Thomas Edison State College Physics with Labs (PHY-115) Section no.: OL009 Semester and year: AUG 2015 I. Introduction The purpose of this lab exercise is to calculate the acceleration of a rolling object down an inclined plane, in this case a marble is used. In doing so, the repetitive method of rolling a marble down a ramp multiple times, and calculating the time in which the marble hits each mark on the ramp, can then allow us to determine the velocity and acceleration of the marble when it hits each exact point on the ramp, as it rolls down the inclined plane. II. Data & Results Questions 1. 40cm 2. All marks = 77 degrees 3. The forces that are acting on the marble as it travels down the ramp are of a gravitational force along the ramp, as well as a regular gravitational force on the ramp which is balanced by a normal reaction. 4. The acceleration was almost the same for the first and third trials, and faster than the first and third trials for the second trial. 5. No, because the marble will speed up until it reaches its maximum velocity, and

    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.
