Hooke's law
Hooke's law: restoring force is proportional to extension, F = −kx.
Hooke's law: restoring force proportional to extension.
Key formulas
F=-kxT=2\pi\sqrt{m/k}
How to use
- Tune mass m, stiffness k, and amplitude A.
- Watch the spring stretch and the restoring force.
- Check that F scales with x in the readouts.
Applications
- Hooke's law: Hooke's law: restoring force proportional to extension.
- In class, tune parameters for “Hooke's law”, then check against the textbook result.
FAQ
Where is equilibrium?
At rest with a hanging mass, kx = mg so x = mg/k.
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Hooke's law” lab practice?
Tune parameters and match readouts to the “Hooke's law” relations — useful for prep and demos.
Is force always along velocity?
No. Net force aligns with acceleration; velocity can point elsewhere.
