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, ...

Interstellar object 3I/ATLAS is showing signs of "non-gravitational acceleration" as it reached its perihelion.

\(\Delta v\) (pronounced 'delta v' is the change in speed of the object. Acceleration is measured in metres per second per second or metres per second squared \(m\, s^{-2}\). How to measure ...
