TPJ Bryan Cramer 11-04-08 Period 4 Today’s Objectives: Daily Question, Late Work, Recorder’s Report, 0 Inc. Force Scale, and Lab. Papers handed out the Force and Motion Recorders Report that goes with the lab and will be handed in with the lab. Today we worked on the force and motion lab. The purpose of this lab was to find the relationship between the unbalanced force acting on the cart and the acceleration that the cart has. This lab was done by placing a cart on a track and measuring how fast it accelerated when being pulled by different weights attached to a string. We measured the speed with a motion detector and the computer. We put a 1000 gram weight on the car so the motion detector could pick up the sound waves better and the car was easier to read on the graph. After we tested the car on a certain weight we measured the acceleration and the pulling force. We did this 8 times increasing the weight by 50 grams each time. We then had to graph out how the pulling force and the acceleration of the cart related to each other based on our observations. We found that when the weight pulling the car was increased so was the acceleration and the pulling force. After taking the observations and making the graph we answered many question dealing with the graph and the relationship between pulling force and the acceleration of the cart. Here is an LMD of the cart during the lab.
