<span style="font-family: 'Century Gothic','sans-serif'; mso-fareast-language: ZH-CN;"> When comparing the two sets of data it is made evident that the bigger ball has a greater velocity than the medium sized ball. According to the tables the small ball traveled similar distances to the medium sized ball but in less time. Based on the data from Table A and Table B we can evaluate their figures. The average velocity of the medium sized ball in Table A was <span style="font-family: 'Century Gothic','sans-serif'; mso-fareast-language: ZH-CN;">.9146 <span style="font-family: 'Century Gothic','sans-serif';">m/s whereas the small sized ball in Table B shows a velocity of 0.873. Due to these calculations there is a clear correlation between the size of the ball and the velocities. I have concluded that smaller objects have smaller velocities. <span style="font-family: 'Century Gothic',sans-serif;"> <span style="font-family: 'Century Gothic','sans-serif';"> <span style="font-family: 'Century Gothic','sans-serif'; mso-bidi-font-family: 'Century Gothic'; mso-fareast-font-family: 'Century Gothic'; msobidifontfamily: 'Century Gothic'; msofareastfontfamily: 'Century Gothic'; msolist: Ignore;">1. <span style="font-family: 'Century Gothic','sans-serif';">Find a clear and open space <span style="font-family: 'Century Gothic','sans-serif'; mso-bidi-font-family: 'Century Gothic'; mso-fareast-font-family: 'Century Gothic'; msobidifontfamily: 'Century Gothic'; msofareastfontfamily: 'Century Gothic'; msolist: Ignore;">2. <span style="font-family: 'Century Gothic','sans-serif';">Using the 2 meter sticks, tape, and the physics textbook make a ramp <span style="font-family: 'Century Gothic','sans-serif'; mso-bidi-font-family: 'Century Gothic'; mso-fareast-font-family: 'Century Gothic'; msobidifontfamily: 'Century Gothic'; msofareastfontfamily: 'Century Gothic'; msolist: Ignore;">3. <span style="font-family: 'Century Gothic','sans-serif';">Choose either a small or medium ball, and then roll it down the ramp.

<span style="font-family: 'Century Gothic','sans-serif'; mso-fareast-language: ZH-CN;"> <span style="font-family: 'Century Gothic','sans-serif';">Looking at the data from Part II there is a clear association between the size of the ball and the acceleration. Like proven in Part I, the velocity of the bigger ball was greater than the smaller ball. When using the numbers from these two tables to calculate the acceleration it was clear that the smaller ball would have the lower acceleration rate. The distance traveled was the same for both the small sized and medium sized ball, however the outcome was different. Based on the calculations from Table C, which measured the medium sized ball, the average time was .99s, the average velocity was 0.935, and the average acceleration was 0.945 <span style="font-family: 'Century Gothic','sans-serif'; mso-bidi-font-size: 10.0pt;"> m/s <span style="font-family: 'Century Gothic','sans-serif'; mso-bidi-font-size: 10.0pt; mso-fareast-language: ZH-CN;">2 <span style="font-family: 'Century Gothic','sans-serif';">. When studying the data in Table D, for the small ball there was a definite change in statistics. For Table D the average time was 1.08m/s, the average velocity was 1.08m/s and the average acceleration was 0.857 <span style="font-family: 'Century Gothic','sans-serif'; mso-bidi-font-size: 10.0pt;"> m/s <span style="font-family: 'Century Gothic','sans-serif'; mso-bidi-font-size: 10.0pt; mso-fareast-language: ZH-CN;">2 <span style="font-family: 'Century Gothic','sans-serif';">. When comparing these two tables it is evident that size of the object and velocity rates have a relationship, and size and acceleration have a relationship, then it can be declared that velocity is also related to acceleration. In conclusion, based on the data collected and recorded, there is an apparent correlation between the size of the ball and the acceleration, as larger objects have a greater acceleration rate. <span style="font-family: 'Century Gothic','sans-serif';">This lab was able to prove the concept that the size of an object affects its velocity and acceleration. The bigger the object the greater the velocity and acceleration rates it has. <span style="font-family: 'Century Gothic','sans-serif'; mso-fareast-language: ZH-CN;">The reason that the smaller ball was traveling at a faster pace was because it has less friction than the bigger ball. <span style="font-family: 'Century Gothic','sans-serif';">This lab was successful however; there may have been some inaccuracies when entering the data. These imprecision’s could have come from starting dropping the ball a different places on the meter stick, holding the meter stick in different ways when rolling the ball, and starting and ending the stopwatch too much before or after the ball has rolled. To act upon these inaccuracies I would improve some things for the next time. If I were to repeat this lab I would make sure that the ramp would stay at the same place for all the trials, for Part One I would also do more trials to make sure that my average velocity was more precise, I would make sure I measured the distance the ball traveled more precisely, and I would make sure that the stop watch was started and stopped at almost exactly at the points when the ball starts and stops. Overall, although this lab could have many improvements it was still extremely successful. In conclusion, this lab was able to confirm and demonstrate the relationship between size in relation to velocity and acceleration.
