Weak or easily stretchable bodies possess a low elasticity constant whereas strong or resistant bodies possess a high elasticity constant. Check how accurate your measurement is by weighing the object on the kitchen scale.

Briefly explain what this means and how your data illustrate this. The slope of each line is equal to the average elasticity constant for each respective spring.

These points indicated a trend of proportionality so a smooth straight line was drawn. Use your graph to determine how much the object should weigh.

This means that the extension of a spring is directly proportional to the stretching force applied to it. The title of the graph indicated what the experiment involved - it did not just say what was plotted angainst what - that could be seen from the labelling of the axes! You will never collect too much data, but there will definitely be times when you wish you had more.

It is important to record all of the readings taken and to show clearly any calculations we do from those readings.

Briefly explain why it is absolutely necessary that such elements function elastically. With the help of the matching graph, can you use your spring to measure the weight of another object?

After all twelve data points for each spring have been plotted, sketch-in a "best-fit" line which averages or normalizes the points to a single linear function.

What is the spring constant k for each spring? Record your elongation values to the level of precision permitted by the scale 0.

Be sure that you keep your original data. Enter all observations in the data table provided. In this case, the very best result would be an equation that expresses the mathematical relationship between force and stretch for a typical spring.

Extrapolation is the process whereby we extend an established numerical relationship between two variables beyond the limits of our observed and recorded data.

We therefore needed four columns. The experimenter had to be sure the spring system was stationary before a reading was taken. Columns should be clearly labeled, with units. Anomalous results were plotted, circled and repeated. We can work out the weight exerted by the masses in our results by using the equation: To calculate the change in length, subtract the average length of the spring with no weight 0 g from the averaged measured length for each of the other weights.

A best fit line was plotted.Virtual Hookes Law Lab - killarney10mile.com Hooke’s Law College Physics Lab. PH Hooke's Law and the Work done by a Spring. Purpose: To verify Hooke's law for springs, and determine the spring constant which characterizes the force exerted by a spring.

To verify the relationship the amount of. Abstract Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs?

Hooke's Law and Its Application to Springs. Laboratory No. 4. Introduction.

Mathematical Expression of Hooke's Law. The relationship between an applied tensile force to an object and its observed elongation can be simply stated as.

Force = Elasticity Constant x Elongation. After watching this video, you will be able to explain what Hooke's Law is and use the equation for Hooke's Law to solve problems.

A short quiz will follow. Hooke's Law Lab Summary. Use a force sensor and two springs to determine both Hooke's law and the spring constant of each spring. Theory. Students use two different springs to determine both Hooke's Law and the spring constant of each spring.
