Abstract This lab report defines what uniform acceleration is and how to calculate uniform acceleration of a cart rolling down a ramp at different angles and elevations. The experiment will be performed by setting the cart on the track against the end stop and then record this final position on the steel ramp ten times. Once the results are found you can calculate the percent error of the uncertainty values. The uncertainty value is the acceleration of the cart falling down. That value will be
