Physics class is something of astonishment. It's a class where as you're being taught the material you can see the effects working directly in front of you.
Don't believe me, well look for yourself! The physics room is full of physics itself.
Take a student for example. A student is sitting in a chair, what are the forces?
Well there's gravity acting upon him and everyone else pushing him and us towards the earth. Luckily that's not the only force or we'd be squished like a bug. There's a normal force of the ground(and the chair) pushing right back equal to the force pushing down. Even as you stand there now reading this post there are forces acting on you!
You can't escape the physics no matter where you go, even in space there will still be some physics applied!
