PHY 101 Work, Energy and Power Objective Question

Question

What is the potential energy stored in a spring compressed or stretched by a distance x?
Options
A PE_s = kx
B PE_s = -kx
C PE_s = ½kx²
Correct Answer
D PE_s = -½kx²
Correct Answer

Option C is the correct answer.

Detailed Explanation

The elastic potential energy stored in a spring is given by PE_s = ½kx², where k is the spring constant and x is the displacement from its equilibrium position.

Hint

It's the energy stored due to the spring's deformation.
