Lab-9 SHM Online

P h y s i c s L a b 7 ( O n l i n e S i m u l a t i o n ) K sp1 = _____N/m. -6 2. Using spring’s constant you just found for the spring, determine the unknown masses of red and blue masses. M red = _________ kg, M blue = _________ kg, -4 3. Using spring’s constant you found for the first spring and a known mass, determine the acceleration due to gravity of Jupiter, Moon, and Planet X. g Jupiter = ____ m/s 2 g Moon = ____ m/s 2 g Planet X = ____ m/s 2 -6 4. Apply the above settings and answer the questions a. Remove damping (or slide to none) b. Check the stopwatch box to activate the timer c. Attach the 100g mass slowly and record the initial position of this spring-mass system. d. Now stretch additional 10cm and let it be moving up and down so that it constitute SHM 5. Record the time it takes for 20 complete oscillations and calculate the period (the time for one complete cycle). Time (t) = ______ s, Period (T) = ______ s -4 6. Using the spring constant found in step 1 and the 100g mass, calculate the period of this SHM. Hint use equation described in the Introduction. -3 7. Compare the periods you found in steps 4 and 5 -2 8. Repeat steps 4 to 7 for Jupiter. -8 Step 4: Time (t) = ______ s, Period (T) = ______ s Step 5: Period (T) = ______ s Step 7: _____________________________________________________________ 9. Using the spring constant you found in step 1 and the red and blue masses found in step 2, calculate the period of these masses. -4 T red = ______ s, T blue = ______ s, Follow-up Questions: -16 (-2 points each) 1. How far would a spring with a constant of 20 be extended with a force of 160 N?____________ 2. How much force would be required to stretch a spring (k = 12) 3.6 meters?____________ 3. As mass on a spring increases, the period of motion (one full up and down) increases /decreases / remains the same. 4. As gravity (Jupiter) on a spring increases, the period of motion increases / decreases /remains the same.
