Brick Forces
The Forces applet is designed to give the user an opportunity to develop intuition and
computational skills related to the classic problem of the motion of a brick on a frictional inclined plane. If
you can understand this problem you are well on your way to mastering much of what follows in your
course.

Ladder
The Ladder applet is designed for users to examine the conditions necessary for static
equilibrium of an object, in this case a ladder leaning against a building. Play with the coefficient of static
friction and the initial angle to see the impact on torque and force. Be careful to avoid injury from a nasty
ladder accident.

Projectile Motion
The Projectile Motion applet includes 2 different games for users to play in an effort to develop an
understanding of how objects move when projected through the air. See how promising a career as a
motocross rider, stunt person, or bow-hunter might be for you.

Circular Motion - Balls on Strings
The Circular Motion applet is designed for users to examine the basic ideas of kinematics and
forces for objects whose motion is circular. Examine the impact of mass and velocity on force and
acceleration both graphically and numerically.

Frictional Forces and Circular Motion
The Banked Curve applet is designed to simulate a racecar traveling around a track in order to
study inertia, centripetal force, and the impact of such variables as the incline of the track, velocity of the
car, and friction. Users can manipulate all of these variables in order to better understand their
relationships. Have fun trying different combinations and seeing if you can avoid a fiery crash.

Potential Energy, Kinetic Energy and Frictional Energy Dissipation: Roller Coaster
The Roller Coaster applet is designed to give users an entertaining way of examining the
principle of Conservation of Energy. Build your roller coaster, let it go, and watch the interplay between
potential and kinetic energy. See if you have what it takes to build a thrill ride for the ages.

Conservation of Momentum in 1 and 2 Dimensions: The Virtual Pool Table
The Pool Table applet is designed for users to their intuition regarding the principle of
Conservation of Linear Momentum. Use the presets or place balls of mass and initial velocity of your
choosing on the table to investigate this principle. The before and after display will give you a visual of
how the forces change during a collision. Put your newfound knowledge of the game to practical use
against your friends.

Conservation of Angular Momentum
The Conservation of Angular Momentum applet is designed for users to explore this concept and
the role radius and velocity play. Try different velocities and change the radius on the fly to see the impact
on angular momentum but be careful not to make the snowman sick.

Fluids/Buoyancy
The Fluids applet is designed for users to study the concept of buoyancy. Choose the mass of
your container and the medium it is floating in. Then load cargo to examine how the density of the
medium, the attributes of the container, and the mass of the cargo impact the ability of the container to
remain afloat. See how much cargo you can keep afloat.

Waves in 1- and 2-D: Virtual Wave Tank
The Wave Tank applet is designed to help users gain an understanding of the Principle of
Superposition of waves. Use dippers to create waves of different frequencies and locations and examine
the resulting interference pattern. Go ahead and make waves. You can learn by doing so.

The Law of Thermodynamics and Heat Engines
The Thermodynamics applet is designed to study the relationships between volume, pressure,
and temperature in a gas-filled cylinder and piston system. Through your selection of different conditions,
you can study four thermodynamic processes.

Electric Fields and the Force on a Charge
The Electric Fields applet is designed to help users gain a conceptual understanding of how
electric charges create electric fields and electric potentials. Add different charges, control the wall
effects, and what information you see or select a preset configuration to understand specific phenomena
of electric fields.

Virtual Circuits Lab
The Circuit applet is designed to simulate a real-world circuit board. Users can manipulate wires,
batteries, switches, inhibitors, and several other circuit board items to demonstrate real world principles.
Volt and amp meters are provided to give diagnostic information on the circuits you create. Experiment,
explore, and enjoy this unique and powerful online tool.

Magnetic Fields and the Force on a Charge
The Magnetic Field applet is designed to allow users to examine the effects of a magnetic field on
a charged particle. Change the particle attributes and strength of the field to see how the magnetic field
impacts the charged particle. Once the particle is fired, you can continue to change the mass and charge
to further examine how these variables change the effects.

Induction, Electromagnetic Fields and Generators
The Induction applet is designed to allow the user to explore the phenomenon of induction. Select
a type of magnetic field and experiment with the loop controls and position of the magnet to see the
impact the voltage in order to develop an intuitive understanding of the relationship between magnetic
and electric fields.

Virtual Optics Lab
The Virtual Optics applet is design to help users develop an understanding of how light travels
through a system of lenses and mirrors. Can you create a system that will focus the light at a particular
point on the screen?
