All Students Difference and Average etc.

Many of you still confuse delta v and vaverage. You must understand this now.

vaverage = delta x /delta t

delta t = delta x/ vaverage

if a is constant vaverage = (vf + vi)/2

delta v = vf MINUS vi

delta t = delta v/a
Also delta x does not ever = a delta t and delta t does not ever = delta x/a
