In this screencast, you'll observe two vehicles moving across the screen at different rates then describe the motion. Additionally, you'll select the corresponding graphs of distance vs. time, velocity vs. time, and acceleration vs. time for each vehicle.
This screencast, we see how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.
In this screencast, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.
In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.
In this screencast, students demonstrate an understanding of summary writing by reading step-by-step instructions and then summarizing short paragraphs. Examples of summaries that are poorly written, as well as those that are written well, are included.
