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."
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."
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.
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.
Mass Versus Weight
In this learning activity you'll explore the difference between mass and weight.
