First Report Thur 18 Jan Spit wad Lab[edit]

I am inserting this b/c you and 24 seem to be working so well together.

First report Thu 18 January 2018 spitwad[edit]

In the physics lab, a basketball is pushed at a constant force as it passes evenly spaced out markings. Students will be working together doing different jobs such as ball pusher, timer, and spitwaders. As the ball is being pushed, the timer will yell out as every second passes and spitwads will be fired at the current position of the ball. After six seconds of this being repeated, students will then take a meter stick and measure the distance from the start to the origin of the grouped spitballs. With all the positions of the ball marked times

second Report Thur 25 Jan ping pong Lab[edit]

For this lab we are trying to determine if air drag is part of the forces slowing down a ping pong ball as it rolls. To determine this we set up a hot wheel track with one end lifted up and rolled a ping pong ball down. We marked were the ball was at every second for three seconds. We then used the differences in the distance between each marker to find the acceleration. Since a=(v2-v1)/t we had an acceleration of -7cm/s^2. We repeated the experiment and got similar numbers.
