Wolfs Department of Physics and Astronomy, University of Rochester Physics 121 Updated course information The Physics 121 workshops will start on Monday January 28. The physics 121 laboratories will start also on Monday January 28. There will be no lecture on Thursday 1/31. I will be in Europe from Wednesday 1/30 until Monday 2/4. Anyone who did not take the Diagnostic Test on Tuesday 1/22 needs to make up this test on Thursday morning 1/31 at 9.40 am in Hoyt (it will take 45 minutes to complete this Diagnostic Test).

2 Frank L. H. Wolfs Department of Physics and Astronomy, University of Rochester Review of motion in one dimension. Translational motion on one dimension can be described in terms of three parameters: The position x ( t ): units m. The velocity v ( t ): units m/s. The acceleration a ( t ): units m/s 2 . An important special case is the case of constant acceleration (acceleration independent of time) a = dv dt = constant v(t) = v 0 + a t x(t) = x 0 + v 0 t + 1 2 a t 2 Frank L. H. Wolfs Department of Physics and Astronomy, University of Rochester Review of motion in one dimension. a = dv dt = - g v(t) = v 0 - g t y(t) = y 0 + v 0 t - 1 2 g t 2 Note: in this format, g is assumed to be the magnitude of the gravitational acceleration.
