they can be yes.
Such an object is said to be in free fall.
Yes, there is an object affected by only gravity. Stars and other floating space debris are only affected by gravity in space, as long as the objects do not touch each other.
Not only in space - gravity is universal. The force of gravity is affected by the distance, and by the masses involved.
Yes, Earth's gravity affects space by curving it, as described by Einstein's theory of general relativity. Gravity warps space-time, causing objects to move in curved paths around massive objects such as planets and stars. This effect is most noticeable in the orbits of planets around the sun.
Anything that isn't affected by the Sun's gravity will not revolve it. Almost anything outside of our solar system will not be affected by the Sun's gravity. But that's not to say that they aren't being affected by another star's gravity.
The force of gravity between an object and Earth keeps objects from floating into space. Gravity acts as a force of attraction that pulls objects towards Earth's center, preventing them from drifting off into space.
Objects float in space because there is no gravity to pull the objects down. While on earth there is gravity so it pulls the objects to the ground.
No, not everything floats in space. Objects with mass are still affected by gravitational forces, so they can be in motion or orbit around celestial bodies. In the absence of gravity, objects or particles with mass still have inertia and will continue to move unless acted upon by another force.
On Earth, gravity pulls objects like crumbs downward towards the ground. In space, there is microgravity, so there is no force pulling the crumbs in a specific direction. As a result, crumbs in space would tend to float around rather than fall to the ground.
yes
Yes. Gravity is the main force that affects the motion of objects in space.
Magnets work in space because they create a magnetic field that can attract or repel other magnetic objects. This is possible because the magnetic field is not affected by the lack of air or gravity in space.
