Mass variation refers to the change in an object's mass due to its energy content. Simply put, it tells us that the mass of an object can fluctuate depending on how much energy it possesses. This means that the mass of an object can change when it's interacted with or when it's moving at high speeds.
It's important to note that mass variation is not the same as mass itself. Mass is a fundamental property of an object that remains constant regardless of its energy content. It's the total amount of matter within an object, and it's unaffected by its energy state.
Imagine a toy car that's moving on the ground. Its mass is constant, regardless of how much energy it has. However, when the car is placed on a trampoline, its mass changes because it has more potential energy. This means that the car's mass is different when it's on the trampoline compared to when it's on the ground.
This concept is quite counterintuitive, but it's a fundamental aspect of understanding how objects behave in special and general relativity. It helps us to understand how the mass of an object can change depending on its energy content, which ultimately affects its behavior and interactions with its surroundings
