CHAPTER 4 TEST OUTLINE FORCES:  Describe forces  Types of forces  Balanced vs. unbalanced forces  Forces worksheet  Forces on a rocket (drag, lift, thrust, weight) NEWTON’S 3 LAWS OF MOTION:  Know all three laws

SECTION 4.1 FLUID FLOW  Describe fluids and matter  Types of systems (dynamic vs. static)  Types of dynamic systems (aerodynamics vs. hydrodynamics)  Explain the KMT  Compare and contrast solids, liquids and gases by shape, volume, motion, spacing, energy, force of attraction (see table in notes)  Know melting, evaporation, condensation, solidification, and sublimation

SECTION 4.2 FLUID FLOW AROUND OBJECTS (ROCKET)  Difference between laminar and turbulent flow  Examples of laminar vs. turbulent flow  What you want your rocket to demonstrate

SECTION 4.5 MEASURING MATTER  Difference between mass and weight

SECTION 4.7 DENSITY  Describe density (definition, units)  Calculate volume using math or displacement  Solve density problems  Use density to determine if something sinks or floats  Read a density table

SECTION 4.12 HOW TEMP. AFFECTS VISCOCITY/DENSITY/BUOYANCY   T   E   Speed   Spacing (V)   D   Force of attraction   Viscosity (thickness)   Buoyancy **REMEMBER : the reverse as well!  Why water is a “special” case
