The Physics Classroom: Motion and Forces in Two Dimensions: Vectors/direction

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.

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...

Students apply both kinematic principles and Newton's laws of motion to understand and explain the motion of objects moving in two dimensions, more specifically, the motion of projectiles.

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.

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 interactive module, students will observe that motion in two dimensions consists of horizontal and vertical components. They will understand the independence of horizontal and vertical vectors in two-dimensional motion.

In this tutorial, examine the effect of forces acting at angles to the horizontal, such that the force has an influence in two dimensions- horizontally and vertically.
