An interactive simulation that teaches about motion, acceleration, and velocity by allowing students to build their own solar system and watch the effects of gravitational pull and how that changes with initial position, velocity, and mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional materials.

Explore forces and motion as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces.

Learn about position, velocity, and acceleration graphs. Move the little man back and forth with the mouse and plot his motion, and then set the position, velocity, or acceleration and let the simulation move the man for you.

Enhance study of motion, velocity, acceleration, position and graphing with this interactive simulation.

A GIF animation comparing the motion of three cars. A graphical depiction is given. Includes three thoughtful questions with answers in a pop-up menu.

This resource provides a detailed explanation of a resultant, in terms of vectors. Content also includes helpful examples.

Learn about the relationship between velocity and position for a swimmer. Adjust the velocity of the legs, streamline, and arms to experiment with the slope of velocity in the simulation swimmer. Dig a bit deeper into the physics of swimming with additional examples.

Learn about the relationship between position and velocity for a diver accelerating under the influence of gravity and air resistance. Measure velocity and position based on variables of the height of the cliff and air resistance. What did Galileo's free-fall mean? Find out from one of the four additional examples highlighting acceleration due to gravity.

Students explore the physics utilized by engineers in designing today's roller coasters, including potential and kinetic energy, friction, and gravity. First, students learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they also consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars as they travel around the track. During the associated activity, the students design, build, and analyze a roller coaster for marbles out of foam tubing.

Students are introduced to the physics concepts of air resistance and launch angle as they apply to catapults. This includes the basic concepts of position, velocity and acceleration and their relationships to one another. They use algebra to solve for one variable given two variables.

This animated physics video explains what centripetal force is and how it relates to Newton's second law of motion. [1:46]

Video tutorial investigates how to plot projectile displacement, acceleration, and velocity as a function to change in time. [16:17]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

Students observe four different classroom setups with objects in motion (using toy cars, a ball on an incline, and a dynamics cart). At the first observation of each scenario, students sketch predicted position vs. time and velocity vs. time graphs. Then the classroom scenarios are conducted again with a motion detector and accompanying tools to produce position vs. time and velocity vs. time graphs for each scenario. Students compare their predictions with the graphs generated by technology and discuss their findings. This lesson requires assorted classroom supplies, as well as motion detector technology.

A narrated presentation illustrates some problems calculating the acceleration of an object when time is unknown, but position and velocity are. [6:45]

Principles of Macroeconomics 2e covers the scope and sequence of most introductory economics courses. The text includes many current examples, which are handled in a politically equitable way. The outcome is a balanced approach to the theory and application of economics concepts. The second edition has been thoroughly revised to increase clarity, update data and current event impacts, and incorporate the feedback from many reviewers and adopters. Changes made in Principles of Macroeconomics 2e are described in the preface and the transition guide to help instructors transition to the second edition. The first edition of Principles of Macroeconomics by OpenStax is available in web view here.
