kinematics usually involves the 'Four Magic Equations' of motion.
Each one 'leaves out' one of the four 'variables', d, v, a, or t.
The one that is missing t is usually written
Vf^2 = Vi^2 + 2ad
but can also be written:
1/2 Vf^2 - 1/2 Vi^2 = a d
multiplying through by mass gives us
delta KE = F d which is a 'pretty good' intro of the Work Energy Thm.
