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, ...

\(\Delta v\) (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 ...

I love using seemingly random data to figure out stuff I wouldn't otherwise know. You can do this with all kinds of things, but in this example, I use video that I recorded from an airplane to figure ...
