I just started learning kinematics in my college physics class and I am pretty thrilled. Question is am I supposed to be making sense of the mathematics in the equations? Because I feel like I'm just regurgitating formulas and I don't really think that's what science is about. For example, one of the kinematic equations is D=Vi(t)+half of(a)(t)squared. I want to understand why the time is squared at the end and why is it even divided by one half in the first place?
