Document Summary

Distance vs displacement: average (speed/acceleration) vs instantaneous. Graphical relationship between disp. , vel. , and acceleration. Special case of motion at constant acceleration (eg. freefall): v = v0 + at. 1. an object moving in one dimension has negative velocity and positive acceleration Chapter 3: 2-d kinematics & vectors: vector components/frames of reference, projectile motion: constant acceleration, projectile motion as parabolic x = vx0 t y = vy0 t gt2 dproj = . 1. fbds are for one object (at a time) 2. draw all forces on that object (direction): 3. setup fnet = ma in two (independent) directions. 4. if there are multiple objects: a) repeat 1-3 above for each object. B) use newton"s third law to help resolve forces. 2. in the loma prieta (california) earthquake in 1989, horizontal ground accelerations of up to. 5. in the diagram, two blocks are connected by a massless string. the table is frictionless.
