Today we had yet another exciting day of physics! We checked and went over our Physics Review Problems worksheet and then started the Acceleration of Gravity lab to see what the acceleration due to gravity is...well we all know (hopefully) that it is -9.8 m/s squared so we are pretty much just trying to prove it. Our homework for the weekend was to do problem #s: 30, 31, 33, 47, 49, 51, 77, 78 on pg 54 in our textbook.
Q.O.D:
you can tell when the weight was moving the fastest by looking at the ticker tape timer because the dots would be farther apart on the tape. We are going to calculate acceleration by using the dots distances and time intervals to find the average velocity and then we are going to graph that along with time. The slope of that graph (change in velocity/change in time) will give us the acceleration.
