The first semester of an undergraduate physics course invariably spends ... First, it is technically a vector equation because the momentum of an object depends upon its direction of movement.

It’s a result that’s borne out by experiments in particle physics, which return results that are only consistent if the energy-mass-momentum equation holds true for photons. Setting E equal to mc^2 ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Save guides, add subjects and pick up where you left off with your BBC account. The questions in this quiz are suitable for GCSE physics students studying momentum calculations, conservation of ...

A+B together allows us to make the impact force internal (and not appear in the linear impulse-momentum equation). FBDs for A and B individually allows us to determine the t-direction components of ...
