For the purposes of the argument, I am assuming that the earth already has a velocity (Speed and Direction). Any mass in space (i.e. a low gravity environment), would travel in a straight line until it comes into proximity of another object of sufficient mass.
Basically, the earth would travel in a straight line until it came across another star, at which point it would change direction.
If you want to think in bigger contexts, you could say that the earth will travel in a massive orbit around the galaxy since the galaxy's core is of sufficient mass to affect the direction of travel of earth.
Gravity is everywhere in the universe. There's no getting away from it, anywhere.
If th sun's gravity were to disappear, Earth would go off in a straight line into interstellar space.
Yes. Gravity is what keeps them in orbit. If it were not for gravity, those astronauts would continue out into space in a straight line.
As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force required for circular motion.
If there was no gravity, objects would not be pulled towards the center of the earth, so they would not go straight. Instead, they would continue in whatever direction they were moving until acted upon by another force.
Force of Gravity is why the earth circles.
Yes. It is gravity that keeps those objects in orbit. Without gravity they would simply move in a straight line.
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.
the gravity moves the Earth in a circle
no, there is always gravity
Without the suns pull of gravity, the Earth and any other planet would move in a straight line. It is the sun that forces the planets to move in an orbit.
NO
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.
Gravity is everywhere in the universe. There's no getting away from it, anywhere.
Yes, Earth would still have gravity without the sun. Gravity is a fundamental force that exists between all objects with mass, so Earth's gravity is due to its own mass, not just the presence of the sun. The sun's gravity does impact Earth's orbit and tides, but Earth would still have its own gravitational field even without the sun.
The earth does move due to gravity.Without gravity, the earth would move in a straight line. The force of gravity between earth and the sunis what bends the earth's path into a closed curve around the sun, called earth's "orbit".
If th sun's gravity were to disappear, Earth would go off in a straight line into interstellar space.
