Final answer:
A scientific principle is a useful general rule or law based on accumulated data. For example, Newton's second law, F = ma, is a scientific principle relating force, mass, and acceleration.
Step-by-step explanation:
A scientific principle is defined as a useful general rule or law based on the accumulation of data. It is a statement that explains a wide range of observations and is supported by evidence. For example, Newton's second law, F = ma, is a scientific principle that relates force, mass, and acceleration.
