Also question is, is engineering the same as physics?
Physics is a scientific discipline. It involves the study of atoms, and it's movements through earth environment. Engineering is a practical discipline which takes the scientific knowledge and develops new thing or new ways of doing things i.e. processes!
Furthermore, is engineering harder than physics? Depends on who you ask. Engineering students likely find physics harder (I certainly do), physics students may find engineering harder. Everything is harder when it's something you're not interested in. And that is all the physics options such as General, space, nuclear, and computational.
Keeping this in view, are engineers good at physics?
The short answer is: yes, you can still be a good engineer even if you don't "understand physics". The degree to which an engineer uses physics varies depending upon the type of engineering and career. If you end up in a research position, you will have to be able to work in the physical world and that means physics.
