Lab 14. Potential Energy Diagrams and Potential Wells

PART 1. Potential Energy Diagram

1. 
Answer : Range of motion will be between -5 and 5 cm 

2. 
Answer : The particle can not travel more than 5 cm from the origin because the particle doesn’t have enough energy to surpass the potential barrier.

3. 
Answer : Probability of detection is higher between -5 and 0 because the particle spends more time there (less kinetic energy).


4. 
Answer : E=1/2kx^x, 2E>sqrt2x

5 & 6. 
Answer 5: Kinetic energy vs. potential is an upside down parabola with vertex at x=0.
Answer 6: Most detected at extrema since kinetic energy is minimum.


PART 2. Potential Wells

1. 
Answer :
