- Not completed: Mass and Weight
These topics can make this lesson easier, but you can start now.
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
