Why is gravity able to accelerate an object with high static inertia (heavy object) at the same rate as an object with low static innertia (light object)?

e.g. A 100 ton ball will be accelerated at the same rate as a 1 pound ball. One would think that the 100 ton ball has much more static inertia than the 1 pound ball yet its acceleration and velocity is exactly the same as the 1 pound ball. How does gravity achieve this?

Inertia is the resistance to change in velocity, which we measure in kilograms.

Force is what is required to change the velocity of an object (accelerate) it. A force that accelerates one kilogram by one meter per second per second is one Newton. Newtons are how we measure force.

The weight of an object is the effect of gravity on the mass of that object, and the force of gravity is directly proportional to the mass of the object. On earth gravity exerts a force of 9.8 Newtons per kilogram.

If we know that acceleration=force/mass then we can solve for acceleration for any object with mass x knowing that the force applied by gravity is 9.8Nx(the mass of the object). Using x for the mass in kilograms that gives acceleration=(9.8Nxkg)/xkg. The xs cancel leaving us with acceleration=9.8m/s^2 for any mass (disregarding air resistance).

TL:DR Heavier objects have a greater force acting on them but it requires a greater force to accelerate them as well, so it all balances out.
