Unit 2 · 2.8 — Spring Forces

Everything to learn here

• Concept: Ideal springs exert a restoring force that is directly proportional to their displacement from their natural equilibrium length (Hooke's Law).
• Concept: The restoring force always acts in the opposite direction of the displacement.
• Equation: $$Fs=-k\cdot \Delta x\text{(Hooke’s Law)}$$
• Vocabulary: Spring Constant (k) — A scalar measurement of a spring's stiffness, measured in Newtons per meter (N/m).
• Skill: Data Analysis — Plotting experimental Force vs. Displacement data and calculating the line of best fit's slope to determine the spring constant.
