Students will graphically determine the spring constant k using their knowledge of Newton's Laws of Motion and Hooke's Law and by determining the period of a weight on a spring undergoing simple harmonic motion. It is assumed that this lab follows a chapter lesson on simple harmonic motion. The lab will be introduced with a class discussion of the guided questions. Students will graphically determine the spring constant k using two different methods and compare them by finding the percent difference:. Measure how much the elongation of a spring changes relative to the elongation of a spring in equilibrium i. Record the value of elongation. Plot data in a graph of F s vs. Determine the spring constant from the slope. Observe a set number of oscillations 25 per time.

Hooke's Law implies hookes law and simple harmonic motion in order to deform an elastic object, like a slingshot, a force must be applied to overcome the restoring force exerted by that object. Clearly the elastic object stores energy that has the motlon to do work.
After the work is done the elastic object undergoes oscillation. If we plot this oscillatory behavior as the object's position versus time, then the graph represents simple harmonic motion. In this video, we will demonstrate an experiment that uses springs and weights to validate the concepts behind Hooke's law and simple harmonic motion. Before demonstrating how a spring behaves, let's revisit the concepts behind its oscillation. Imagine, applying a force to the spring, like a weight, that harmoniv it to stretch from its initial non-deformed position until an opposing please click for source force eventually balances it and equilibrium is established. Now, with the spring at its equilibrium position, if you introduce an external force and lift the attached weight to a certain height, you allow the spring to gain some elastic potential energy PE.
Now when you release the spring, it undergoes a periodic motion, known as simple harmonic motion.
Your free access has ended.
If plotted on a graph of position versus time, the motion yields the sinusoidal waveform of simple harmonic motion. The period of oscillation T is given by this formula, which shows that T is inversely proportional to k -- the elasticity constant, and mootion proportional to m -- the mass of the weight attached. Therefore, the larger the please click for source, the longer the spring would take to complete one cycle of oscillation. If hookes law and simple harmonic motion system was isolated - unaffected by external forces, the oscillations would go on indefinitely as the kinetic and potential energies, KE and PE, mottion be continuously converted to one another. But in the real world there are always some frictional forces that cause damping and therefore the spring will ultimately come to a halt.
Now hookes law and simple harmonic motion you have an idea about the laws that govern spring oscillation, let's see how to test them in a physics lab. This experiment consists of a spring with a known spring constant, a stand, a set of weights with different but known masses, a meter stick, and a stopwatch. Secure the stand to a solid foundation, such as a table. Attach the spring to the stand making sure there is enough room to stretch the spring without contacting the top of the table.
Using the meter stick, note the non-deformed position of the spring, or the distance between the bottom of the spring and the tabletop.

Make a note of this starting position on the meter stick. Now, starting with the smallest mass, calculate and record its gravitational weight. Attach the weight to the spring and measure the distance between the bottom of the spring denoting the equilibrium position and the starting position noted earlier. Record this displacement value. Next, raise the weight slightly from its loaded position and release it to observe simple harmonic motion. Using the stopwatch, measure the oscillation period by dividing the time required for multiple periods by the number of periods. Repeat this procedure three times to obtain an averaged period.]
You have hit the mark. In it something is also to me your idea is pleasant. I suggest to take out for the general discussion.
I think, that you are not right. I am assured. I can prove it. Write to me in PM.
