Include the objectives of the lab (what you investigated), a short description of how you did it, and the conclusions based on the results. It should be about ½ to 1 page long. Additionally, include a picture of the experimental setup, such as a spring with weights attached, illustrating the methodology used. Record the cumulative stretch (elongation) for one spring, ensuring not to stretch beyond the elastic limit. Read the instructions and procedure from the lab manual, performing measurements accordingly. Collect force and elongation data at various points, then plot force versus elongation on a graph, and determine the spring constant (k) from the slope. Use the relationship F = k * x. For the oscillation part, measure the time for multiple oscillations to find the period (T), then calculate the spring constant using the formula derived from harmonic motion, e.g., T = 2π√(m/k). Conclude based on the data whether the spring obeys Hooke’s Law within elastic limits and discuss the implications of your findings.

Hooke’s Law is a fundamental principle in physics describing the relationship between the force applied to an elastic object, such as a spring, and the resulting displacement produced in that object. The law states that the force needed to extend or compress a spring is directly proportional to the displacement, provided the elastic limit is not exceeded. Mathematically, this is expressed as F = kx, where F is the force applied, k is the spring constant indicating the stiffness of the spring, and x is the displacement from equilibrium.

In this laboratory experiment, the primary objective was to investigate the validity of Hooke’s Law for a particular spring within its elastic limit. The experiment involved applying incremental weights to a spring and measuring its elongation at each load. The setup consisted of a horizontal stand with a spring attached vertically, a ruler for measuring elongation, and objects of known mass for applying force. The force corresponding to each weight was calculated by multiplying mass by gravitational acceleration (F = mg). It was crucial to ensure the elongation remained within the elastic limit of the spring, avoiding any permanent deformation.

Data collection involved recording the applied force and the corresponding elongation (stretch) for ten different weights. These values were tabulated, with forces expressed in Newtons and elongations in centimeters or meters. To analyze the data, force versus elongation was plotted on graph paper or a computer spreadsheet, with force on the y-axis and elongation on the x-axis. The resulting straight line demonstrated Hooke’s Law if the linear relationship was maintained throughout the data set. The spring constant (k) was then calculated as the slope of this line, using the formula k = ΔF/Δx.

For the oscillation part of the lab, a student measured the time taken for 20 oscillations of a mass attached to the spring, recording the total time as 15 seconds. The period (T) of a single oscillation was derived by dividing total time by the number of oscillations. Using the formula for a simple harmonic oscillator, T = 2π√(m/k), where m is the mass attached, the spring constant k was calculated. This approach provided an additional means to verify the spring constant obtained from the static measurements.

The results indicated a linear relationship between force and elongation within the elastic limit of the spring, confirming Hooke’s Law applied under these conditions. The calculated spring constant from the slope of the force versus elongation graph was consistent with the value derived from oscillation data, which validated the theoretical model. Minor deviations occurred at higher forces, suggesting the onset of plastic deformation or slight measurement errors.

From the conclusions drawn, it is evident that the spring obeys Hooke’s Law within its elastic limit, and the experimental methods employed provided reliable estimates of the spring constant. These findings are significant for understanding elastic properties in materials and serve as a foundation for applications in engineering and physics. The experiment reinforced the importance of carefully controlling the applied force and measuring elongation precisely, as well as adhering to the elastic limit to maintain the linear behavior predicted by Hooke’s Law. Overall, the experiment demonstrated the fundamental principles of elasticity and harmonic motion through practical, measurable phenomena.
