The questions in this quiz are suitable for GCSE physics students studying scalar quantities, vector quantities and calculations involving forces. If you struggled with the quiz, don't panic - we've ...

Notice how the quantities above have both a size and a direction associated with them. The direction of a vector can be given in a written description, or drawn as an arrow. The length of an arrow ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations ...

Figure 1: Schematic of the 3D force detection method on a Ge(001)-c(4 × 2) surface using bimodal AFM. Figure 2: Force component maps and force vector distributions above Ge(001) dimers. Figure 3: ...
