The first three equations i was given is as follows:
Vf = V0 + at
Vf^2 = V0^2 + (1/2)at^2
x = V0*t + (1/2)at^2 [why do they sometimes use y instead of x or V0,y?]
I don't understand in what situations i would use them in nor do i understand why you us V=gt or X=Vx*T. (i understand g can is 9.8 m/s.)When and why do you use these equations? What are they supposed to mean?
