Physics lab report 6 essay physics lab report#6 analyzing stress and strain using hooke's law name: fei huo date performed: november 5st, 2014 period 5 teacher: mr glasel purpose: the purpose of this lab was to examine the relationship between force and the elongation on two different springs and a rubber band. Rubber band wear is a short term effort for a lifetime goal they are instead of more aggressive therapy in fact, they are usually the most gentle, conservative and rapid way to get big amounts of tooth movement. The rubber bands in freezing water were the opposite, with a stretching length of 950 +/- oo5 cm (0 c) the results were consistent, providing a reliable conclusion to the project thermal expansion caused the rubber bands to react as they did. Question: how will the stretching of a rubber band affect the amount of energy that springs out of it hypothesis: if the rubber band is stretched more and more, then it will spring out farther because there is more energy in it with it being at its most since the more you stretch the more elastic energy is stored. Some elastic materials such as rubber bands and flexible plastics can function as springs but often have hysteresis this means the force vs extension curve follows a different path when the material is being deformed compared to when it is relaxing back to its equilibrium position.
The concept of elastic energy is similar to that of a stretched rubber band when the band is stretched there is a build-up of stored energy, which when released causes the band to rapidly contract back to its original shape. Factors affecting the stretching of springs and rubber bands essay by sarahkazim , high school, 10th grade , july 2004 download word file , 7 pages download word file , 7 pages 50 8 votes. A linear spring is a spring where the force that stretches the spring is in direct proportion to the amount of stretch that is, the force vs extension graph forms a straight, positively sloped line that passes through the origin, like this.
A rubber band and a copper wire both stretch under tension, but there is a fundamental difference between the underlying mechanisms of the two cases in the case of the copper wire. In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it rubber bands for energy. Place the rubber band flat on a table and mark two lines from where the rubber band's elasticity will be measured then measure the length of the rubber band within the marks just drawn next, observe the 1000ml beaker and convert the distance the rubber band could stretch from ml to cm. The factors affecting the stretching of springs and rubber bands scientific knowledge: before doing the experiment i came to the conclusion that this experiment relates to hooke's law which states that extension is proportional to the load, meaning that if you stretch something with a steadily increasing force, then the length will increase.
The physics of bungee jumping is an interesting subject of analysis the basic physics behind this activity is self-evident will affect a, k is the spring. Introduction if it is not stretched to the point where it becomes permanently deformed, the behavior of a properly wound coiled spring, when subjected to a stretching force, can be. Ð•if spring scales are not available, use rubber bands along with metric rulers to measure the stretch of the rubber bands it is not essential to measure in standard units (newtons, grams or pounds. Teachers often use the image of a rubber band to describe muscles when you stretch a rubber band, it usually returns to its normal size if you continuously pull it beyond the maximum that it can be stretched, the rubber band stays stretched out. Factors that may affect the experiment are: the thickness of the band the length of the band the amount of weights added to the rubber band.
Factors affecting the period of an oscillator class practical the experiment involves isolating and controlling one variable at a time, taking measurements carefully and drawing numerical conclusions by comparing sets of measurements. Mass and tension: any object that can vibrate is capable of creating a tone two factors determine the frequency of the vibration: the mass of the object and its tension as the mass is increased, the frequency and hence the pitch decrease. • shoot a rubber band by hooking it on the front edge of the ruler, then stretching it back to 10 centimeters (cm) on the ruler and letting the rubber band go.
Hooke's law is a principle of physics that states that the force (f) needed to extend or compress a spring by some distance x scales linearly with respect to that distance that is: =, where k is a constant factor characteristic of the spring: its stiffness, and x is small compared to the total possible deformation of the sp. What factors affect the pitch and loudness of the sound produced by the rubber bands the factors that may affect the pitch and loudness are the thickness of the string and the way you pluck the band either smooth or rough 5. Aim: to investigate the factors affecting the stretching of springs and rubber bands scientific knowledge: before doing the experiment i came to the conclusion that this experiment relates to hooke's law which states that extension is proportional to the load, meaning that if you stretch something with a steadily increasing force, then the length will increase steadily too.
