Simulation Manual: Elastic Collision in One Dimension

Elastic Collision in One Dimension Simulation Manual

A complete manual for the elastic collision in one dimension simulation, with a mathematical explanation of the derivation of the expressions of the final velocities in terms of the masses and the initial velocities.

Photoelectric Effect Experiment 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.

One-dimensional elastic collision simulation

Elastic Collision in One Dimension Simulation

Using this simulation, you can demonstrate the conservation laws in a one-dimensional elastic collision (The law of conservation of linear momentum and the law of conservation of kinetic energy).

Charging by induction simulation

Charging by induction experiment

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.

One-dimensional and two-dimensional motion simulation

1D and 2D motion simulation

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.

Old simulations

An old simulation illustrating how to determine the speed of sound in air using an oscilloscope, a low frequency generator, a loudspeaker, and two microphones. Developed by Farid Minawi, physics-zone.com. محاكاة قديمة توضح كيفية تحديد سرعة الصوت في الهواء باستخدام راسم الذبذبات ومولد التردد المنخفض ومكبر الصوت وميكروفونين. من إعداد فريد مناوي، موقع، physics-zone.com

These simulations were made using the Adobe Flash/AcrtionScript. You can download them and run then in Windows.

Virtual Oscilloscope

Virtual Oscilloscope

A useful simulation for the students in their studies and for the physics teachers in their presentations of electricity lessons.
The simulation includes alternating generators (AC) and direct generators (DC).
In this simulation, the oscilloscope can display waves coming from generators similar to the real ones.

Free Fall Simulation

Free fall simulation

A new simulation, that simulates the free fall of an object (ball). This simulation gives the ability to measure the acceleration of gravity by taking successive shots of the falling object with recording the time of each shot and measuring the coordinate y for each shot. It also enables us to check the famous free fall equation:
y = (1/2) gt²
