Metal Ball Lab: Partner: Nataly L. 2 meters sticks 2 metal balls (small and medium) 1 stop watch 1 physics text book Tape Measuring tape
 * Materials **

1. We taped the 2 meters sticks together and set up the ramp. 2. Time the ball as it went down the ramp. 3. Measure the distance. 4. Repeat it 5 times for each sized ball.
 * Procedure **


 * Data **

We can see a difference in time between the two balls. This is noticeable because the weight of the balls are different. As a difference in the balls are show so do the velocity, distance, and average differ one from another.  Part 3: The Difference between the two balls are substantial. We can see that because of the size and weight of the ball the velocity differs.

Overall: This was a good starting project to the year. I liked how everyone in the group was always involved and no one sat around and watched. Although this was a simple lab, there were many places where one could go wrong. As group we had to many times drop the ball down a rap, as we let go of the ball we had to start the stop watch. I believe that one of my faults was that i was unable to start the stopwatch at the right moment. This could have altered the result of our data. As a result we can conclude that not all of our data is exact. One way we can make this lab better is by focusing the attention on the ramp degree. Many times throughout the lab we had to alter the ramps location. This faltered with the test because we never were able to have a set height and degree.
