The Physics Classroom: Motion and Forces in Two Dimensions: What Is a Projectile

An extensive discussion of vector addition with links to interactives and exercises.

Students examine examples of vectors that are directed in two dimensions- upward and rightward, northward and westward, eastward and southward, etc.

The emphasis of this unit is to understand some fundamentals about vectors, and to apply the fundamentals in order to understand motion and forces that occur in two dimensions.

In this unit, students learn two basic methods for determining the magnitudes of the components of a vector directed in two dimensions. The two methods of vector resolution students will examine are the parallelogram method the...

Through illustrated examples and interactive practice problems, students explore problems that involve relative velocity- where the actual motion of an object is different than its motion relative to a stationary observer.

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.

In this physics tutorial, students learn how to approach more complex vector addition situations by combining the concept of vector components and the principles of vector resolution with the use of the Pythagorean theorem.

Three complete tutorials on vectors and two dimension forces and motion. Lessons include informational text, interactive activities, animations, and quick, interactive comprehension checks along the way.

This physics tutorial illustrates problems that show the vector sum of two or more vectors is the resultant.

Learners explore vectors, projectile motion, and forces in two-dimension. The tutorial consists of lessons and problems to check for understanding.
