# 4.7: Unit 4 Review

### Key Terms and Concepts

Mass

Volume

Density

Weight

Apparent Weight

Static Equilibrium

Net Force

Buoyant Force

Archimedes' Principle

Hydrostatic Weighing

Specific Gravity

### Learner Outcomes

1. Define mass, volume, density, weight and apparent weight.[1]
2. Explain how mass and weight are related when near the surface of Earth and calculate one from the other.[1,2]
3. Apply the concept of static equilibrium to determine the magnitude and direction of unknown forces.[3]
4. Apply Archimedes’ principle to determine the buoyant force objects and decide if they will sink or float.[2]
5. Determine density from mass and volume measurements and via hydrostatic weighing.[4]
