please do all of the questions and everything that is being asked in the instructions. the phyphox app will need to be downloaded in order to obtain certain data for this assignment. this is due on Sunday, October 30th. thank you very much for your help in advance. photos and instructions will be attached below:

V km =ma$ Eq. 2 That is, the acceleration of the block (excluding the acceleration due to gravity) is proportional to its position, and the direction of the acceleration is opposite the direction of the displacement of the block from equilibrium. Systems that behave in this way are said to exhibit simple harmonic motion. An object moves with simple harmonic motion whenever its acceleration is proportional to its position and is oppositely directed to the displacement from equilibrium. If the block in Figure 1 is displaced to a position A and released from rest, its initial acceleration is -kA/m. When the block passes through the equilibrium position x=0, its acceleration is zero. At this instant, its speed is a maximum because the acceleration changes sign. The block then continues to travel upwards with a positive acceleration and nally reaches -A, at which time its acceleration is +kA/m and its speed is again zero. The block completes a full cycle of its motion by returning to the original position, again passing through x=0 with maximum speed. Therefore, the d2l.laurentian.ca CL lil Lab2_lnstructions-PHVS1006E - Introductory Physics I - Lab 1 Auromarlcmom v original position, again passing through x=0 with maximum speed. Therefore, the block oscillates between the turning points -A and A. In the absence of damping forces, this idealized motion will continue forever because the force exerted by the spring is conservative. The period T of an oscillation is the time to complete one cycle. It is always positive. The SI unit is the second. The angular frequency of an ideal oscillator is given by m = J; Eq. 3 Real systems are generally subject to damping forces. In such cases, the angular frequency becomes PHYS 1006E-Lab 2 Instructions Page 2 of 7 i Eq.4 , k m 4m2 \"7: where b is a damping constant that describes the strength of the damping force F x:- bvx.

For those with no spring, elastic rubber bands can be used instead. The phone has a dual purpose: it serves as an oscillating mass PHYS 1006E-Lab 2 Instructions Page 3 of 7 and serves as the sensor to track its motion as it oscillates back and forth. Use the accelerometer (Acceleration without g) in order to acquire the raw data, which is the actual acceleration of the phone without the gravitational acceleration.
