3.5 Summary: Period M. Which factors does the period of a mass on a spring depend on? In what way? N. Which factors does the period of a mass on a spring NOT depend on? 0. Is this consistent with the following formula for the period of an object on a spring? Why or why not? Formula for period of an object on a spring: T = 21: V(m/k) Forces: Object on a Spring We will now examine the magnitude and direction of the forces for vertical and horizontal systems of objects on springs. Click on the Vectors section of the simulation. Hang a 100 g mass on one of the springs. Check the Mass Equilibrium box and the Forces button. Under it, check Gravity and Spring. A. Sketch a free-body diagram when the mass is hanging in the equilibrium position. Label your diagram. How does the magnitude of the spring force compare to gravity in this position? B. Pull the mass away 'om equilibrium and let go. When the mass is in an extended position, click pause. Sketch a 'ee-body diagram for the mass in this position. Label your diagram. How does the magnitude of the spring force compare to gravity in this position
