1. 2-D Forces and Motion is a difficult unit. Did you figure out any "tricks" that made it any easier for you?
I made tricks when learning the different equations between horizontal and angled projectiles.
2. If you could go back in time and give yourself some advice going into this unit, what would that advise be?
I would advise myself to spend more time going over free body diagrams with angles.
3. If in 5 years from now someone was to mention 2-D Forces and Motion, what might you remember? (It does not need to be an academic answer.)
I would remember the riverboat problem. I think learning about the current and where the boat finishes its journey was interesting.
