Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

It is not quite accurate to say you can measure acceleration. It is more accurate to say we measure things like time and distance and then use these measurements in order to calculate the acceleration ...

So, where is the anomaly? According to Loeb, the mystery is why we haven't spotted many more interstellar objects before we ...
