Yes, there is still gravity in a vacuum. Gravity is a fundamental force that exists everywhere in the universe, including in a vacuum where there is no air or matter.
Yes. Gravity attracts every speck of mass in the universe to every other one, even though in almost all cases, there's nothing but vacuum between them.
In a vacuum, where there is no air or matter, gravity still exists and continues to exert a force on objects. The absence of air resistance may result in faster acceleration of objects in a vacuum compared to in the presence of air.
Vacuum itself does not have gravity. In a vacuum, there is an absence of matter and gas particles, so there is no medium for gravity to act upon. Objects in a vacuum are subject to the gravitational pull of nearby massive bodies like planets or stars.
A pendulum can oscillate in a vacuum even in the absence of gravity because the motion of a pendulum is governed by its own momentum and inertia, rather than by external forces such as gravity or air resistance. As long as the initial push sets the pendulum in motion, it will continue oscillating back and forth due to its own energy, even in a vacuum.
An object's weight in air is the same as its weight in a vacuum. This is because weight measures the force of gravity acting on an object, and gravity affects objects in air and in vacuum in the same way.

This ratio is called the specific gravity.
No - gravity acts across the vacuum of space - this is how the moon affects our tides.
Gravity waves travel as small distortions in space and time.
Whether or not you float has nothing to do with vacuum. You float because you are too far away from the earth (or other massive objects) for their gravity to have any noticeable effect on you. It just so happens that this occurs in space where natural vacuum may be found.
An object's weight in air is the same as its weight in a vacuum. This is because weight measures the force of gravity acting on an object, and gravity affects objects in air and in vacuum in the same way.
Yes, gravity does work in a vacuum. Gravity is a fundamental force of nature that acts over a distance, so it can still exert its pull between objects even in the absence of air or other matter. This is why objects in orbit around Earth, such as satellites, experience the effects of gravity despite being in a vacuum.
No, a feather falling in a vacuum is not considered projectile motion. Projectile motion involves an object being launched horizontally with a certain velocity while experiencing the force of gravity, causing it to follow a curved path. In a vacuum, there is no air resistance or drag force acting on the falling feather, so it falls straight down due to gravity.
