Variation on the standard Atwood's Machine model, where one hanging mass swings like a pendulum and the other remains stationary. Manipulate the conditions and observe the results.

[Free Registration/Login Required] Learn about orbits and how an object can stay in orbit under the influence of gravity. By adjusting launch velocities users will understand how to successfully put a virtual satellite into orbit without...

This University of Minnesota site provides a series of contextually rich, real-world problems demonstrating force and Newton's second law of motion.

Use this outline to find out about Newton's Laws of Motion. Use the different lesson plans covering the laws of motion to learn more.

Looks at how Newton's three laws of motion apply to an analysis of the forces being exerted when playing football.

This instructional activity is for 9th grade physical science students. It begins with an inquiry-based instructional activity using a projectile motion computer simulation. It culminates with students building a catapult; applying and...

While most people know what Newton's laws say, many people do not know what they mean. This tutorial allows students the ability to understand their meaning and to believe their implications.

The interactive simulation demonstrates the conservation of momentum through a Newton?s Cradle simulation.

[Free Registration/Login may be required to access all resource tools.] The following tutorial helps students to understand how to apply Newton's Second Law under equilibrium conditions in two dimensions.

This site from NASA provides a graphic depicting Newton's second law. Graphic is accompanied by an explanation. Part of a larger site with additional information on Newton's laws.

[Free Registration/Login Required] Learn about centripetal motion in the context of a bobsled on a track. Adjust variables to test how many ways the bobsled can stay on the track in a race with the simulation. Examine potential problems...

[Free Registration/Login may be required to access all resource tools.] How to calculate acceleration from force and mass, and force from mass and acceleration.

Have you ever felt that queasy feeling in a moving elevator? Explore the physics behind the sensations of weightlessness and weightiness. Teacher notes and a downloadable handout are also provided.

NBC Learn, in partnership with the United States Golf Association, uncovers the science, technology, engineering and math behind the game of golf. For lesson plans provided by the National Science Teachers Association, open the video and...

This site by the Illinois Institute of Technology gives a Lab activity in which pupils use a variety of toys to discover Newton's second law and momentum conservation. Newton's cradle, skate boards, and a toy motorcycle are incoporated...

This lecture covers Newton's three laws of motion. You can watch the lecture on video or listen to audio. A transcript of the lecture and practice problems are also provided.

Presents labeled illustrations modeling each of Newton's three laws of motion along with explanations.

Background information on vectors and their use in describing motion in two dimensions. A comparison of Aristotle's and Galileo's perspectives on force and motion is given.

This University of Minnesota site provides a series of contextually rich problems pertaining to force, Newton's second law of motion, and linear kinematics.

Students explore the motion of an object falling under the influence of air resistance. Force arrows and values are shown as the object falls, and a speedometer displays the speed of the object. The mass of the falling object and the...

Through illustrated examples and practice problems, students explore the centripetal force requirement. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration.

Through illustrated examples and interactive practice problems, students find the value of forces acting upon objects using force equations.

This lab was designed to have students investigate the factors that affect the acceleration of an object on a frictionless horizontal surface. The simulation will give the students a position vs. time graph and a velocity vs. time graph....

This lab was designed to have students investigate the factors that affect the acceleration of an object on a frictionless horizontal surface. The simulation will give the students data from two photogates which they must use to find the...
