Newton's Second Law of Motion - Video

By Kim Ristow

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

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.

What Is Torque? (Screencast)

By Terry Bartelt

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

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.

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.

Thermodynamic Transfer

In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.

Slope and Intercept on Graphing Calculators

By Ron Keys

The learner reads directions for finding the slope, intercept, and correlation coefficient for a group of ordered pairs using one of eight different scientific calculators.

Introduction to Class 3 Levers

By James Bourassa, John Rosz

In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

Introduction to Class 1 Levers

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.

Statics - Trig: Law of Cosines

By Steve Whitmoyer

In this interactive object, learners use the Law of Cosines to calculate forces.

What Is Torque?

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

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 First Law of Motion - Video

The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."

Mass Versus Weight

In this learning activity you'll explore the difference between mass and weight.

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

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.
