The difficulty to accelerate an object is related to its mass, not to its weight. However, on Earth (i.e., more or less constant gravity), mass and weight are also proportional.
As to "why", I believe that is still an area of active research. We know that there is a property called mass, that causes gravitation, and inertia (i.e., a resistance to acceleration), but the exact nature of this property is still being studied.
No, it is not harder to accelerate a moving object. The initial motion of the object does not affect the force required to accelerate it further. The force required to accelerate an object depends on its mass and the desired acceleration.
It is harder to stop a heavy object because it has more inertia, which means it resists changes in its state of motion. More force is required to stop a heavy object compared to a lighter one due to its mass.
It certainly does. That's why you have to push it harder to accelerate it horizontally. But that "more weight" that it has is exactly the more force it needs for vertical acceleration, and that's why all objects fall with the same acceleration.
A heavier object has more mass than the lighter object.The acceleration of any object is (force on the object) divided by (the object's mass).A = F/MAs this simple fraction shows, if equal forces were applied to many different objects, you'd immediately see that the smaller an object's mass is, the moreacceleration results.
The mass of an object is directly proportional to its inertia. Inertia is the resistance of an object to changes in its state of motion, and a greater mass means more inertia - meaning it will be harder to accelerate or decelerate the object.

An object is lighter on the moon because the moon is smaller and thus lighter than the Earth

Because lighter stuff float but Heaver stuff don't

Whichever is lighter will accelerate more quickly.
Heavier than air objects accelerate downwards. Lighter than air objects accelerate upwards until they are no lighter than the air around them.
The mass of an object is directly proportional to its inertia. Inertia is the resistance of an object to changes in its state of motion, and a greater mass means more inertia - meaning it will be harder to accelerate or decelerate the object.
