The slope of the F versus x graph is called the spring constant, and is indicated by the variable k. The maximum displacement A is called the amplitude. 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. In addition to this, there is an experimental error of approximately 0. Weigh the 5 loads using an electronic balance and record them.

Lab 4 Lesson 8 Reflection Paper Details of the Participants Participant Age Gender Recognition Test A 33 M 17 2 B 30 F 13 3 C 54 F 10 4 D 63 M 8 The four participants that were chosen for this were selected all at once. All procedures were repeated using the other spring. You may even have seen these springs before. With a 2-meter stick, carefully measure the length of the string, including the length of the pendulum bob. What is the resulting slope with 90% confidence? This will enable us to have larger extensions of the spring. The value of k is constant for a particular spring.

The forces acting on the bob are the force of gravity and the tension force of the string. These results imply that a more supercritical upstream flow in D1, will produce a larger downstream depth, D2, and thus a larger hydraulic jump. Bring the sphere on the guide block near to the charged strip but do not touch them together. Winding the wire into a spring just allows us to exploit the properties of a long piece of wire in a small space. The unit of moment is the Newton metre Nm. Table of final length of spring for 100. Independent variable: The weight of the object.

Pay attention to the y-axis scale. Repeat the experiment and add 50 grams more each time. The floor beneath your feet works the same way. Since the spring used is the same, the spring constant will always be the same for any value of force applied and extension of the spring. This condition can exhibit lethargy, vomiting and not being able to breathe. It is the force constant of the spring.

When the spring is compressed or stretched the x value is positive. The deformation is reversible, non-permanent. This means, that the material after stretching can still come back to its original shape. This is figured in the final plot of W versus x. Back in the 19th century, Michigan forests became the resource on which the lumbering industry.

What are the mathematical relationships between these properties? The percentage difference of the average value of the force constant and the slope was calculated. After heating the salt crystal is called as anhydrous, which means without water. However, the spring sometimes was unstable as it moved up and down, especially when the weight was just added, making it hard to check the extension. The cuvettes are then placed into a spectrophotometer. This is a very useful relationship to understand when thinking about the properties of combinations of springs. Where did they come from? We recorded our values for extension of the spring as it is pointed out on the meter stick until we reached the 8th trial, which corresponds to the mass value of 700 g.

Discussion In the test for the engine parameters, it was found out that the temperature changes for ambient temperature, and fuel in the engine increased with time. Calculation table of the spring constant of spring for 30. Year 11 Lab Report Template Experiment â€” Modelling A. It is the time elapsed between any two instants at which it completely reproduces its motion. A mass hanger was then connected to the bottom of the Stretch Indicator. Just spot the best straight line fit and draw the line in with a ruler or run a linear least squares calculation.

Daphny Maldonado Bio Lab 2107 Kiah Britton W 10-12:30 Is H20 Bad for You? Independent variable: The weight of the object. With the sphere close to the strip, touch the sphere with your finger and then remove your finger. Hang a load at the hanging spring. The two first materials Figure 3 were clearly undergoing elastic deformation, while the third material Figure 4 showed evident plastic qualities. Note that the points fall precisely on the line since this is a virtual experiment.

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. This will later be our 1st trial. Also, through this experiment, students know some basic indexes to assess the efficiency of pumps used.
