Elementary math teachers know the importance of this model in teaching the concept of applying distributive property in area model.

The idea is to break one large area (which represents the product of two numbers) into several pieces (products of smaller numbers), then to find the areas of the pieces individually, and finally add to get the area of the whole (the product of the given numbers).

If you or your student or child are having difficulties in learning long division, then you will find this simulation comprehensive and instructional, that guides the learner through the process step by step. This application is for long division with remainder. Another application on long division with float quotient is also available in the simulations section.

With this rich simulation, you can visualize and measure the phase difference between two sound waves using two microphones connected to an oscilloscope. Moreover, you can determine the speed of sound in air by measuring the distance between the two microphones when their waveforms are in phase, taking into account the frequency of the sound wave that is controlled by the sine wave generator.

With this simulation, you can experiment the refraction of light between air and a transparent semi-disk. You can choose the material of the disk from a list of materials. Also, you can determine the index of refraction of the semi-disk when you apply Snell’s law to measurements you take in the simulation.

With this comprehensive and realistic-like photoelectric effect experiment simulation, you will be able to illustrate the following:

The variations of the photocurrent versus potential.

The variations of the photocurrent versus light intensity.

The variation of the kinetic energy of the ejected electrons versus the incident light frequency.

It comes with a graph where you can trace each type of variation as you vary the parameters of the experiment.

Plus, you can experiment and discover more with this simulation.

Using this simulation, you can experience the phenomenon of charging a metallic ball by induction in the first stage and charging the ball by contact in the second stage after the charged rod touches the ball. The displayed charges are for an illustrational purpose, and they are not seen in reality. You can disable the display of charges on the rod and on the ball.

In this simulation, you can try two situations, one in which the rod is positively charged and another in which the rod is negatively charged, and you will see that the two situations result in the same observation.

This is a simple simulation that shows the difference between one-dimensional motion, that can be described by means of one axis, the x-axis, and the two-dimensional motion, that needs an additional axis, the y-axis to be described.
