Ben Snyder Constant Velocity Lab To the Left: The Position Vs. Time graph Red: Run #1 Blue: Run #2 Green: Run #3 Purpose: To find what the slope of a position vs. time graph represents. Q.1) The Slope of the second run is greater than the slope of the first run. The first piece of evidence is in the data calculations themselves. In run number 1 the calculated slope 15 m/s which is considerably less than the slope of the second run which was at a swift 0.27 m/s. Also as you can clearly see

Uniform Acceleration Cedric C. Labasan Physics Department‚ De La Salle University St. Joseph Hall Room 404‚ 2401‚ Taft Avenue‚ Manila‚ Philippines cedric_labasan@dlsu.ph 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

time taken to reach 100 km/h for 2000cc mid-size category between Japan cars and Germany cars The line graph shows the information about the time taken for 2000cc mid-size cars from Japan and Germany cars to reach 100km/h. The Japanese cars acceleration was a bit slower than the Germany cars with the same engine capacity. The Honda Accord was clocked at 10.7 seconds when it reached from 0-100km/h. The second car was the Toyota Camry‚ scored a 12.5 second for its trial. The next car was the Nissan

Abstract: In this investigation‚ a mass was attached to a string and was swung horizontally for certain number of rotations (ten). The sole goal for this investigation was to find and verify the relationships between Centripetal Force‚ Frequency and Radius of circular path. In order to get relationships between the variables mentioned above‚ this experiment was divided into two parts. In Experiment A‚ the radius of the path (length of the string)‚ along with the mass was kept constant‚ and the relation
