Gravity- it’s known as the “weakest fundamental force”, but we know the “attraction” is really just objects falling along the curvature of space toward a more massive object. I don’t understand how this explanation of gravity relates to the other fundamental forces.

A lot of good answers, so I will try to summarize.
Classical (Newtonian) Physics: gravity is a force because it accelerate mass.
General Relativity: gravity is not a force. This theory very successful at explaining orbits, light bending around suns and galaxies time dilation observed on satellites around Earth.
Standard Model of Particle Physics: these guys are obsessed with particles and they want a particle for anything. Because of this, they are stubborn at insisting that gravity must be a force and we just need to find a particle (graviton) that carries that force. They also insist that it must be this way also because General Relativity doesn’t reconcile with Quantum Physics.
