Analyzing The Conservation Of Mechanical Energy Of A Harmonic Oscillating Spring System

Before the gymnast jumps on the springboard the board and springs have potential energy. When the gymnast jumps on the springboard it turns into kinetic energy and causes the board to push the gymnast up. The larger number of springs in the air board have more potential energy which leads to the hypothesis that it will provide the greatest

The pendulum was pulled to about 15 cm from the motion detector. In case of the mass on a spring, the mass was pulled till just a few inches away from the motion detector.

A. How did the experiment in Part I demonstrate surface tension? Use your experiment observations when answering this question.

Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change.

After collecting data and analyzing the results the group concluded that tension will always be greater than mass for uniform constant motion due to the presence of θ. As the length of the string for the flying toy increased, θ decreased in both trials for the cow and bat. For instance, when the bat had a length of 0.86m, the calculated θ was 34.4°, but when the length was shortened to 0.61m, the θ increased to 36.5°. The period was also shortened when the length decreased; therefore, velocity decreased as string length increased while acceleration increased with a

In addition to , the data of the major finds in the experiment were the control speeds or no sail had an average speed of 138.3 sail had an average speed of 127.3.Sliding friction data average was -252.4. Rolling friction data had an average was –30.21.

Locate the force string and use the hooked end to connect the force string to the other side of the spinning mass. Guide the force string over the pulley. Suspend the mass hanger plus an additional 0.55 kg of mass, so that m= 0.6 kg. Ensure that the weight hanger does not touch the table top. This hanging mass will be referred to as the force mass from now on, and is used to set the centripetal force, Fc. The force Fc is equal to the force mass, in kg, multiplied by gravity. Calculate this value and record it onto Data Sheet C. Adjust the tension knob so that the tip of the spinning mass is directly above the

scale. Use the pulleys to raise the load 10 cm. Measure and record the force

The main mechanical structure is modified version of the structure that is described in the [1,3]. The device consists of a proof mass which is attached to two similar double-ended tuning fork resonators via a force amplifier like a mechanical lever with a special configuration. This schematic of this structure is depicted in Fig. 1. Each of the DETF resonators is actuated to their resonance electrostatically and they will be sustained in their resonance by a feedback loop[17]. When an external acceleration is applied to the structure in proper direction, the proof mass will deflect and as a result of this movement an axial force will transfer to the DETF resonators. This axial force will result a change in the stiffness of the resonators so there will be a shift in the resonance frequencies of these DETF resonators[3]. These shift in resonance

A pendulum is a bob suspended by a string from a fixed point and behaves in an oscillating manner. When released from an angle away from its equilibrium, it swings side-to-side in a periodic motion. The time it takes to complete one full swing is considered the period and the purpose of this investigation is to discover the effect of the string length on the period of the pendulum. This will be accomplished by recording and analyzing data with the use of data tables and graphs.

As a result of trail and error method we find the angle for the third pulley and the mass that should had be suspended from it. This will balance the forces deployed on the strings due to the other two masses. While the third force is defined as the equilibrant (������⃗������) Since it is the force that establishes the equilibrium. It is also the negative of the resultant -������⃗������ = ������⃗������ = ������⃗ ������ + ������⃗������. We gathered and recorded the mass and the angle required for the third pulley to enable to put the system into the equilibrium in table 1.

Following tables and graphs show the result of the experiment. The tables will demonstrate the experimental and theoretical deflection for each case. The graphs will show the relationship between the load applied and deflection, in addition to compare the experimental deflection and theoretical deflection.

Table 1 & 2: First, find the mass of the wooden block and record the data. Then place the wooden block on the inclined plane (at 0o) with the wide side down. The height of the pulley should be the same height as the screw location on the wooden block. Then hang a weight on the opposite side of the hanger and add weights until block starts to move with a constant velocity (push block to overcome fs¬). Then record the resulted weight of the hanger in Table 1 (as F). Add 500 g to the wooden block and repeat the process. Replace 500 g with 1 kg on the wooden block. Repeat the process described above.
