Dwayne Dunlap September 10, 2008 Getting used to SI units Position, Velocity, & Acceleration Goals : To find out how position, velocity, and acceleration relate to one another and how they are used in the greater physics and how you measure them. Theory : In order to understand any of the basic laws we must first understand how each term, discussed in this lab, relates to each other. For example velocity is the position of an object with respect to the time it took the object to get there, assuming acceleration was zero. Or Δx/Δt = V avg. , and how the velocity of an object changes with acceleration or ΔV/Δt = a avg. . Procedure : Find a meter stick. Start measuring some lengths. After measuring lengths of about four or five different things set up the photogates so it is in the “U” position I meter apart, and turn it to pulse. See if you can move your finger at a velocity of 1 m/s, then 2m/s, then .5 m/s. After you familiarize yourself with these concepts it is time for you to use the rail, cart, and tape timer.

Set up the photogates on each end of the ramp to act as a support for the paper. Weave the paper through the tape time that should be on the cart on the ramp.
