AP PHYSICS 1 UNIT 6 PROGRESS CHECK: ANSWERED ACCURATELY

What is the magnitude of the change in potential energy of the block-spring system when it travels from its lowest vertical position to its highest vertical position? 1/2k0(L1+L2)^2 The students conduct experiment 2 in which the same block is connected to the same spring on a horizontal surface. The spring is stretched a distance L2 beyond its natural length and released from rest, allowing the block-spring system to oscillate. Frictional forces are considered to be negligible. Which of the following claims is correct about how the period of oscillation for the block-spring system in experiment 2 compares with the period of oscillation for the system in experiment 1, and what evidence supports the claim? The periods of oscillation for experiment 2 and experiment 1 are the same, because the block and the spring used in both experiments are identical.
