Unformatted text preview: John Brewer Lilly Force Constant & Work Energy PHY 241 Lab February 26, 2008 Purpose: The purpose of part 1 of the experiment is to determine the work of the cart and block on the Atwood machine. The coefficient of friction of the weighted block system will be found. In part two we will find whether k is constant and calculated the force constant of the spring. Materials: Part 1 Photo gate Timer Ramp Block with string Pulley wheel Weights Cart Part 2 Video camera Grid chalkboard Marble Launcher Meter stick Procedure: Part 1 The Atwood machine was constructed at an angle of zero degree. The cart was weighed with the block attached and the mass was recorded. The block was weighed and its mass was recorded. The string was draped over the wheel and 50 grams was added to the loop. The cart was attached to the other end of the string. A photo gate was placed at the 10 cm mark on the track. The cart was pulled back to the 50 cm mark on the track. When the cart was released it traveled 40 cm to the photo gate where the velocity was mark on the track....
