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.
Learners examine how fluid enters the inlet of a hydraulic pump because of atmospheric pressure and how pressure is created at the pump’s outlet. This object includes audio.
In this interactive object, learners follow the litigation process from the filing of a court case through the filing of an appeal. Learners’ choices will move the case in different directions, based on the actions of the parties and the Court. A quiz completes the activity.
In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.
Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.
In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.
