d2x/dt2 is integrated twice with acceleration held constant‚ it yields two integrations: x = x0+v0t+1/2at2 v = v9+at These two expressions show the relationship between position‚ velocity‚ and acceleration at a given time. Newton’s 2nd law states that the acceleration of an object depends on the net force acting upon the object and the mass of the object. If there were no friction in this experiment‚ then the acceleration of the glider would be equal to acceleration of gravity multiplied

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

PHY 114 Faraday’s Law of Induction Stephanie Scott Section: 10849 Group #3 Bochao Li 3/31/15 Abstract: The objective of the Faraday’s Law of Induction lab was to verify Faraday’s law of induction by measuring the emf generated in a small coil and comparing it with the calculated value. Secondly the goal was to investigate the relationship between the emf and the frequency of the driving signal. The magnetic field was found to be uniform throughout. For the frequency of 40 Hz‚ the average
