This rod would be used to break the photon beam in the Photogate sensor, and send a signal to the computer. I'm not able to just leave it out in the public since Reddit will take it down because of copyright, lol. program the reading from the first sensor was the initial velocity of the standard cart, and the reading from the second sensor was the final velocity of both carts. Water 200 20 30 9. A rod was used to push down the button on top of the plunger cart. When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity. v . Why or why not? The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. Overall the total energy (kinetic plus potential) is conserved. If your time is greater than it's supposed to be, your results won't make sense. Because momentum is conserved we can state that the final momentum of a system is equal to the initial momentum of a system in the following equation. There are multiple possible sources of error in this experiment. Final Lab Report: Solar Cookin' - Suffolk University The experiment was executed by dropping three different balls of different masses at 100, 75, 50, and 25 centimeters. In the presence of nonconservative forces (like friction), the total mechanical energy is, In the presence of nonconservative forces (like friction), the total mechanical energy is not conserved.
