In simple terms, this chapter explains how gravity really works from the perspective of Extended Classical Mechanics (ECM)—a new way of thinking about physics that treats motion, mass, and energy more physically than in traditional science.
First, it introduces a new idea: gravitational strength isn’t just about pulling objects downward—it’s about how much gravity reshapes the internal energy and mass of a system. ECM gives it a new name: gᴇᴄᴍ and it measures how much a system’s mass gets pushed around or deformed due to gravity.
Then, it explains kinetic energy (the energy something has when it moves) in a whole new way. Normally, we think kinetic energy is just something objects have when they move. But in ECM, kinetic energy is actually a temporary shift in real mass—some of the object’s matter is “borrowed” and turned into energy when it speeds up, and “given back” when it slows down or stops. This mass shift is shown as:
◉ (Original mass – shifted mass) + shifted mass = moving object with kinetic energy
◉ When slowing down: (Original mass + returned mass) – kinetic energy = rest
This leads to an even cooler insight about light and photons—particles that normally don’t have mass. ECM says they do have a kind of "negative mass" when they're moving. And when photons are near very strong gravity (like near a black hole), this negative mass becomes even more negative, making them more energetic. But they never turn into real mass—just more intense forms of energy in motion.
In short: gravity doesn’t just pull things—it reshapes the energy and mass inside things. Movement isn’t just about speed—it’s about a real, physical shift in matter. And light is deeply affected by strong gravity, changing its energy without ever needing a normal kind of mass.
This chapter lays the groundwork for rethinking gravity, motion, and energy from an entirely physical and measurable viewpoint—one that makes ECM a powerful tool for explaining nature in both ordinary and extreme situations.
