Heat Transfer: Conduction, Convection, Radiation
By Laurie Jarvis, Deb Simonson
In this animated activity, learners explore three major methods of heat transfer and practice identifying each.
Newton's First Law of Motion - Video
By Kim Ristow
The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."
Newton's Third Law of Motion - Video
In this learning activity you'll examine Newton's Third Law: for every action, there is an equal but opposite reaction.
Newton's Second Law of Motion - Video
In this learning activity you'll examine force, mass, and acceleration to understand this "Law of Acceleration."
Mass Versus Weight
In this learning activity you'll explore the difference between mass and weight.
By Terry Bartelt
In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.
What Is Electricity?
The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.
Methods of Producing Electricity
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
Construction of Free-Body Diagrams
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.
Using Graphs to Explain Motion (Screencast)
By Henry Merrill
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.
What Is Torque? (Screencast)
Learners read a description of torque and study the factors that cause its magnitude to change.
