Answer on Mechanics | Relativity Question for WinKoOo

Question #25861
What is the relation between force and momentum?
Expert's answer
They are related by the fact that force is the rate at which momentum changes with respect to time:
F = dp/dt - Newton's 2nd Law
p - momentum;
F - force;
t - time;
m - mass;
v - speed;

If p = mv and m is a constant ( v<<c - speed of ligth ) , then F = dp/dt = m*dv/dt = ma
If F=constant:
F*Δt = ΔP
