Purpose: The purpose of this experiment was to explore the laws of conservation of momentum as well  as the conservation of energy using muzzle velocity and a pendulum.  Theory: Using the ballistic pendulum to measure the launch velocity of a projectile upon collision and  before, we can demonstrate conservation of momentum and conservation of energy. This  means that the total amount of momentum before collision is the same as the total amount of  momentum immediately following the collision.   Procedure: Load the launcher with the ball using the push rod to ensure that it is in place. Return the pendulum to the normal hanging position. Start data collection. Launch the ball so that it is caught in the pendulum

Unformatted text preview: • When the pendulum swings out and then back, stop data collection • Record the maximum angular displacement of the table. • Repeat steps 1-6 several times. • Look at the table to find the average maximum displacement Uncertainty: I think that this experiment had very little uncertainty or chance for error. One possible source could be from any added momentum that could be attributed to the rod having some mass. Conclusion: Using the laws of conservation of momentum and the laws of conservation of energy we can demonstrate how energy is conserved and transferred from potential energy to kinetic energy as well as to thermal energy....
