"WebThe simplest way to measure velocity is to use a stop watch and a meter stick. Unless one is careless, human error can seldom be attributed to errors in experiments. However a stop watch is only as good as the human controlling it. At best, human reaction time is a fraction of a second (1/5 th) and this alone can create an error.

Set up a timer using one photogate - PASCO Capstone Help

WebPhysics students measure the acceleration due to gravity using a wide variety of timing methods. In this experiment, you will have the advantage of using a very precise timer connected to the calculator and a Photogate. The Photogate has a beam of infrared light that travels from one side to the other. It can detect whenever this beam is blocked. Web1. Set up your Table display so it shows the values of position, velocity, and acceleration. 2. If necessary, rescale the Graph to fit the data. 3.

The front of the paper card trips the photogate on, and the back of the paper card trips it off. The velocity calculated in this part is very close to the instantaneous velocity at that point. 1. Unplug (or if necessary, remove) the auxiliary gate.

WebIf we use a photogate, we can use a clear plastic with blackened marks at 0.01m increments and then the photogate will measure when it registers a ON pulse at every black mark and an OFF otherwise and will save the time it measured the pulses at. Then we just need to subtract the final time from the initial and we can calculate the velocity.
