Here we explore why objects fall at the same rate in a gravity field. You will first learn that the acceleration due to gravity is the same for an object of any mass. Next, we explore the modern theories of physics to explain why an object experiencing a larger gravitational force should accelerate at the same rate as an object with less mass. We review Einstein's thought that inertial mass equals gravitational mass for any object. We further explore that in Einstein's Theory of General Relativity, objects simply follow straight paths through a curved space time continuum. The falling objects we see as the force of gravity is just a geometric effect of all objects trying to follow a straight path in a curved space.
