Kinematics
Measurement Review
Speed, Velocity and Acceleration
TI is usually, but not always, zero. |
The Four Formulas
Every kinematics problem will give you 3 of the 5 variables and ask you to solve for 1 variable. The fifth variable doesn't matter - use the formula without that variable (if the problem doesn't mention a, use the formula without a in it.) |
Example Problem
The equation without t in it is Δx = (VF2 + VI2) / 2a. Then, all that's left to do is to plug in all the variables and solve for VF! The answer to this problem should be 39.60 m/s. |

Kinematics Cheat Sheet (DRAFT) by pastel-galaxies
An explanation of the kinematic formulas, when to use each one, and the connections between acceleration, final and initial velocity, displacement, and time.
This is a draft cheat sheet. It is a work in progress and is not finished yet.
