Newton’s Universal Law of Gravitation – Practice Problems


  • 1. Draw free body diagrams (including annotations and calculated values) representing the following situations (consider g = 10 ms-2)

    • A 50 kg student in an elevator at rest

    • A 50 kg student in an elevator moving downwards at 2 ms-1.

    • A 50 kg student in an elevator moving upwards at 5 ms-1.

    • A 50 kg student in an elevator accelerating upwards at 1 ms-2.

    • A 50 kg student in an elevator accelerating downwards at 3 ms-2

    • A 50 kg student in an elevator falling freely
