Lists for Test 1 (updated 3/3/04) Terms: Mass m Force, net force (vector sum) Momentum: linear and angular Velocity v (vs. volume V) Speed |v| Energy Kinetic energy Acceleration a Support force (normal force) Potential energy (gravitational) Work: force times distance acted through Conserved quantity Mechanical advantage: ratio of output force to input force Angular velocity ω, acceleration α Torque Right-hand rule Center of mass Moment of inertia Friction: static [no work] vs. sliding Power (work per time) Impulse Spring scale Spring constant Equilibrium Coefficient of restitution: ratio of speed of separation to speed of approach Inertial frame of reference Uniform circular motion (UCM) Centripetal acceleration “Centrifugal force” [fictitious] Pressure Buoyant force, Archimedes’s principle Ideal gas Incompressible fluid Steady-state flow Bernoulli New units and constants: Gram, kilogram Meter Newton Gravitational acceleration g Joule Watt Radian Newton-meter Pascal Absolute temperature (Kelvin): °C + 273 Boltzmann constant kB Laws: (cf. Important Laws & Equations) Kinematics: x(t) = x(0) + v(0) t + ½ a(0) t2 Momentum: m times v Kinetic energy = ½ m times |v|2 Newton’s 1,2,3: F = ma, “action-reaction” Weight = m times g [“downward”] Conservation of linear, angular momentum (pp. 69 – 70) Elastic collision: conserv’n of kinetic energy Rotational analogues, torque = moment arm × force moment of inertia: mass times (distance from axis)2 Hooke’s law: force = – k times displacement Centripetal acceleration: v2/R for UCM For UCM generally, speed = ω × r Archimedes: buoyant force is weight of dis- placed fluid (or gas), in opposite direction Ideal gas: p = (N/V) kB T Bernoulli: (Energy = PPE + KE + GPE) all over vol. Energy/V = pressure + + ½ (m/V) |v|2 + (m/V) times g times height Boldface: vector Italic: scalar
