It isn't so much the weight that matters as it is the density. Gravity accelerates all (only small things; if the object's gravity can move the earth, then the calculations change dramatically) things equally, but air resistance causes "fluffy" objects to fall more slowly than dense objects. For example, of you drop a rock and a feather, which one falls faster?

We all know that the rock falls faster; but when the Apollo astronauts did this experiment on the airless Moon, the rock and the feather fell together at the same speed. On Earth, the air slows the movement of the feather much more than the movement of the rock.

With no air resistance, it wouldn't matter if you threw a dense object or a light one, but on Earth in our atmosphere, a dense object will go farther than a light one. Find a wiffle ball and a small pebble that have the same weight; throw them together. The pebble will go farther even though the wiffle ball is the same weight.

But if you will shoot the object, it becomes more complicated. It will take more energy to accelerate the more massive one (due to its inertia). So you will find that there is a ideal weight: a light mass will accelerate quickly, but then slow due to the air; while a very massive object will not move at all!

A massive object will not start as fast, but due to the same inertia, it will not slow down because of the air.

This would be a fun experiment to compare work done on an object, surface area, and distance.

Technically, if there are no specified resistive forces, any force applied will cause the object to accelerate and not slow down until another force is applied to it. But if there are resistive forces, the same force will generally accelerate a light object faster than a heavier one.

If they were fired from the same catapult in a vacuum, the lighter object would go further.

This bit isn't strictly accurate.

(In the air, the lighter object is more likely to be affected by wind and air resistance and travel a smaller distance.)

Larger objects are affected more by increased air resistance.

They distance travelled by both objects is directly related to the force applied by the catapult.

If for example a piece of stone weighing 1 ton was fired it would travel a given distance let's say 1 metre for arguments sake. To throw a ton a metre away takes a lot of energy.

If we were to apply that much energy to 1000 pieces of stone say a kilo in weight each, we're still throwing a ton and they will travel about the same distance.

However if we use that same force on a single piece of stone of a kilo in weight, its going to travel much further.

The change in motion or acceleration of an object depends on its mass and the forces acting upon it.
If an equal force acts on two objects of different mass then the more massive object will accelerate at a lower rate than the less massive object. If no other forces act on the objects then both will continue indefinitely.
