The numerical value of acceleration due to gravity at the surface of the earth is 9.8 meter per square second or 9.8m/s. This is the value that is generally used.
If the mass is increased and gravity remains constant, the acceleration will decrease. This is because the force acting on the object remains the same due to gravity, but as the mass increases, the object will experience a greater resistance to acceleration.
Acceleration is measured in m/s2, not in m/s. Close to the Earth's surface, the acceleration due to gravity is approximately 9.8 m/s2. It varies a bit, depending on the exact location, but not enough to be noticeable except by careful measurement.
If gravity is the only force, they WILL have an acceleration of about 9.8 meter per second square, close to Earth's surface. However, there may be forces other than gravity involved - such as air resistance.
At the earth's center, the acceleration/force of gravity is theoretically zero.(At least the force of gravity between the earth and an object at its center. There's still the gravitational forcesbetween the object and everything else ... the sun, moon, stars, etc.)
To find weight when you know the mass, you can use the formula Weight = Mass x Acceleration due to gravity. Simply multiply the mass of the object by the acceleration due to gravity (usually taken as 9.81 m/s^2) to calculate the weight in newtons.
Sure. The acceleration of gravity at the 'surface' of Uranus is 8.995 m/s2 . . . about 92% of what it is on Earth, and greater than on Mercury, Venus, Mars, Pluto, or the moon.

The acceleration of gravity everywhere near the earth's surface is roughly 9.8 meters (32.2 feet) per second2.At different places, and on the ocean floor, and on mountains, it has slightly different values.

The air is close to the surface of the earth because gravity holds it there

The acceleration due to gravity on or close to the earth's surface is always g, (981cm/s/s). An object can be restricted from achieving this in many ways eg putting it on a table top. Nobody asks why the acceleration due to gravity is zero on table tops. Water also restricts acceleration due to viscosity, which, as for parachutes in air, will be velocity dependent. So the short answer is, in water the object is in a restricting environment, unlike in free fall where the acceleration will be g.
To find weight when you know the mass, you can use the formula Weight = Mass x Acceleration due to gravity. Simply multiply the mass of the object by the acceleration due to gravity (usually taken as 9.81 m/s^2) to calculate the weight in newtons.
9.81 m/s2 gravity is dependant on the total mass of the two bodies, and the distance between their mass centers, and irrespective of any motion or rotation on earth, their would be a very small acceleration due to rotation about the earths axis (0 at the poles , maximum at the equator) , but this is a totally seperate issue
Force = Mass x Acceleration F = ma W=mg It is the intensity of the gravitational field. The acceleration. due to gravity is the force experienced by a body of unit mass in a gravitational field. it is the force experienced by a body of unit mass towards the centre of the earth by the pull of the earth.
Gravity holds a planet's atmosphere close to its surface. The gravitational force of the planet's mass prevents the gases in the atmosphere from escaping into space. Without gravity, the atmosphere would disperse into space.
