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.
What are the two factors that keep the earth orbiting the sun and the moon orbiting the earth?
Gravity and Inertia. The gravity keeps the planet, moon etc. going in a circle and inertia keeps it going (inertia is the tendency of a moving object to continue in a straight line or a stationary object to remain in place. If there was no gravity the planet, moon etc. would just go in a straight line but with gravity it pulls it in a circle like a string attached to an object at the center.
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.
How are all the planets kept in orbit by gravity?
The sun's gravity exerts a constant force on each planet in the direction straight toward the sun, but the law of inertia tries to keep the planet moving in a straight line. The resultant force from the vector addition of those two forces keeps the planet in its orbit.
How inertia and gravity combine to keep earth in orbit?
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
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.
What is the property of matter that keeps it moving in a straight line or keeps it at rest?
Inertia

gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
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.
Which force is responsible for making planets and satellites travel in near circular orbits?
Gravity is the force responsible for making planets and satellites travel in near circular orbits around a central body, such as the Sun or a planet. The gravitational pull between the central body and the orbiting object keeps it in a stable, elliptical path.
If a car runs out of gas on a flat straight road the car keeps rolling is that inertia or force?
That is inertia. Inertia is the tendency of an object to remain in its state of motion (either at rest or moving in a straight line) unless acted upon by an external force.
Which force keeps the space station in orbit?
The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.
Does inertia move up?
yes, inertia moves up. it is a good thing and a bad thng. inertia keeps earth and other planets in its orbit, as long as it has gravity which moves in a straight line.
What two factors combine to keep the planets in their orbits?
None do. If the forces on a planet were balanced, then it would take off in a straight line at constant speed, not remain in orbit. The only force acting on a planet is the gravitational one, that attracts the planet toward the sun. Fortunately, that's the only force required to keep the planet in orbit.
