Experiment 8 Conservation of Energy and Momentum Mukesh Ghimire Lab Partner: Liam Abstract The main objective of this experiment was to determine the speed of the ball as it leaves the ballistic pendulum using the principles of conservation of linear momentum and conservation of energy. The equipment required for this experiment were a ballistic pendulum, 30 -cm ruler, triple beam balance, C-clamp, and safety glasses. When the ball is fired to the pendulum, there occurs an inelastic collision. Assuming the pendulum and the ball as a point mass, laws of conservation of linear momentum and laws of conservation of energy were used to determine the speed of the ball. The major sources of errors in this experiment were due to the facts that the ball and pendulum in fact were not point masses, the loss of energy as heat and sound due to friction between the ball, pendulum and the air. Results nd Velocity (2 detent) = 3.88 m/s rd Velocity (3 detent) = 5.25 m/s nd Energy dissipated (2 detent) = 79% rd Energy dissipated (3 detent) = 79% nd rd The velocities at 2 and 3 detent in this experiment were fairly similar to that determined in projectile experiment. The 2 nddetent velocity in projectile motion was 3.64 m/s and 3 rddetent velocity was 4.58 m/s. Since same ballistic pendulum was used for both the experiments under similar conditions, the values were similar to each other. Sample Calculations Mass of the ball and pendulum = 313 gm Mass
