## Physlet® Physics Two-Dimensional Kinematics Problems

In PhysletÂ® Physics Two-Dimensional Kinematics Problems we generalize the study of motion in
one dimension to the motion of objects in two dimensions. In doing so we discuss two of the
most important forms of two-dimensional motion, projectile motion and circular motion.
motion.

The problems in this section are interactive versions of the kind of exercises typically
assigned for homework and are based on the Two-Dimensional Kinematics Illustrations to test
your knowledge of these ideas.

## EjsS Physlets

EjsS PhysletsPhyslet® are JavaScript adaptations of PhysletPhyslet® curricular
material developed using version 5 of the Easy Java/JavaScript
Simulations (EjsS) authoring and modeling tool. The illustrations and problems in these
packages are adapted from the Java applet version of Physlet Physics by Wolfgang Christian and Mario
Belloni and are available on the Open Source
Physics website. The simulations in these package are implemented in JavaScript so that
they can run on both desktop computers and mobile devices.

PhysletPhyslet® **Illustrations** are designed to demonstrate physical
concepts. Students need to interact with the Physlet, but the answers to the questions posed
in the Illustration are given or are easily determined from interacting with it. Many
Illustrations provide examples of physics applications. Other Illustrations are designed to
introduce a particular concept or analytical tool. Typical uses of Illustrations would include
"reading" assignments prior to class and classroom demonstrations.

PhysletPhyslet® **Problems** are interactive versions of the kind of exercises
typically assigned for homework. They require the students to demonstrate their understanding
without as much guidance as is given in the Explorations. They vary widely in difficulty, from
exercises appropriate for high school physics students to exercises appropriate for
calculus-based university physics students. Some Problems ask conceptual questions, while
others require detailed calculations. Typical uses for the Problems would be for homework
assignments, in-class concept questions, and group problem-solving sessions.

Additional EjsS models can be found by searching for the expression "JS Models" on the Open Source Physics website.

PhysletsPhyslet® were
developed at Davidson College by Wolfgang
Christian.
