  1. Question 1

    Q1. A spring of spring constant 50 N/m is compressed by 0.4 m. What is the potential energy stored?

    • A) 4 J
    • B) 8 J
    • C) 2 J
    • D) 1 J

    Answer: 4 J

    Explanation: Potential energy = 1/2 kx² = 1/2 * 50 * 0.4² = 4 J, using the formula for spring potential energy.
