5

TRUE OR FALSEThe period of motion for a pendulum is dependent on the mass of the pendulum bob.


6

TRUE OR FALSEThe period of motion for a pendulum is dependent on length of the pendulum.


How long must a pendulum be to have a period of 1.27 seconds on earth?

7


8

TRUE OR FALSEThe period of motion for a block hanging from a spring is dependent on acceleration due to gravity.


9

A 50 g mass hangs from a spring and begins to oscillate. What is the spring constant of a spring if it oscillates 5 times per second?


10

A 50 g mass hangs from a spring. The mass is pulled downward a distance of 10cm and released. How far does the mass travel after 3 cycles?


A disturbance that is caused by a vibrating source and transfers energy is known as:

________________ motion.
