Hola, ya van tres veces que me cancelan mi profesor en mi desarrollo de práctica.Con el uso registro de información tablas. Necesito ayuda para desarrollar una practica de trabajo y energía en fisica clasica, tiene que ser cuantitativo. ¿alguna idea para grado de universidad? les entrego un ejemplo The spring is equipped with a distance scale, as shown in Figure 7.1, so that you can see the equilibrium point change as you change the weight of the object. The scale and pointer should be removed for Part B of the experiment. 1 Figure 7.1 Detail of the spring and scale of Figure 7.2 Photo-gate positioned to measure the Hooke's law apparatus (Part A) the motion of the object (Part B) The computer interface measures motion through a photo-gate (aka light gate). The Hooke's law apparatus hangs the object (weights) at the end of a spring, which cuts across the light path in the photo-gate on every downward swing, if positioned as shown above in Figure 7.2. Procedure Part A Adjust the pointer so that it is directing to readings on the scale of the Hooke's law apparatus. Record the initial value,

Add a 25 g weight to the hanger and record the new position of the pointer as the displaced equilibrium position

. Repeat step #2 (above) until Table 7.1 is completed, by adding 25 g and recording the new equilibrium position for every increment in mass. PART B From the desktop choose the "Simple Harmonic Motion" icon. Position the photo-gate so that it is just below the bottom of the mass. Start the system oscillating by gently pulling down on the mass and releasing it. Adjust the position of the photo-gate so that when the system is oscillating, the bottom of the mass interrupts the photogate but does not pass completely through the gate. This way the bottom of the mass starts the timer and, when it completes one oscillation, stops the timer. Stop the system oscillating and swing the photo-gate out of the way so that it does not interrupt the oscillating mass. Start the oscillations by gently pulling down on the mass and releasing it vertically. When the system is oscillating smoothly, with little sideways drift, swing the photo-gate in place under the spring so that the weights intercept the path of light every time the spring moves down to its lowest point. Choose "Play" on the computer interface to start the computer collecting data. Choose "Stop" when the data table is completed on the monitor. Record the average period displayed at the bottom of the table in the data table for Part B. 47 PART B (alternative) If you're using a stopwatch: start the system oscillating by gently pulling down on the mass and releasing it. When the system is oscillating smoothly use a stopwatch to time 10 periods of oscillation. Divide the time you measure by 10 and record it in the data table for Part B. Repeat steps 8 through 10 if you're using a computer, or step 11 if you're using a stopwatch, with masses of

and 200 g . Increase the mass by sliding the appropriate slotted masses on top of the 100 g hanging weight. For the 200 g trial you can use the 200 g hanging weight. With a 200 g hanging weight, observe the oscillations for some time as the amplitude slowly decreases. Do you notice any change in the period, or does the period stay roughly constant? Record your observation on the data sheet. CALCULATiON AND ANALYSIS Calculate the gravitational force
