Engineering vs Computer Science

[sohcahtoa]

I will be starting college in the fall, but I'm not sure which path I'd like to take. I struggled with physics during high school but enjoyed the class, but being at a high school level, I don't think I'm cut out for engineering. I was considering Mechanical Engineering, Industrial Engineering, or Computer Science. I have some background programming, I enjoy math (not fantastic at it though), and I want to work in the automotive, robotics, or renewable energy fields. Any advice?

Edit: I guess it should also be noted that I placed into College Algebra (2 steps below Calc [requires a 29] at my University) with my ACT score, meaning I'll be slightly behind.

These are more electrical engineering fields. I am not sure how much computer science you would find in them.

This does not matter if your willing to do the work.
