Question 1
What is the formula for calculating elastic potential energy?
- E_e = kx
- E_e = 1/2 kx^2
- E_e = kx^2
💡 Hint: Remember that there's a half in the formula.
Question 2
True or False: A stiffer spring (higher spring constant) will store less elastic potential energy when compressed the same distance.
- True
- False
💡 Hint: Think about the relationship between spring stiffness and energy.

Challenge Problems
Push your limits with challenges.
Question 1
A spring is compressed by 0.5 m with a spring constant of 300 N/m. Calculate the maximum energy stored in the spring once it is released, then determine the work done when returning to the natural length.
💡 Hint: Use the potential energy formula to find the energy stored first.
Question 2
Two springs are used in an experiment. Spring A has a spring constant of 100 N/m and is stretched to 0.2 m, while Spring B has a spring constant of 200 N/m but is compressed by 0.1 m. Which spring stores more potential energy?
💡 Hint: Compare the energy stored using E_e = 1/2 kx^2 for both springs.
