What is a constant in science?

A constant in science is a fixed value that does not change. Constants are used in scientific equations and formulas to make calculations more accurate and consistent.

One example of a constant in science is the speed of light, denoted by the symbol c. The speed of light in a vacuum is approximately 299,792 kilometers per second and is considered to be a universal constant.

Another example of a constant is the gravitational constant, denoted by the symbol G. This constant is used in equations to calculate the force of gravity between two objects.

Constants are an important aspect of scientific research and understanding, as they provide a consistent reference point for measurements and calculations. By using constants, scientists can ensure that their results are reproducible and accurate.
