Does the value of the oscillation amplitude affect your results? What mass values will you use for this experiment? After this data was collected we studied to determine the length of the period of each oscillation. Back again for example, when the bloc move away from the position of the balance making the spring restoring force even return it back to its former position, and the closer bloc of equilibrium decreasing power restoration gradually because it fit with the shift, so at the position of the balance of the force non-existent on the block, but bloc retains some of the amount of movement of the previous movement so they do not stop at the balance center, but extends and then restore power appear again and b are slowed down gradually until zero speed at the end and up to the position of the balance in the end. Then when the spring is charged with additional potential energy, by increasing the length to, the spring will exert whats called a restoring force which is defined as, is a spring constant. F=1/T This was proved experimentally with incredible accuracy. /Ordering (Identity) A toy maker requires a spring mechanism to drive an attached component with a

Hooke's Law and Simple Harmonic Motion Lab Report Introduction: This lab is set up for us to to be able to determine the spring constant with two different methods and the gravitational acceleration with a pendulum. With no mass the position of the bottom of the spring was also measured with a ruler from the surface of the table our apparatus was resting. In this experiment, we measured \(g\) by measuring the period of a pendulum of a known length. At t = 0, the particle is at point P (moving towards the right . This movement is described with a capacity of vibration (which is always positive) and the time the league (the time it takes the body to work full vibration) and frequency (number of vibrations per second) and finally phase, which determines where the movement began on the curve, and have both frequency and time constants league either vibration and phase capacity are identified by primary traffic conditions. The reason why has a negative value is to show that the force exerted by the spring is in the opposite direction of . when the mass increases the frequency decreases. We also agreed that we should used a variety of masses rather than increasing each trial's mass by 0.1 g.
