Buoyancy and Archimedes' Principle

Difficulty 5/10 ~12 min

🎯 Learning Objectives

  • Students will understand Archimedes' principle and buoyant force
  • Students will calculate whether objects float or sink
  • Students will apply buoyancy to real-world situations

🧠 Core Concepts

  • Buoyant force: upward force from displaced fluid
  • Archimedes' principle: F_b = ρ_fluid × V_displaced × g
  • Objects float when buoyant force equals weight
