In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Introduction to Class 1 Levers
By James Bourassa, John Rosz
In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.
Quality at the Source
By Kaye Krueger
Learners read how quality can be built into a manufacturing process.
The Transistor Symbol
By Terry Bartelt
In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
Impedance: Parallel to Series Conversion
By Patrick Hoppe
Students view the formulas to be used to convert a parallel impedance to a series impedance.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
RPM of AC Motors
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
The DC Shunt Motor
Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.
In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.
Basic DC Electrical Motor Construction
Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.
Work and Power Formulas
Grade 8 Physical Science
Properties of Exponents: Multiplication Rule - Set 2
You'll practice solving problems using the rule for multiplying powers with the same base.
I am using this object as a refresher course in calculating RPM and TORQUE.
