Equations of motion - Wikipedia
https://en.wikipedia.org/wiki/Equations_of_motionThe first general equation of motion developed was Newton's second law of motion. In its most general form it states the rate of change of momentum p = p(t) = mv(t) of an object equals the force F = F(x(t), v(t), t) acting on it, The force in the equation is not the force the object exerts. Replacing momentum by mass times velocity, the law is also written more famously as
