1C10.20 – Driven and coupled carts on rails
This demonstration illustrates the influence of the spring constant, amplitude of the oscillation, and the mass of the cart on the period of oscillation of the one/two cart system.
Hooke’s law
1R10.10 – Hooke’s Law
This demonstration shows Hooke’s law, in this case for the extension of a spring. Knowing that the force applied to the spring is directly proportional to the extension caused by that force, we can find a value for the constant of proportionality that relates these quantities.
