Questions

  1. 1.

    In an investigation into the motion of a simple pendulum, a student keeps the bob mass and release angle constant while varying the length of the string. The student records an oscillation period of 1.0 s for a length of 0.25 m, 2.0 s for a length of 1.00 m, and 4.0 s for a length of 4.00 m. Based on the recorded measurements, which conclusion correctly interprets the relationship between the string length and the period of oscillation?

    • A) The period is directly proportional to the string length because the period increases whenever the length increases.
    • B) The period is inversely proportional to the square root of the string length because the rate of increase diminishes at longer lengths.
    • C) The period is directly proportional to the square root of the string length because quadrupling the length doubles the period.
    • D) The period exhibits a linear relationship with string length because equal changes in length cause constant additions to the period.
