Hooke's Law (AKA The Big Spring), 1R10.10

Topic and Concept:

Properties Of Matter, [:PropertiesOfMatter#HookesLaw: 1R10. Hooke's Law]

Location:

Floor Item: ME, East Wall

attachment:HookesLaw-03-400.jpg

Abstract:

Add weights to a large vertical spring one kg at a time while examining the force-displacement which is marked in Newtons.

Equipment	Location	ID Number

apparatus	Floor Item: ME, East Wall

Important Setup Notes:

Setup and Procedure:

Place the device so that the audience can see the spring.
Incrementally add weight to the weight hanger and observe the displacement.

Cautions, Warnings, or Safety Concerns:

Discussion:

Hooke's law states that the restoring force exerted by a spring is proportional to the displacement from equilibrium of the spring: F = -k * Δx, where F is the force, k is the spring constant associated with specifics of the spring, and Δx is the displacement from equilibrium of the spring. This law is applicable so long as the spring is not permanently deformed in the process. The negative sign is in the equation since the spring acts to oppose displacement.

Our particular spring has a spring constant of 265.1 kg * s^-2.
