they arent falling at the same speed because gravity is stronger with a heavier object
No.....because we need both mass and velocity to find the momentum if velocity is same that is 9.8m/s that is of free falling bodies.........mass will effect the final result.
They'll both reach the top of their arcs, turn around, and begin to fall at the same time, fall with the same acceleration, and hit the ground at the same time with the same speed.
Objects of different masses accelerate at the same rate on the moon because the acceleration due to gravity on the moon is constant for all objects, regardless of their mass. This is because the force of gravity is proportional to the mass of the object, so the acceleration is the same for all objects.
... different. Kinetic energy is proportional to the square of the speed, wherease momentum is proportional to the speed.
Gravity affects all objects equally regardless of their mass, causing them to accelerate towards the ground at the same rate. This is described by the principle of equivalence, as stated in the theory of general relativity. Thus, objects of different masses will fall at the same rate when dropped from the same height in a vacuum.
In vacuum, all masses big and small fall with the same acceleration, and reach the same speed in the same amount of time.

Galileo's experiment to show that mass had little effect on the speed of falling objects involved two cannonballs of different sizes being dropped from a certain height. This showed that, in a vacuum at least, falling objects fall at the same speed no matter their mass.

Yes, different isotopes of the same element have different masses.
The astronaut, space ship and everything in it are all falling at the same speed (falling around the Earth is called ORBIT). If everything is falling at the same speed, they are effectively weightless. Its like falling in an elevator, if everything is falling at the same speed you will appear to be floating around the elevator. Until it reaches the basement.

Because here on Earth, in the 'laboratory' where you must make all of your observations, everything you see falling must fall through air. The presence of air has a substantial effect on what you observe. If you could do the experiments without air, and have nothing but gravity affect your falling objects, you would see a feather and a truck fall with the same acceleration, reach the bottom at the same time, and hit the ground with the same speed.
If the weight of both masses are the same.
Their masses are different. (Mass = density * volume)
