Question 3 • Biology

The statement “force equals mass times acceleration open paren cap f is equal to ma close paren ” is Newton’s second law of motion. Why is this a law rather than a theory?

Answer
A
It states, rather than explains, the relationship between the variables.
B
It may be revised if new information shows that the relationship has changed.
C
It was classified as a law because it is related to other similar discoveries.
D
It cannot be proven, whereas a theory can be proven.

Explanation

A scientific law describes a consistent relationship or pattern in nature, while a theory explains why that pattern occurs. Newton’s second law states that force equals mass times acceleration (F = ma); it gives the relationship between those variables without explaining its cause. So the best choice is “It states, rather than explains, the relationship between the variables.”
