The statement “force equals mass times acceleration” is newton’s second law of motion. why is this a law rather than a theory?

(a) it states, rather than explains, the relationship between the variables.
(b) it cannot be proven, whereas a theory can be proven.
(c) it may be revised if new information shows that the relationship has changed.
(d) it was classified as a law because it is related to other similar discoveries.

I think the correct answer from the list of choices is option A. The statement “force equals mass times acceleration” is Newton’s second law of motion. It is a law rather than a theory because it states, rather than explains, the relationship between the variables.

Answer;

(a) It states, rather than explains, the relationship between the variables.

Explanation;Newton's second law states that, the change of momentum of an object is directly proportionate to the applied or resultant force. This means that the momentum’s change will take place in direction of applied force.This is a scientific law, which states the relationship between, force, mass and acceleration; that is F= ma. The law clarifies why force is proportional to acceleration and also describes the observation that would be made if an object or a body is pushed at a constant force.Additionally, the law was formulated from observations and experimentation and not from assumptions and guesses, that is why it is a law and not a hypothesis or a claim.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
