An interactive simulation that teaches about gravitational force, circular motion, and astronomy by manipulating the sun, earth, moon, and a space station to observe the effects of gravity and orbital paths. This simulation can either be...

By the end of this section, you will be able to understand the four basic forces that underlie the processes in nature: gravitational, electromagnetic, weak nuclear, strong nuclear forces.

An interactive Java applet where users can rotate a vector about its tail and view the components of that vector. Magnitude of the components is updated on screen as the vector is dragged.

Wikipedia's site on centripetal force provides a section explaining the difference between centripetal force and centrifugal force. Includes formulas and hyperlinked terms.

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

The mathematical model for the relationships between work and energy serves to model physical problems and, more importantly, predict natural and man-made phenomena. Students discover the relationships which serve as a powerful...

In this active learning activity, students will find a technique to move a car with one hand. Students are given only a tow strap, so the students must apply angular force to successfully move the car with one hand.

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.

Through interactive examples and practice problems, this tutorial helps students understand net force-acceleration problems in which an applied force is directed at an angle to the horizontal.

A lab experiment involving readily available materials. Students analyze three forces acting upon one point to determine the resultant force. Questions and accompanying answers are provided.

Explore adding vectors by dragging objects on a canvas. Adding vectors can be easy with this Vector Guessing Game Interactive. Students can improve their understanding and skill at adding vectors using the head-to-tail method.

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.

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...

This physics tutorial provides students illustrated examples and interactive practice problems containing perpendicular components of motion.

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.

Try these vector addition challenges where twenty-five vectors are displayed on a grid. Each challenge involves adding three of the vectors together to determine the resultant. The emphasis of the activity is on component addition.

Watch this short demonstration that focuses on a single question: Does the order in which vectors are added together affect the magnitude or the direction of the resultant?

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

Try this adding vector challenge. Two random vectors are displayed, and students must quickly decide on the size and direction of the resultant. The challenge is to solve as many correctly as possible in 20 seconds. Repeat, and beat your...

In this physics tutorial on vectors, the use of kinematic equations to solve non-horizontally launched projectiles is demonstrated.

Watch this video tutorial, and find out why work is not a vector. [4:48]

Learn more about the properties of velocity, acceleration, and force vectors in this illustrated article.

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.
