Unformatted text preview: RECTILINEAR KINEMATICS (straight line motion of particles) RECTILINEAR KINEMATICS (constant acceleration) PROJECTILE MOTION (same as Rectilinear Kinematics above, but ) Curvilinear Motion ( (Two forms of problems) Path Given (in x-y plane) y=f(x), use chain rule to find vx, ax, vy, ay (2 of these must be known in order to solve) CHAIN RULE EXAMPLE: is given as a path equation. Find the 1st and 2nd time derivatives of this equation. Parametric Equations Given: can be R (t), v (t), or a (t) n-t acceleration or and Instantaneous Center (IC) Method : v B = v B/IC v B/IC = x r B/IC RIGID BODY MOTION and FIXED AXIS ROTATION Angular motion Constant Fixed Axis Rotation motion of a POINT r v = MESHED GEARS =d/dt =d/dt Arc Lengths Velocities Tangential accelerations WORK ENERGY = +- 2 2 1 1 T U T U Force = Fcos * distance U Force = ds F S S 2 1 cos U weight = +/-mg(h 2-h 1 ) U spring = -(1/2)k ) ( 2 1 2 2 s s- U constant couple = m ( If m is not constant,...
