How do the distance vs. time, velocity vs. time, and acceleration vs. time graphsfor a fan cart uniformly accelerating, from rest, compare with one another?Take time to answer the ‘What Do You Think?’ question(s) in the Lab Report section.BackgroundEquations for motion, given a constant acceleration (a), are:1 2Position: x = x0 + v0t + at2where x o and v o are the initial position and initial velocity. Note that if x oand v o are zero, the equation is a parabola.Velocity (1 st derivative of Position):dxdt= v0+ at = vNote that the 1 st derivative of position is the slope of the position vs. time graph. This equation islinear. The slope of the velocity vs. time graph is the constant acceleration. The acceleration canalso be written:2dxAcceleration (2 nd derivative of Position): a2dt=SAFETY REMINDERS• Keep hands clear of fan blades.• Do not let the cart run away from the user. Catch the cart before the cartcrashes into the bumper or travels off from the table.• Follow directions for using equipment.P04 ©1999 PASCO scientific p. 21
