## AP-C: Regarding the nature of the EM force (photons)

I did some reading to try to address the question from class regarding the nature of the EM force and the exchange of photons between charge carriers, creating a change in momentum (a.k.a an impulse) on those objects. This discussion seems very relevant, but may require some additional reading.  The main idea is pretty easy …

## AP Physics C: Momentum #2.6

A block of mass m1 = 2.0 kg slides along a frictionless table with a speed of 10 m/s. Directly in front of it, and moving in the same direction, is a block of mass m2 = 4.2 kg moving at 2.8 m/s. A massless spring with spring constant k = 1100 N/m is attached …
