Inertia is defined by Newton's first law,
"Objects in motion stay in motion, objects at rest stay at rest"
If a planet had no inertia it could come to a stop or accelerate to high speeds without any force applied to it. It also would not find an orbit.
Inertia is a fundamental property of the law of conservation of energy.
Without it, the planet, and the universe would be quite, quite different.
What else can I help you with?
If gravity or inertia stop working what would happen to the earth?
If gravity or inertia were to suddenly stop working, the Earth would no longer be held in its orbit around the Sun and would go off into space in a straight line. It would no longer have the centripetal force needed to keep it in its circular orbit. The lack of gravity would also cause everything on Earth to float away into space.
What would happen to a human if they traveld to planet mercury?
they would problobly die or get frozed
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.
What effects the revolution time of each planet?
The size of the planet and the inertia it begins with. Inertia is the resistance to changing velocity (either speed or direction). All objects in the universe are already moving, so the planet, while moving, was caught in gravity of another object (like the Sun) and trapped in revolution. The amount of inertia, determined by mass, normally, influences how fast an object revolves.
What would happen to a planets orbit if its inertia increases?
Essentially nothing. When the central body is greatly more massive than the objectin orbit around it, (think a planet around a star, or an astronaut space-walking outsidethe Shuttle), the orbiting body's mass has no effect on the size or period of its 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 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.
What would happen to an object in orbit around planets if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
What would happen if a planet had no interia?
If a planet had no intertia, it would stop orbiting its star, it would stop spinning on its axis, and it would simply sit there, unmoving relative to its solor system, except when it was hit by a moving object that did have inertia. Even the smallest particle with inertia would cause our planet to be pushed ahead of it until our planet rolled off of the particle to one side or the other. Since your question did not indicate an absence of gravity, too, then objects on the planet including its atmosphere would remain there. If there was life on the planet, all the life forms dependent on day/night cyles would wither and die.
What force is responsible for the orbit of the planet in the solar system?
That would be gravity and inertia.
What tries to make planet move in a straight line?
Its inertia.
If the moon did not have inertia as it travled around the earthwhat would happen?
If the moon suddenly decided to stop pusing forward (inertia), the balance between inertia and the earths gravity would cease and the moon would come crashing into us. :)
Does a planet have the greatest inertia?
It depends on what type of planet it is.... which one is it?
What would happen if there was no inertia?
Without inertia, objects would not resist changes in their motion. This means that any force applied to an object would instantly change its speed or direction, making it impossible to move or control objects effectively. The concept of momentum would not exist, leading to chaotic and unpredictable movements of objects.
When did Fatal Inertia happen?
Fatal Inertia happened in 2007.
What would happen if you hit a planet?
Nothing No One Can Hit A Planet
How do planets stay in their orbits yet not get sucked in to the Sun?
Gravity and inertia both contribute to their orbits. Inertia tends to move a planet away from the Sun, while the Sun's gravity tries to pull the planet closer. Without one of them, a planet would either float away from the Sun (inertia only) or burn up from the Sun (gravity only).
