Computer Science gives you a strong theoretical foundation of "physics", so you understand the underlying concepts of "pulleys", not just how to use one or make one.
Computer Engineering teaches you how to make pulleys and how to pull on the ropes.
Software Engineering teaches you to integrate a pulley system into your catapult.
