Ac Adapter By Model
Gnomon Model v.1.0
The EJS Gnomon model simulates the shadow cast by a gnomon (the part of a sundial that casts the shadow) over the course of a day for any day of the year and any latitude on Earth. The software gives you the option to use mean Sun (which moves relative ...
Coupled Oscillators and Normal Modes Model v.1.0
Coupled Oscillators and Normal Modes model displays the motion of coupled oscillators, two masses connected by three springs. The initial position of the two masses, the spring constant of the three springs, the damping coefficient for each mass, and ...
Noon Shadow Model v.1.0
The Noon Shadow model shows the geometry of the shadow cast by a gnomon at noon. Users can change the orientation of the gnomon as well as its latitude. The height of the gnomon and its shadow length are displayed in Earth radius units.Noon Shadow model ...
Standing Waves on a String Model v.1.0
Standing Waves on a String model displays the motion of a standing wave on a string. The standing wave can be augmented by adding the zero line and the maximum displacement of the string. The number of standing waves shown can be changed via a slider.
Rail Gun Model v.1.0
Rail Gun Model simulates a rail gun created by running current through long rods generating a magnetic field that accelerates a current-carrying cross-rod. The simulation shows the generated magnetic field. Users can adjust the current in the rails and ...
Thick Lens Model v.1.0
Thick Lens model allows the user to simulate a lens (mirror) by adjusting the physical properties of a transparent (reflecting) object and observing the object's effect on a beam of light. The user can adjust the concavity of the sides, the index of ...
Light and Shadow Model v.1.0
Light and Shadow Model shows light that either passes through a mask with a hole in it, or it is blocked by an object, as it travels to a screen on the right. The user can turn on and off two light bulbs (red and blue) and drag the bulbs around the screen ...
Phases of Venus Model v.1.0
Venus Phases model shows the shadows cast by two gnomons at different locations on Earth. For one gnomon the sun is directly overhead (as would be the case if the gnomon was on the Tropic of Cancer at the summer solstice). The other gnomon is due north ...
Molecular Dynamics Adiabatic Piston Model v.1.0
Molecular Dynamics Adiabatic Piston model shows two gas samples within a horizontal cylinder that is divided by an insulated piston that moves without friction. Initially the piston is held (locked) in place, and the pressures of the gases on each side ...
Magnetic Field from Loops Model v.1.0
The EJSMagnetic Field from Loops model computes the B-field created by an electric current through a straight wire, a closed loop, and a solenoid. Users can adjust the vertical position of the slice through the 3D field.The Magnetic Field from Loops ...
Heating and Cooling a Cylinder Model v.1.0
Heating and Cooling a Cylinder model computes the radial temperature distribution within a long cylinder as it is heated and cooled by a surrounding fluid. The cylinder is broken into shells and the temperature of each shell is computed using a finite ...
Faraday Loop Model v.1.0
Faraday Loop Model shows a conducting loop in a time-dependent constant magnetic field. The model is initially incomplete and students must complete the model by adding the appropriate equations. If Ejs is installed, right-clicking within the plot and ...
Kinematics of a Translating and Rotating Wheel Model v.1.0
Kinematics of a Translating and Rotating Wheel model displays the model of wheel rolling on a floor. By controlling three variables, the kinematics of the wheel can be changed to represent sliding, rolling with sliding, rolling without slipping, rolling ...
Ceiling Bounce Model v.1.0
Ceiling Bounce Model shows a ball launched by a spring-gun in a building with a very high ceiling and a graph of the ball's position or velocity as a function of time. Students are asked set the ball's inital velocity so that it barely touches the ceiling.
Sliding Down an Incline Plane Model v.1.0
Sliding Down an Incline Plane Model analyze static friction. This interactive simulation shows a stone block lying at rest on an inclined plane. Initially, the component of gravity along the plane surface is exceeded by the force of static friction. The ...
