## Physics Report HOOKE'S LAW

Dynamics - Hooke's Law Experiment Physics 1 Dynamics Experiment How Does A Spring Scale Work? It is important to use the same part of the spring for this position measurement. Lab Tips: The force F applied to the spring can be measured in a variety of ways, using a number of different materials. It is performed simply by putting weights on the mass hanger. This would give us a better understanding of the experimental procedure and reduce the errors caused by the method. When the body undergoes an arbitrary displacement from some initial position, , to some final position, , this equation can be written as 2 where is the body's displacement. As each mass is hung, dampen the motion as best you can with your hand until the motion stops or becomes small enough that an accurate position measurement can be made. It should be noted that at amplitude of 0.

Graph Showing z Plotted Against x Looking at Fig 4. It states that when a force is applied to a spring, the displacement of that spring will be directly proportional to the amount of force applied. You can investigate Hooke's Law by measuring how much known forces stretch a spring. He was one of the most brilliant and versatile of seventeenth-century English scientists, who discovered the law of elasticity. After you have removed your finger from the sphere pull the sphere away from the charged strip. It is also possible to study the effects, if any, that amplitude has on the period of a body experiencing simple harmonic motion.

I find that they learn more when they make the mistake without my warning them first, rather than if I talk till I'm blue about it before hand. Year 11 Lab Report Template Experiment â€” Modelling A. To begin the investigation, the spring was attached to the ring stand. Perhaps if I had a teacher who so clearly explained what we were doing and why, as you did in the article, that outcome may have been different. I gave them springs that had been abused and no longer exhibit the linear behavior, but I never told them that. Robert Hooke was a 17th century physicist who discovered the relationship between the forces applied to a spring and elasticity.

Different trials were done in order to compute for the elongation x. The change in displacement of the spring and the weight of the hanging mass was recorded. In your notebook, record the spring constants determined by these two other groups. Posted on by This entry was posted in. If one hypothesis is not supported such as a linear relationship , it is nice if students can explore other possibilities and suggest an alternative hypothesis from their data.

It should be noted that at amplitude of 0. The spring then elongated with a certain displacement, and comes back to its normal length every time the mass was removed. This is not a team activity. There were four infants affected by this cluster. Force N data only, no headers into Graph.

Part of doing an experiment is the ability to handle things when something unexpected happens. Consequently, it takes some finite applied force to overcome the resulting internal tension and produce a measurable displacement. Subsequently, 2 more loads were added and the process of measurement was repeated. Do not check the box setting the y intercept to zero. The Figure also needs to be properly captioned and should be described in a paragraph of text 10 points.

Making a small pointer out of a bent paper clip and fixing it to the end of the spring has worked well for me in the past. Mathematics for Engineers, 3rd edition. State clearly the evidence for your answer. But this is unlikely in most 1 hour high school physics and physical science classes. When a mass, , is suspended from a spring and the system is allowed to reach equilibrium, as shown in Figure 2, Newton's Second Law tells us that the magnitude of the spring force equals the weight of the body,.

More specialized and more precise equipments that could measure up to at least 2 decimal points could minimize the relative influences of this error and improve the results enabling the slope to pass through the origin. This was something that could not be avoided; at that amplitude the spring pulled the hook up too quickly which caused the loss of contact. Theory An example of elasticity is a rubber band, as we stretch the rubber band, it changes its shape, removing the force applied to it, it will return to its original form. Hypothesis The change in length of spring is directly proportional to the applied so that it will cause greater change in length of the spring for greater force applied. Material 3, shown in the results as x, on graph Fig 5. Looking at the F versus x graph will show that this wonky spring did not show the same behavior as the Hooke's law spring.

However, if the vertical displacement is held constant while the applied force in increased, the period will increase. In doing so, we made sure that the spring and meter stick hang over the edge of the bench, where the experiment is being carried out. The floor beneath your feet works the same way. If the mass of the component is 10g, what must the value of the spring constant, , be? This was observed during the experiment. The experiment is set up so that you can change the mass of the sled, the value of the hanging mass, and the coefficient of friction between the sled and the surface supporting it. I think the biggest part in motivating accuracy is showing it can be achieved with due care at a few important points along the way.
