The speed of light, denoted by the symbol "c," is a fundamental constant in physics and has a value of approximately 299,792,458 meters per second (m/s).
On the other hand, mass is a property of matter and is typically denoted by the symbol "m." It is measured in units such as kilograms (kg).
Dividing the speed of light by mass (c/m) does not yield a physically meaningful quantity. The reason is that the speed of light is a fundamental constant that is independent of mass. It is not directly related to the mass of an object or any specific physical property associated with mass.
However, in special relativity, there is an equation that relates energy (E), mass (m), and the speed of light (c) known as Einstein's mass-energy equivalence equation: E = mc^2. This equation shows that energy (E) is directly proportional to mass (m) and the square of the speed of light (c^2). It indicates that a small amount of mass can be converted into a large amount of energy.
So while the speed of light divided by mass (c/m) does not have a direct physical interpretation, the relationship between energy and mass, as described by Einstein's equation, is an important concept in physics.
