What is the natural frequency of an object?

• The frequency at which it oscillates with maximum damping

• The frequency at which it oscillates with damping

How do you calculate the total spring constant for springs in series?

• K total = K1 x K2

• K total = 1/(1/K1 + 1/K2)

• K total = K1 + K2

• K total = K1 - K2

In a parallel spring configuration, how is the total spring constant calculated?

• K total = K1 + K2

• K total = 1/(1/K1 + 1/K2)

• K total = K1 x K2

• K total = K1 - K2
