FoundationWhat is the relationship between frequency f and period T for periodic motion?
Need a small nudge?

Frequency counts cycles per second, while period measures seconds per cycle.

UnderstandingFor ideal one-dimensional simple harmonic motion, which statement is correct?
Need a small nudge?

Compare the direction of the restoring force with the displacement from equilibrium.

ApplicationAn oscillator completes 2.0 cycles each second. What is its period?
Need a small nudge?

Convert cycles per second to seconds per cycle by taking the reciprocal.

InterpretationFor an ideal mass-spring oscillator, the mass is increased by a factor of 4 while the spring constant is unchanged. How does the period change?
Need a small nudge?

Use the mass-spring period relation and examine how the square root responds to a factor of four.

ConnectionA 200 N/m spring oscillates without friction with amplitude 0.10 m. When its displacement from equilibrium is 0.060 m, what are the spring potential energy and the kinetic energy of the oscillator?
Need a small nudge?

Find the total spring-oscillator energy from amplitude, then subtract the spring potential energy at the stated displacement.
