This is important, because getting into space, and maneuvering around while you’re up there, is all about changing your velocity. Effectively, the more delta-v you have, the farther your rocket can go.

This doesn’t mean you should just slap the biggest engine you can find onto your ship and assume you will go farther than if you used a smaller engine; bigger engines burn fuel at different rates, provide different amounts of thrust, and weigh more than smaller engines.
