... Why Energy Helps Motion, in general, is hard to calculate. Using forces, momentum, acceleration, etc. gets complicated because they are all vectors (have magnitude & direction). Energy is not a vector; it’s just a number. Can predict motion by figuring out how much energy that motion will “cost.” 2 ...
