Why is gravity still described as a “force” when Einstein described it as the curvature of spacetime?

Question

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.

Answer 1

The Equivalence principal says that a uniform gravitational field is indistinguishable from a uniform acceleration. Newton defines a force as that which accelerates a mass. Gravity causes acceleration and is thus is a force.
