Concepts & Terms for  CH's  7, 8, 9

CH 7
Definitions of all angular quantities related to angular motion:
angular displacment
angular speed
angular acceleration
Compare and contrast angular speed and acceleration to the tangential speed and acceleration
Compare and contrast angular acceleration, tangential acceleration, centripetal acceleration
Definitions of centripetal acceleration and centripetal force
Know Gravity as example of a centripetal force
Newton's Law of Universal Gravitation (only qualitatively with dependence on mass and distance between masses)
Compare angular equations of motion to linear equations of motion

CH 8
Definition of Torque and lever arm
Conditions for Equilibrium (for forces and torques)
Axis of rotation (or pivot point)
Center of Gravity (or Center of Mass)
Be able to recognize the Forces and Torques that can be acting on an Object (section 8.4 examples)
Only Qualitatively note that a "net" torque produces angular acceleration, thus:
(sum)F = ma    relates to  (sum)Torque = Ia   (SEE eqn 8.8)

CH 9
Basic properties of 4 states of matter:   solid, liquid, gas, plasma
Compare and contrast the states of solid, liquid, and gas
General definition of pressure and equation for pressure with depth in a fluid
Absolute versus Gauge pressure
Pascal's principle and application to hydraulics
definition of buoyant force in a fluid
Archimedes principle and application to floating and submerged objects
Conditions for an "ideal" fluid (under fluids in motion)
Equation of continuity and conservation principles associated with it for fluids in motion (only qualitatively)
Bernoulli's equation and conservation principles associated with it for fluids in motion (only qualitatively)
