bulletKey Terms and Equations
bulletuniform accelerated motion
bulletdisplacement
bulletdistance
bulletaverage velocity
bulletinstantaneous velocity
bulletspeed
bulletacceleration
bulletkinematic equations
bulletv2 = v02 + 2ad
bulletv = v0 + at
bulletd = v0t + (1/2)at2
bulletaverage velocity = displacement/time
bulletFree-fall
bulletacceleration due to gravity (g = 9.81 m/s2)
