Measuring SHM

The period of a pendulum may be decreased by

• Increasing the mass of the bob
• moving the equilibrium point
• decreasing the mass of the bob
• shortening the length of pendulum

The angle between the string of a pendulum at its equilibrium position and at its maximum displacement is the pendulum’s

• period.
• frequency.
• vibration.
• amplitude.

If an object completes a full cycle of oscillation, which of the following statements must be true

• The object returned to its starting position

• The object returned to its starting position and is facing the same direction as when it started moving

• The object is moving in the same direction as when it started

• The length is equal to the period

Two mass spring systems are vibrating up and down. Spring A has spring constant that is much larger than Spring B. Which spring will have a larger period

• Spring B

• Spring A

• They will have the same period

• They will not have a period

Describe the relationship between amplitude and period for a mass-spring system and a pendulum that are in SHM

• As amplitude increases period increases

• As amplitude increases period decreases

• As amplitude increases period remains the same

• As amplitude increases, the period remains the same for the pendulum and increases for the mass spring system

Two pendulums with the same length are swinging. Pendulum A has twice the mass of pendulum B. Which pendulum will have a larger period?

• Pendulum A

• Pendulum B

• They have the same period

• They will not a have a period

When is a pendulum in simple harmonic motion?

• Never

• All the time

• only at large angles

• only at small angles

When is the pendulum at maximum velocity

• At its lowest point

• At its highest point

• It moves at a constant velocity

• It is at rest

When the mass reaches point x = 0 its resorting force?

• Maximum and positive

• Maximum and negative

• Zero

• Less than maximum and negative
