The term "constant" refers to something that doesn't change. In mathematics, science, and engineering, a constant is a value that remains the same no matter what.
For example, in an equation like \( y = 2x + 5 \), the number 5 is a constant because it always stays the same, regardless of the value of \( x \). Similarly, in physics, constants like the speed of light (\( c \)) or gravitational constant (\( G \)) are considered "fundamental" constants because they have fixed, unchanging values.
So, itβs called a "constant" simply because it represents a value that doesn't varyβit stays "constant" throughout any calculation or process.
