Open the simulation https://phet.colorado.edu/sims/html/masses-and-springs/latest/masses-and-springs_en.html  Select "lab”  Place the 100 g mass on the spring and wait for it to come to rest. Click the "mass equilibrium" checkbox to show the equilibrium position. Drag the ruler onto the simulation. Lift the mass and measure the amplitude (A).  Release the mass and use a stopwatch (either the one in the simulation or the one on your phone) to measure the time for 10 oscillations.  Do this for 3 different amplitudes (small, medium, and large).

The potential energy stored in C2 before the spring was released. c. The kinetic energy stored in the spring before the spring was released. d. The potential energy stored in the spring before the spring was released.

You want to measure the period of pendulum with a stopwatch.  Which technique will help minimize the error in the measurement? a. Measure the time for 10 swings across and back and divide by 10 b. Measure half of one swing across and multiply that time by 4. c. Measure one swing across and back, no multiplying is necessary. d. Do multiple measurements and take the average period. e. Both (a) and (d) will help.

Set the "Spring Constant 1" slider to its maximum. 3. Ensure "Earth" is selected in the Gravity field. 4. Set the "Damping" slider to its maximum. Natural Length Mass Equilibrium a. We're not considering springs in motion, so this will get the system to equilibrium quickly. Movable Line 5. Click the 'Displacement' option on the right. O Period Trace a. The blue dotted line represents the equilibrium position of the spring, where x = 0 m. Gravity 9.8 m/s? 6. Move the Mass slider down to 50 g, then place the 50 g mass on 30 the spring. 7. Convert this mass to the force of gravity (where F, = mg and 9.8 m/s2) and add this data to Table 1. Earth Remember to convert masses to kilograms for this Damping a. calculation. None Lots b. Note that this force is a vector. It's directed downward, so it's…
