\(\Delta v\) (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 ...

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 doesn't seem like such a difficult question, but it always brings up great discussions. If you drop a heavy object and a low mass object from the same height at the same time, which will hit the ...
