The acceleration affects the weight of the person and object
The surface gravity of Neptune is 1.14 times the gravity on Earth. This means that the effect is almost the same as here on Earth.
An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
At the surface, it's about the same as the Earth's . You get a bit of variation in the value given, but, at the equator, it's about 1.065 times the Earth's. It is about 0.92 times the Earth's gravity, if you take into account the effect of the planet's rotation.
Gravity behaves exactly the same on Mercury as it does everywhere else in the universe. Taking into consideration the mass and radius of Mercury, you would calculate that the the acceleration due to gravity at its surface, and therefore the weight of any object on its surface, are about 38% of what they are on Earth, and you'd be correct. That's what they are.
The gravity present on a planet is usually denoted by the acceleration an object would experience due to gravity on that planet's surface. If we stick to Newtonian gravity (which should be adequate for our present purpose) the acceleration due to gravity on a planet is given by: a = G*M / R^2 Where G is Newton's gravitational constant, M is the mass of the planet, and R is its radius (remember we are standing on the surface). (Note: Here I have neglected the vector qualities of acceleration, this will not matter at present, the acceleration will be pointing down, towards the center of the planet.) From this formula we can see that the acceleration increases if the mass of the planet increases. This is to be expected; gravity (in Newtonian gravity) is caused by mass, and thus a bigger mass means a stronger gravitational field. Since Venus is less massive than Earth we might expect the surface gravity on Venus to be less than on Earth. However, we also have the R^2 in the denominator. This means the surface gravity on a planet will increase if the radius decreases (and the mass stays the same). This is also clear; if the radius is less then you stand deeper into the gravitational field. Venus is about the same size as Earth so this effect should not play as much a role as the difference in mass does. Thus, just by using these arguments we can already conclude that the surface gravity on Earth is larger than the surface gravity on Venus. Let us now look at some numbers. Earth's surface gravity is about 9.81 m/s^2 (it varies slightly from location to location). And Venus' surface gravity is 8.87 m/s^2, which is less, as expected. This means that if you weigh 70 kg on Earth you will weigh 70*(8.87/9.81) = ~63 kg on Venus.

Speed or acceleration have no effect on gravity.
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
Gravity provides a force; any net force will result in an acceleration, i.e., a change of motion.
On earth, the mass of an object has no effect whatsoever on its acceleration due to the force of gravity. All objects fall with the same acceleration, regardless of their mass. Any observed difference is due entirely to air resistance.
Gravity has an effect on all objects, including objects of different shapes and sizes.
No effect. All masses experience the same acceleration due to gravity.
Acceleration simply refers to the rate of change of a velocity. You might say that the effect of an acceleration - any acceleration - is therefore a change of velocity.
usually gravity is called the force of earth with witch it pulls objects towards it.when an object moves away from the surface of earth then this force affect on that object and tried to pull towards the earth.
It isn't clear what you mean by "objects of unequal forces". Gravity exerts a force on objects.
As soon as you go below the surface, it will decrease (dont ask for the calculations) until at its centre where acceleration due to gravity will be 0.
Gravity causes forces that attract every two objects in the universe toward each other.
