I need part 1, 2, and 3 answered please just google PhET Masses and Springs Simulations Lab and click the first link. The preview of the lab should be in a box click the arrow/play button in the box and the lab will open
2. Vectors At the base of your screen select ‘Vectors’. This helps in visualizing all vectors at play in oscillation. Select ‘Displacement’, ‘Mass Equilibrium’, ‘Velocity’, ‘Acceleration’, ‘Gravity’ and ‘Spring’. For first run leave Gravity as Earth. Attach 250g mass and observe vectors during oscillation.
(a) At which point is velocity minimum or zero?
(b) At which point is velocity maximum?
(c) At which point is acceleration zero?
(d) At which point is acceleration maximum?
(e) Is Gravity ever zero?
(f) Is spring force ever zero? When?
(g) What happens when Spring constant is increased?
(h) What happens when Gravity is changed to: (1) Moon (2) Jupiter (3) Planet X
(i) Determine value for gravity on Planet X.
3. Lab
At the base of your screen click on ‘Lab’.
Check boxes at top right corner for ‘Natural Length’ and ‘Equilibrium Position’. Select ruler and stopwatch for linear and time measure respectively.
Set Spring Constant and Damping such that Spring Constant is greater than Damping. Select known 100g mass and attach it to Spring. Adjust mass measure to value greater than 250g.
Press red stop button at the side of Spring to stop oscillations.
Pull mass downward away from its equilibrium position for an extension between 10 cm and 20 cm and release to begin oscillations.
What can be concluded from the results?
