the Moon the same amount of time to rotate around once as it does for the Moon to go around the Earth once. Therefore, Earth-bound observers can never see the 'far-side' of the Moon. Tidal forces cause many of the moons of our solar system to have this type of orbit.

Why does the moon affect earth's ocean tides? The moon has mass, therefore it has gravity. As the moon orbits the earth, its gravitational pull not only keeps the moon from departing its orbit due to centripetal force, it also pulls the coean water around with it. A spring tide is when the Moon, Earth, and Sun fall in a straight line.

Moons Jupiter's moons stay in orbit because gravity pulls them towards Jupiter. it mainly happens like a game of tug of war. Two forces are included, one pulls the moons towards Jupiter, the other one pulls them towards space.

- The force of gravity is decreased, but only slightly. The satellite is 4050 miles from the center of the earth, where we are roughly 3950 miles. The force of gravity is reduced by the square of the distance, but it is still strong enough to keep the moon in orbit some 230,000 miles away.

What are the two factors that keep the Earth in orbit around the Sun? Report Abuse. Gravity, inertia, and centrifugal force. Gravity keeps the Earth in orbit around the Sun Inertia is the force that keeps the Earth in motion. Centrifugual force is the outward force created by the Earth orbiting around the Sun. So there are actually three forces in play here.

Orbit of the Moon The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in approximately 27.323 days (a sidereal month). Earth and the Moon orbit about their barycentre (common center of mass), which lies about 4,600 km (2,900 mi) from Earth's center (about 34 of the radius of Earth).

Does the Moon Rotate? A changing orbit. The rotational period of the moon wasn't always equal to its orbit around the planet. Just like the gravity of the moon affects ocean tides on the Earth, gravity from Earth affects the moon. Gravity from Earth pulls on the closest tidal bulge, trying to keep it aligned.

What force keeps the earth in its orbit around the sun? Hitler used the THEORY of gravity to put fat people in concentration camps. The THEORY of microgravity might have its uses when you are on the Earth, but there is no scientific evidence for the THEORY of macrogravity that keeps the moon above the earth or makes the Earth go around the sun.
