inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
What else can I help you with?
What makes the plants orbit?
A planet's inertia and its interaction with the Sun's gravity make it orbit around the Sun.
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 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.
What force counteracts a planet's inertia and keeps the planet in its orbit?
Gravity is the force that counteracts a planet's inertia and keeps it in its orbit. The gravitational force between the planet and the star it orbits causes the planet to continuously fall towards the star while simultaneously moving tangentially at a sufficient speed to remain in a stable orbit.
What would happen to an object in orbit around a planet if the planet's force of gravity were stronger than the object's inertia?
The object would crash into the planet.
What two factors act together to keep the planets in orbit around the sun?
definetly Gravity and Inertia
What would happen to an object in orbit around a planet if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
How do moons orbit the planets?
the planets do not orbit the moon but the moon orbits the planets because of gravity and inertia
What force is responsible for the orbit of the planet in the solar system?
That would be gravity and inertia.
Inertia makes a plant tend to travel in a straight line but what keeps it in orbit?
Gravity keeps a planet in orbit. Inertia tries to make the planet move in a straight line. The balance between the two makes the planet orbit a sun.
How do gravity and inertia determine the orbit of a planet?
the sun's gravity pulls the planets towards it but the other planet's gravity helps keep the planet not get sucked towards the sun. With gravity working this creates the planet to orbit the sun
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.
