Why do planet stay in their orbit?
The "inertia" of the moving planet combines with the force of gravity between the planet and the Sun, causing the planet to move in an orbit around the Sun. "Inertia" is basically the tendency for a moving body to move in a straight line unless acted upon by a force (such as gravity).
What is the link between the suns gravity and the motion of a planet?
The Sun's gravity causes a planet to move in its orbit. The Sun's gravity provides a centripetal force. The effects of the Sun's gravity, combined with the planet's inertia (tendency to move in a straight line), results in a planet's elliptical orbit.
What forces act to hold a planet in orbit around the sun?
The gravitational force between the planet and the sun is what holds the planet in orbit around the sun. This force keeps the planet moving in a curved path around the sun, in balance with the planet's inertia.
Why is planet earths journey around the sun?
The reason that Earth travels around the sun is because of gravity. The Gravity of the sun pulls all the planets towards it. This gravity will pull all material that is not moving into it, and material that is currently moving will be pulled into an orbit. The shape of the orbit depends on the original speed of the object.
What keeps a moon in orbit around a planet?
gravity :)
Why do the moons stay in orbit around Jupiter?
The moons stay in orbit around Jupiter due to the planet's strong gravitational pull. This gravitational force keeps the moons in check and prevents them from moving away into space. They orbit around Jupiter because of the balance between their inertia and the gravitational force pulling them towards the planet.
How do gravity and inertia keep the planet in orbit around the sun?
inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
What force keeps a planet in its orbit around the sun?
gravity
What force keeps a planet in its orbit around the sea?
Gravity
How do the planets orbit around the planet?
Planets orbit the sun in a counter clockwise motion, due to the balance between the Sun's gravity and the gravity of each individual planet.
What two factors keep a planet in orbit around the sun?
Two factors that keep a planet in orbit around the sun are the planet's velocity and the gravitational pull of the sun. The planet's velocity creates a forward motion that prevents it from falling into the sun, while the sun's gravitational pull keeps the planet moving in a curved path, which forms its orbit.
What keeps a satellite in orbit around a planet?
It is not gravity because there is no gravity in space, only some on certain planets, deffiantly on earth. It is done by the strength from other planets the sun for instance. Heat waves. Some of the gravity in space does help keep the planets and satellites in orbit.
