Bryan Jacobs Mon 7-9PM Lab Partner: Cameron Rison Introduction: The main objective of lab 6 is to test whether energy is conserved in simple harmonic motion under the influence of a spring by proving that in its rotation the total energy of the system will be conserved and that an object under the influence of a force will experience an acceleration in the direction of that force. For this case we used two identical springs and one air puck in order to minimize the friction against the table. Because a spring obeys Hooke’s law, F=-kx, we know that any object under the influence of a net force will experience an acceleration following the direction of the force. T is the period, the time it takes each revolution (1/ Δt(s)) according to our sight. is the initial value of the angle related to the initial position by the radius. To record Ө the position we used a spark generator and the puck will travel its path and the position will be recorded in a paper with a variable interval in Hz, we used 20 Hz, which means a spark each 0.05 seconds (Δt). A(in meters, largest value from x(n) to x=0, taken to the absolute value) was the largest xn value, which were the distances away from the origin. Note that the x(m) values to the left of the origin. We saw an oscillation on the lab is because the force exerted on the spring to begin the experiment was stored as potential energy (U=1/2 kx(m)^2) (J). K, the spring constant gave us the strength of the spring, was calculated by k=ω^2*m(in N/m). Although we had two springs, they were of equal strength and the center of the puck was when they were equally stretched, so there would be no potential energy at the center of motion. The potential energy, when decreasing, turned into kinetic energy, in which we later calculated. W is the angular speed (m/s) and can be obtained by w=2π/T,

    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.
