  • Hooke's Law with Weights
    Hooke's Law Apparatus with weights (10 x 100 gram).

    Hooke's Law states that the stretch of a body is directly proportional to its load. This precise apparatus is the perfect way to demonstrate this concept. It can also be used to show harmonic motion. Includes: 15 cm long adjustable, reflective scale, graduated in millimeters; spring with low spring rate; weight holder with plan and pointer; illustrated instructions; slotted weights in reusable case.
