Physical Pendulum Forces 1.0
Gravitational forces simulation. The Physical Pendulum with Forces model displays the gravitational, normal, and friction forces acting on a mass attached to a pivoted rod. These forces cause the mass to accelerate in the radially and tangentially with respect to pivot. Although gravity is always downward, friction and normal force change direction in order to keep the mass in the same position on the stick.Run the simulation and note how...

Vernier Caliper model shows the principle of operation and the physical parts of a Vernier Caliper.The Vernier calipers model has1. an object (Blue) for the internal jaws to measure width of an object with slider to control width of the object and simple drag action to control position of object.2. an object (Green) for external jaws to measure internal diameter of a cylinder for example with slider...

Micrometer Model 1.0
Analyze a micrometer with this tool. The Micrometer Model shows the principle of operation and the physical parts of a real micrometer.?Micrometers use a screw to amplify distances that are too small to measure directly into large rotations of the screw that are big enough to read from a scale. The accuracy of a micrometer derives from the accuracy of the thread that is at its heart. The basic operating principles of a micrometer is that the...

Thick Lens Model 1.0
Lens simulation to help you better understand optics. 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 refraction and its environment, and the height and width of the object as well as the size of the incident light and the horizontal position of...

Wave Function Plotter Model 1.0
Study the one-dimensional wave function with the help of this tool. Wave Function Plotter model displays a one-dimensional wave function u(x,t) depicting a disturbance at position x and time t. The disturbance can be mass density, pressure, or electric field depending on the physical context. The default wave function is sinusoidal but any other analytic function can be entered in the text box. The number of sampling points can also be...

Pendulum simulation to help you with your work.The EJS Pendulum Energy Model shows a pendulum and associated energy bar charts. Users can change the initial starting point of the pendulum. This model is distributed with a middle-school physical science lesson plan.The EJS Pendulum Energy model includes two supplemental documents (see below) that include a middle school lesson plan and a the student version of the program.The Pendulum Energy...

PartitionedBox Model 1.0
Analyze macroscopic systems with this program. The Partitioned Box software displays the number of particles on one half of a box as a function of time after a small hole is made in the partition dividing the box in half. The purpose of this simulation is to gain insight into the tendency of macroscopic systems to approach a well defined equilibrium macrostate and the importance of fluctuations in equilibrium. The software is distributed as a...

Action for the Harmonic Oscillator Model 1.0
Simulate simple harmonic oscillator trajectory. Action for the Harmonic Oscillator model displays the trajectory of a simple harmonic oscillator by minimizing the classical action. The simulation displays the endpoints of the motion (t,x) which can be changed by using the textboxes or dragging, and displays the new trajectory as well as calculates the physical trajectory (that minimizes the action). You can modify this simulation if you have...

Oscillations and Lissajous Figures Model 1.0
Two perpendicular harmonic oscillators motion simulation. Oscillations and Lissajous Figures model displays the motion of a superposition of two perpendicular harmonic oscillators. The simulation shows the result of the superposition. The amplitude and frequency of the oscillators can be changed via textboxes. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model"...

Double Pendulum Model 1.0
Analyze the double pendulum motion with this application. The Double Pendulum model displays the motion of a double pendulum and its Poincare map. A double pendulum is a pendulum with another pendulum attached to its end and the state of this dynamical system is specified by two angles and two angular velocities. Because there is no fiction, the double pendulum is an example of a Hamiltonian system and energy is conserved.?This EJS model...

Faraday Disk Dynamo Model 1.0
Analyze magnetic field with this tool. The EJS Faraday Disk Dynamo shows a conducting disk that rotates in a magnetic field.
