1.

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?
