Marko Mladenovic [email protected] Lab 132 Phys 106 3/10/11 1. OBJECTIVE The objective of this lab is to calculate and measure the velocity of projectiles of different sizes. They start of rolling from the top of an incline and falls off the table onto the floor. 2. THEORETICAL BACKGROUND Rolling motion combines linear motion with rotational motion. So kinetic energy of a rolling element includes both linear and rotational kinetic energy. At the top of the incline there is 0 kinetic energy and at the bottom there is no potential energy. 3. EQUIPMENT Hallow Cylinder, Solid Cylinder, Ball, 4. COLLECTED DATA h (cm) x(cm) y(cm) V (eq. 6) % diff. Ball m = 31.45 g r = 11 mm 84 138.2 92.5 3.18m/s 3.42m/s

Unformatted text preview: 6.4% Solid Cylinder m = 48 g r = 4.75 mm 84 134 92.5 3.08m/s 3.31m/s 6.9% 6. DISCUSSION 1. In this lab, we assume there is no friction. However in reality, friction always exists. The actual velocity is larger or smaller comparing to the one determined by assuming no friction? The velocity will be greater when we in include friction. 2. We assumed there is no slipping between the rolling element and the surface so that v = ϖ R. If there is slipping, the velocity will be larger or smaller? Marko Mladenovic [email protected] Lab 132 Phys 106 3/10/11 7. CONCLUSION We found velocity with to different equations. And found the percent differences for the two....
