As
the mass moves up and down, what energies are involved? How did
the mass get the original amount of each kind of energy?
|
|
| 2.
|
What relationship gives the amount of elastic energy in the spring?
|
| 3. |
How can you tell that this is a Simple Harmonic Motion?
|
| 4. |
Compare the amounts of each kind of energy (in a qualitative way)
at the three extremes of motion - highest, middle and lowest
point.
|
| 5. |
Construct a spreadsheet that contains the values of the following
quantities:
 Constants:
Mass, Spring Constant |
|
Variables: |
| |
Position (height), Velocity, Time |
|
Calculated Values: |
|
Gravitational
Potential Energy (Ug) |
|
Kinetic
Energy (K) |
|
Elastic
Potential Energy (Ue) |
|
Total
Mechanical Energy (Et) |
|
| 6. |
Record the position, velocity and time for at least 15 different
positions during a single cycle of the motion.
|
| 7. |
Calculate
Ug based on height above the lowest point of the motion.
|
| 8. |
Calculate
Ue based on distance below the highest point of the motion.
|
| 9. |
Graph all four calculated values as functions of time.
|
| 10. |
What is your conclusion regarding the total mechanical energy during
a cycle of motion?
