A force of  30 N stretches a very light ideal spring 0.73 m from equilibrium. What is the force constant (spring constant) of the spring?

• 41 N/m

• 22 N/m

• 34 N/m

• 46 N/m

If the length of a simple pendulum is doubled, its period will: 

• halve 

• increase by a factor of sqrt(2) 

• decrease by a factor of sqrt(2)

• double 

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

A pendulum oscillates as shown. At which of the following positions is the potential energy equal to the total energy?

• A

• B

• C

• Not enough information

Match the following

• driven oscillator

• result of a driven oscillator that causes the object to vibrate greater

• resonance

• keeps the oscillations going

• damped oscillator

• force that acts against the motion of an oscillation to stop it

• friction

• acts against the motion of the oscillations using friction this then transfers the energy out of the system
