... How can a force act at a distance? If I took my electron away from the proton and brought a positron (positive e) near the proton, the positron would . . . • accelerate away from the proton So, does my proton exert a force if no one is around to feel it? • Force, no. But we can define an electric f ...

... The conservation of linear momentum requires the total change in momentum of the collision, ΔpF + ΔpM, to be zero. The addition of Equations (2.40) and (2.44) clearly does not give zero. Linear momentum is not conserved if we use the conventions for momentum from classical physics even if we use ...
