Name: David Calderon TA: Jie Zhang Section: TH 7:35-9:25 Date: 03/05/09 PROJECTILE MOTION Abstract: Kinematics models on projectile motion follow Newton's laws of motion. This can be confirmed with the use of Newton's 1 st and 2 nd laws in experiments of projectile motion: 1. x = v x t 2. y = y 0 1 2 g t 2 ¿

I OBJECTIVE Verify or invalidate the kinematics model of simple projectile motion based on Newton's laws of motion. II PROCEDURE The equipment in this experiment required an apparatus consisting of an inclined plane connected to a a guided track with photogates 1 and 2 at the connecting and opposite end of the guided track, respectively. The guided track lead to a drop where a time of flight accessory (called photogate 3 for future reference) was on the floor and connected, along with the photogates, to a science workshop interface. Photogate 3 included carbon paper and a plain printer paper on its surface for reasons explained further on in this report. Before continuing, a meter stick was used to determine the initial height of when the ball would begin projectile motion. A ball is released from the incline 5 times from the same position so that it falls directly on the top surface of photogate 3. The science workshop interface

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
