Section outline

  • Welcome back Year 10s!

    Hope you have had a relaxing break. We will be continuing for deepening your understanding of forces and physical phenomena

    WALT- Explore Hooke's Law

    Success Criteria:

    I can explain Hooke's Law
    I can find the spring constant by applying Hooke's Law to a Spring Lab Simulation

    Activities:

    1. Copy the following notes in your book

    Hooke's Law is a law of mechanics and physics discovered by Robert Hooke. This theory of elasticity says the extension of a spring is proportional to the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit.
    Hooke's law is important because it helps us understand how a stretchy object will behave when it is stretched or compacted. The main component of car shocks are springs, and understanding how the spring will behave (using Hooke's Law) is ideal for enhancing the technology.
    Mathematically, Hooke's law states that the applied force F (N or kg·m/s2) equals a constant k (N/m or kg/s2) times the displacement or change in length x (meters), or F = kx. Sometimes Hooke's law is formulated as F = −kx.

    2. Watch the 2 videos below to gain an understanding of Hooke's Law BEFORE you do the lab simulation

    3. Do the PHET Lab guided simulation task - see GC
