Kinematics Slide Presentation - How to choose and use the correct Kinematic

Kinematic Equations

Only used when an object is accelerating

vf = vi + at	← missing d
vf2 = vi2 + 2ad	← missing t
d = vit + ½at2	← missing vf
d = (vi + vf)t/2	← missing a

Choose the kinematic equation based on:

• what quantities you are given
• what quantity is asked for
• what quantity is not involved
