Great! Now let's review the most important ideas you'll want to remember.
Essential Idea
Take one last look at the most important concept from this topic. If you remember this idea, the rest will come back much more easily.
ESSENTIAL IDEA
Force, Energy, and One Conservation Equation
Use Hooke’s law for force, ½kx² for stored energy, and conservation of mechanical energy between carefully chosen states.
Fs = −kx; Us = ½kx²; Ki + Ui = Kf + Uf. Example: at maximum deformation v = 0; at equilibrium x = 0.

CONFIDENCE CHECK
Five-Minute Readiness Check
Answer without notes, then reveal the explanation.
A spring is compressed twice as far as before. By what factor does its stored elastic potential energy change?
Reveal Answers
It becomes four times larger.
Why it works: Us is proportional to x².
