In this interactive module, students use free-body diagrams, Newton's second law equation, and circular motion concepts to analyze a variety of physical situations involving the motion of objects in circles or along curved paths.

University site explaining what is meant by concurrent forces. The site has a free-body diagram with 3 forces acting on an arbitrary body. The site explains the conditions necessary for concurrency.

Students combine their understanding of acceleration and the fact that a net force causes an acceleration to determine whether or not a net force exists in several practice situations. After each problem, they are able to check their...

Students measure and analyze forces that act on vehicles pulling heavy objects while moving at a constant speed on a frictional surface. They study how the cars interact with their environments through forces, and discover which...

In this unit, students explore a variety of phenomena to figure out, "Why do things sometimes get damaged when they hit each other?" Student questions about the factors that result in a shattered cell phone screen lead them to...

This is a glossary of terms and definitions used in Chapter 4: Force and Newton's Laws of Motion from the AP Physics online text.

By the end of this section, you will be able to define net force, external force, and system; understand Newton's second law of motion; and apply Newton's second law to determine the weight of an object.

By the end of this section, you will be able to understand Newton's third law of motion and apply Newton's third law to define systems and solve problems of motion.

In this physics tutorial, the task of summing vectors will be extended to cases in which the vectors are directed in directions other than purely vertical and horizontal.
