This lab is to help us learn about how the change of force affects speed, change in radius affects speed, and how much force you need to use to equal different radiuses. First we took data by swinging a .0205 kg weight at different constant forces and timed how long it took to go around twenty times to measure how force affects the speed. We did this at six different amounts of force. We found that the more force applied the faster the weight travels. Next we compared how the length of the radius changes the speed when going at a constant force of two Newtons. We discovered that if you make the radius longer it will take a longer time for the weight to go around twenty times. Last we tested how much force we would have to apply to get a certain time based on how long the radius is. After collecting all of our data we had to make graphs to show how the things we compared are affected by the others. Each graph should have been close to a straight line. Next we had to square one of the columns of data to make the line the points on the graph make curved. Finally we had to decide whether the graphs were one of three types of graphs. They are a quadratic graph an inverse graph and a linear graph.
