In this learning activity you'll explore a step-by-step process to solve simple free-body diagrams. They identify forces acting in the x or y direction in interactive exercises.

In this interactive object, learners examine the locations of major body cavities and their protective membranes. A drag-and-drop exercise completes the activity.

Using 10 views of the male and female body, learners match Mandarin Chinese words to the body parts they identify. After the part has been correctly named, learners click on the Mandarin Chinese term to hear it pronounced. This activity is particularly helpful for health care professionals.

In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.

Learners examine how metal detectors function. This object includes animation and sound.

Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.

Learners read about the vector diagram for a parallel RC circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.
