ELI5: How does gravity exactly work and why do objects increase in speed when falling from different heights?

I get the apple theory loosely but I want more understanding.

It's important to *really drill in people's heads* that gravity has two parts, the law and the theory.

The law bit is really simple: Objects with mass attract each other. How much they attract each other depends on their relative masses. Attraction means accelerating another object towards you. Here, the Earth accelerates every object towards itself at a constant rate of 9.82 meters per second per second. If we ignore things like air resistance, every object accelerates at the same rate when falling.

The theory part refers to how gravity actually works: is it a field? is it a particle? that's the part we haven't yet figured out.
