In this learning activity you'll examine force, mass, and acceleration to understand this "Law of Acceleration."

In this learning activity 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.

In this interactive object, students view an animated depiction of Class 2 levers. A matching quiz completes the activity.

Learners read a description of torque and study the factors that cause its magnitude to change.

In this interactive object, students calculate capacitive reactance, impedance, current, and power in parallel RC circuits.

In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.

Students identify the various regions of the human body through drag-and-drop exercises.

Learners read about nonverbal communication. In a drag-and-drop exercise, they evaluate photos of people interacting and determine if the behaviors shown interfere with communication or enhance it.

The learner constructs a nail and identifies the terms relating to the structures of the nail in a matching exercise.
