Question

1. The plot below is called a phase plot.
Velocity, Kinetic, Potential, and Total Energies are all plotted against the position.
You can see that the position (horizontal axis) ranges from about 0.240[m] to 0.275[m].
What are the Kinetic, Potential, and Total Energies at the equilibrium position?

A. Kinetic is appox. the same as any other position; Potential is Minimum; Total is Maximum.

B. Kinetic is Maximum; Potential is Minimum; Total is approx. the same as any other position for that cycle.

C. Kinetic is Minimum; Potential is Minimum; Total is approx. the same as any other position in that cycle.

D. Kinetic is Minimum; Potential is Maximum; Total is approx. the same as any other position for that cycle.

E. Kinetic is Maximum; Potentail is Maximum; Total is twice the maximum of either Kinetic or Potential.

2. For the picture above (Phase Plot) what is approximately the equilibrium position for this mass/spring system?

A. 24.0[cm]

B. 27.5[cm]

C. 24.0[cm] AND 27.5[cm]

D. 25.8[cm]

C. Equilibrium Position isn't on this plot.

The plot below is called a phase plot. Velocity, Kinetic, Potential, and Total Energies are all plotted against the position. You can see that the position (horizontal axis) ranges from about 0.240[m] to 0.275[m]. What are the Kinetic, Potential, and Total Energies at the equilibrium position?

Explanation / Answer

Kinetic is Maximum; Potential is Minimum; Total is approx. the same as any other position for that cycle.

25.8[cm]
