Document Summary

Phys 101: physics for the life sciences - lecture 1: review of linear. X and vavg only depend on initial and final values i. e. they are path independent quantities. For a round trip (i. e. xf = xi) the vavg is the same as the slope of a line that connects the two points (tf,xf) and (ti,xi). V(t) = velocity at some instant of time. To get instantaneous velocity calculate vavg the for the two times close the point of interest. Xf = final position = x(tf) = x(t + t) T 0 x (t+ t) x (t) Acceleration = rate of change of velocity. A(t) = acceleration at some instant of time. Vf = final velocity = v(tf) = v(t + t) Slope of the line = rise run = lim. The slope of the position-time graph gives you the velocity-time graph.
