RIII-1 Phys2010 Exam 3 Review: Chapter 6: Work and Energy F WFd= ? & net WKE , work can be (+), (?), or zero . work done by force F: = ?. work-energy principle: . If no thermal energy generated, E mech = KE + PE = constant . If thermal energy generated, KE + PE + E thermal = constant . Hooke's Law: F spring = ? k x (k = spring constant) . PE grav = m g h PE elastic = (1/2) k x 2 W P t ? = ? 2 2 m v constant= G net pF t?= ?? G G . Power Chapter 7: Momentum . Conservation of momentum: for system isolated from outside forces, 11tot p m v=+ GG . Impulse = . elastic vs. inelastic collisions. KE is conserved only in perfectly elastic collisions. Chapter 8: Rotations Notice analogy between rotation about a fixed axis and 1D translation along the x-axis: . s (rads) = , rt , ?? ?=? = t ?? ? ?? ( like xv x v = , a = tt , ? ? ? ? ) . v = r ? , a tan = r ? rF ...
