A blank table of results was prepared so that results could be noted down in an organised manner Minimising Experimental Errors The ruler was carefully viewed from all angles to ensure that it was vertical unlike the one on the right.

Since mass also possesses weight a forcethe addition of greater amounts of mass hence translates into greater amounts of force. The points of both sets of results were plotted on the one graph.

In other words, things break down, and when those things are precision instruments or equipment, they require the services of very specialized technicians to restore them to their working order. The scale had to be viewed at eye level to avoid parallax error. With the help of the matching graph, can you use your spring to measure the weight of another object?

Everybody knows that when you apply a force to a spring or a rubber band, it stretches. An experiment to investigate the stretching of springs The equipment was set up as shown in the diagram on the right.

Mass gets pulled by gravity.

In this lab, measured quantities will probably be mass, starting position of the spring, and stretched position of the spring. If this is not carefully attended to and there are generally many quantities that could affect the results of an experiment the experimental results will be worthless.

The mass hanger was hooked under the pointer. For each spring, make a graph of the change in length of the spring in cm, y-axis vs. Divide weight by elongation in meters and record. In this lab, calculated quantities will probably be the stretching force, and the distance that the spring was stretched.

Generally, we want to know "What is the mathematical relationship between quantity A and quantity B? So, we could state the purpose of this experiment as "Is the stretch of a spring proportional to the applied force?

The mass values are just examples, and may be different for your springs. A pointer was used to help read the scale on the ruler. If you like this project, you might enjoy exploring these related careers: This gave us a scatter graph of the results.

Write an equation that expresses the relationship between applied force and elongation for each of your best-fit lines. Clearly, you need to measure both the stretching force and the amount of stretch - how much known forces stretch a spring. Extrapolation is the process whereby we extend an established numerical relationship between two variables beyond the limits of our observed and recorded data.

The elasticity constant, which is a constant of proportionality relating the amount of applied force required to produce a specific elongation, is specific to a particular material or object. Every physics experiment has a purpose, often phrased as a question that the experiment hopes to answer.

We can work out the weight exerted by the masses in our results by using the equation: A best fit line was plotted. Does the physical "feel" of the springs when stretched between your fingers support your determinations? Enter all observations in the data table provided.

You will never collect too much data, but there will definitely be times when you wish you had more. What sort of result - what sort of answer - would a physicist expect in an experiment? Record your elongation values to the level of precision permitted by the scale 0. Virtually every object that you see around has been mechanically engineered or designed at some point, requiring the skills of mechanical engineering technicians to create drawings of the product, or to build and test models of the product to find the best design.

Also make sure that the caddy is freely suspended, and does not contact the apparatus in any way. As you proceed in your study of physics you will learn some techniques that generally turn a Springs hookes law lab into an equation with a minimum of fuss.

You should have the data table ready to go when you enter the lab. It is important that you work carefully and precisely, but This relationship is to be tested both mathematically as well as graphically.

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. Ask an Expert The Ask an Expert Forum is intended to be a place where students can go to find answers to science questions that they have been unable to find using other resources.

Observe each elongation produced by each mass increment by noting the position of the wire pointer with respect to the vertical metric scale.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. Hooke’s Law 1. Purpose: The primary purpose of the lab is to study Hooke’s Law and simple harmonic motion by studying the behavior of a mass on a spring.

Your goal will be to extract a measure of the stiffness of one particular spring. 2. Theory. AP Physics - Experiment 1 Stretch and Force for a Spring In this case, there is a theoretical prediction (that we will make use of later) called Hooke's Law, that says that the stretch of a spring is proportional to the applied force (in symbols, F = kx, where k is a constant).

if you had a set of graphs that showed the relationship. The two springs will obey Hooke’s law until the upper spring has been stretched to its limit. For 1. Begin your lab report according to the ILP instructions about writing lab reports (ILP: “Laboratory Microsoft Word - mint-body.com 5 springs for Hooke's Law Demostrations This is a set of 5 springs with different spring constants.

The forces required for a 1cm extension are. Search the world's information, including webpages, images, videos and more. Google has many special features to help you find exactly what you're looking for.
