Model Answer: The Moon would move in a straight line, except the Earth's gravity exerts a centripetal force (toward the center of the Earth) on the Moon. Because this force is in balance with the linear path of the Moon, the net result is near circular orbit around the Earth. Explanation: This is a top score answer. The answer explains that the gravitational pull from the Earth keeps the Moon in orbit. It also explains why this orbit is circular, explaining that the net forces are nearly equal.

What is the source of the centripetal force that keeps Earth in orbit around the Sun?
The centripetal force that keeps Earth in orbit around the Sun is caused by the gravitational attraction between Earth and the Sun. This force pulls Earth towards the Sun and prevents it from moving in a straight line, instead forcing it to travel in a curved path around the Sun.
What keeps moon from shooting out into space?
The Moon is kept in orbit around the Earth due to a balance between its inertia (which tends to make it move in a straight line) and the gravitational pull of the Earth (which keeps it in a curved orbit). This gravitational force constantly pulls the Moon towards the Earth, keeping it in its orbit.
Why do the satellite not fall while revolving around the earth?
They do fall. But they're traveling fast enough so that the surface of the Earth falls away from them as fast as they are falling. Same thing that keeps the Earth from falling into the sun.
Why does moon stay in orbit around earth?
The moon stays in orbit around Earth due to the gravitational force between the two bodies. This force keeps the moon moving in a curved path around Earth, preventing it from flying off into space. The balance between the moon's forward motion and Earth's gravitational pull maintains its stable orbit.
How does a rocket lift off the ground and what keeps a satellite in orbit?
A rocket can rise into the air because the gases it expels with a downward action force exert an equal but opposite reaction force on the rocket. Satellites in orbit around Earth continuously fall toward Earth, but because Earth is curved they travel around it.
Inertia is the force that keeps earth traveling around the sun?
Yes, but the Gravitational pull is also at play.
How does gravity influence the Earth's orbit around the sun?
Gravity is the force that keeps the Earth in orbit around the sun. The sun's gravity pulls the Earth towards it, causing the Earth to move in a curved path around the sun. This gravitational force is what keeps the Earth in its stable orbit and prevents it from flying off into space.
What is the source of the centripetal force that keeps Earth in orbit around the Sun?
The centripetal force that keeps Earth in orbit around the Sun is caused by the gravitational attraction between Earth and the Sun. This force pulls Earth towards the Sun and prevents it from moving in a straight line, instead forcing it to travel in a curved path around the Sun.
What makes the Earth orbit the Sun?
The Earth orbits the Sun due to the gravitational pull between the two objects. This gravitational force keeps the Earth moving in a curved path around the Sun, following its orbit.
Is the pull of gravity between the moon and the earth keeps the moon orbiting the earth?
Yes, the gravitational pull between the Earth and the Moon is what keeps the Moon in orbit around the Earth. This gravitational force is what causes the Moon to travel in a curved path around the Earth rather than moving off into space.
What to factors act together to keep earth in orbit around the sun?
The mutual gravitational attraction between the earth and the sun is the force that keeps the earth in orbit around the sun. It's the only force required, which is lucky, because it's the only force that exists.
How does the moon stay in orbit around the Earth?
The moon stays in orbit around the Earth due to the gravitational pull between the two bodies. This gravitational force keeps the moon moving in a curved path around the Earth, balancing the pull of gravity with the moon's inertia to maintain its orbit.
What keeps moon from shooting out into space?
The Moon is kept in orbit around the Earth due to a balance between its inertia (which tends to make it move in a straight line) and the gravitational pull of the Earth (which keeps it in a curved orbit). This gravitational force constantly pulls the Moon towards the Earth, keeping it in its orbit.
Why do the satellite not fall while revolving around the earth?
They do fall. But they're traveling fast enough so that the surface of the Earth falls away from them as fast as they are falling. Same thing that keeps the Earth from falling into the sun.
The Earth orbits around the sun because the gravitational force that the sun exerts on the Earth?
Yes, the Earth orbits around the sun due to the gravitational force exerted by the sun. This force keeps the Earth moving in a curved path around the sun, preventing it from simply moving in a straight line out into space.
What keeps it in orbit around earth?
earth's gravity
Why does moon stay in orbit around earth?
The moon stays in orbit around Earth due to the gravitational force between the two bodies. This force keeps the moon moving in a curved path around Earth, preventing it from flying off into space. The balance between the moon's forward motion and Earth's gravitational pull maintains its stable orbit.
