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

In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

In this learning activity you'll examine Newton's Third Law: for every action, there is an equal but opposite reaction.

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.

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

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.

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

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.

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

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

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.

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

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

In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.

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