Worksheet 4
... In “One-D Motion” we get quantitative about forces and accelerations for the first time. We will limit our attention to forces and motions in one dimension only. You will apply a force of adjustable magnitude to a body of adjustable mass. You will examine graphs of the position, velocity, and accele ...
