A Harvard astronomer has proposed a bold theory about a mysterious interstellar object that has been observed accelerating ...

Astronomers have attempted to explain the non-gravitational acceleration of comet 3I/ATLAS, our third confirmed interstellar ...

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, ...

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used. Watch this ...

The Manhattan-size interstellar object 3I/ATLAS exhibited signs of non-gravitational acceleration and appeared “bluer than the sun” as it passed our local star — which could be signs of an alien craft ...

Calculus is the study of change. More specifically, it is a method for understanding rates of change. If you know an object’s velocity and want to calculate its acceleration, then you need calculus ...

Even in some of the most extreme areas in the universe, Albert Einstein’s theory of general relativity seems to hold up. A test of a key tenet of general relativity using three stars has shown that ...
