Newton's law of gravitation:
F=GMm/r^2
F must be a vector for anything beyond trivial systems.

Newton's 2nd law:
F=ma   ;  also a vector equation
3rd law:
for every action, there is an equal and opposite reaction

For collisions, you must use the conservation of momentum (different depending
on the case), and solve for the wanted variable.
p1=p2
p1=initial system momentum, p2=final system momentum
p=mv, but unless you are doing something very simple, p must be treated as a
vector.

What do you mean by "transference of energy?"

An excellent book on interstellar travel (both conceptual, and mathematical
treatments of all types of propulsion are given) is
"The Starflight Handbook" by Gregory Matloff and Eugene Mallove, 1989.
