We can't tell you what you will or will not be good at. You're still very early in your education if you want to be an engineer, and there's no real way to know where your strengths and weaknesses lie.
The first thing I would do is figure out why you are doing poorly in your physics class. Do you understand the concepts but get stuck on the math? If so, then look into why you're getting stuck on the math. Quite often students will think they understand the concepts and just don't get the math, but it's actually the other way around. The math is often just simple algebra and arithmetic. But understanding what all you need to include when trying to solve a problem becomes difficult if you do not understand the concepts well enough.
For example, if you are trying to solve a problem involving a block on an inclined plane, and constantly get confused on the direction of the forces involved, then you're not having trouble with the math, you're likely having trouble understanding forces and vectors and how to use them to set up your problem.
Also keep in mind that engineering encompasses a wide variety of fields and jobs, and even if you don't like a particular aspect of physics, perhaps statics or rotating objects, that doesn't mean you'll be a bad engineer. You may never even have to work with those depending on the career you choose. Just keep on doing the best you can and don't worry too much about whether or not you'll be able to pursue an engineering degree.
