-- The purpose of the launch vehicle is to give the spacecraft velocity,
not force.
-- The launch vehicle gives the payload the speed it needs, in the direction
it needs, to take it to wherever you want it to go.
If it's a 'space'-craft, and perhaps you want it to stay in this neighborhood
for a while before sending it out on its long journey, you might launch it into
Earth orbit first.
The question is very broad. If the payload is a TV satellite, then it would
be placed first into low Earth orbit, and only later raised to its operational,
geosynchronous orbit. If the payload is a nuclear warhead, or a primitive,
deadly firecracker launched for resistance and fun from Gaza, then it would
be aimed to strike its ultimate destination by surprise and as soon as possible.
