## Experiment with a spiral spring lab report

Various hooked masses. The most difficult parameter to analyze is the acceleration. Objectives Use the apparatus and what you know about Hooke's Law to determine the spring constant, , of your spring. This is done for the case of the oscillating spring-mass system in the table below and the three functions are shown in Fig. As the stiffness of the spring increases that is, as increases , the period decreases which has the effect of increasing the body's average velocity. Support stand and hook Figure 8. It helps to use Newton's second law, which tells us that a negative maximum acceleration occurs when the net force is negative maximum, a positive maximum acceleration occurs when the net force is positive maximum and the acceleration is zero when the net force is zero. Position D: The mass is in upward motion as it passes through the equilibrium point. It should be noted that the period of motion is independent of the amplitude of the oscillations. Conversely, an increase in the body's mass means the period will also increase, thereby requiring more time for the body to move through one oscillation. Use the apparatus and what you know about oscillating spring-mass systems to determine the spring constant, , of your spring. The equilibrium position for a spring-mass system is the position of the mass when the spring is neither stretched nor compressed.

It should be noted that the period of motion is independent of the amplitude of the oscillations. Position B: The mass is in downward motion as it passes through the equilibrium point. The body will move back and forth between the positions and. The mass completes an entire cycle as it goes from position A to position E. Mass pan Figure 9. Remember, do not suspend more than ! The most difficult parameter to analyze is the acceleration. The initial position of the body attached to the spring is 0. Here the spring is stretched to the 0.

Remember, do not suspend more than ! Figures 11 and Therefore, the positive direction in this case is down and the initial position A in Fig. Figure 2: Five key points of a mass oscillating on a spring. Consider several critical points in a cycle as in the case of a spring-mass system in oscillation. Here the spring is stretched to the 0. When the mass travels from the maximum displacement to the minimum displacement and then back to the position , we say that the mass has moved through one cycle, or oscillation. Mass pan Figure 9. It should be noted that the period of motion is independent of the amplitude of the oscillations. Objectives Use the apparatus and what you know about Hooke's Law to determine the spring constant, , of your spring. Figure 2 shows five critical points as the mass on a spring goes through a complete cycle. This is a basic property of any object undergoing simple harmonic motion. Do not suspend more than grams from the springs; doing so will deform the springs! This motion is periodic, meaning the displacement, velocity and acceleration all vary sinusoidally. Position B: The mass is in downward motion as it passes through the equilibrium point.
