Physics and Math Applets

 


Fourier Series

Choose a periodic function from the menu or create your own function and compute its Fourier series.  Choose the amount of terms to use in the series and see how the Fourier series approximates the real function.


Mechanical Waves

See how mechnical waves on a string behave when the tension and the mass is changed. Also observe the way the waves reflect on open and closed ends. Different colours of the string represent the tension in those parts.


Simple Pendulum

Discover how simple pendulums work. Vary the different parameters and observe how the pendulum reacts.

Electric Fields

A visualization of electric fields in two dimensions. Drag the charges around to see how the electric field lines change with position. Vary the charges to see how it affects the field as well. The electric potential gradient can also be drawn.


Two Dimensional Collisions

Watch how two dimensional circles collide and react to the collision. Vary the mass and the speed of the circles to see the different effects. Change the coefficient of resitution and watch the energy of the system change over time.


One Dimensional Collisions

Change the mass, initial velocities and coefficient of restitution and discover how the collision affects the momentum, energy and centre of mass of the system.


Projectile Motion

Launch a projectile with different parameters and see how they affect the projectile’s trajectory.


Oscillations

Discover oscillations and their equations of motion. Change the mass, spring constant and drag and watch how the motion of the mass evolves over time.


Wave Functions

Discover the superposition of two travelling waves. Vary the parameters of the individual waves and observe the superposition of the two.


Snell’s Law

Discover Snell’s law. Change the incident angle of the light as well as the index of refraction of the two mediums and see how the reflected and transmitted light are affected.


Matrix Transformations

See how the rotation, translation and scaling matrix work. Change the parameters as well as the order of multiplcation and discover how they effect the final image.


Taylor Series Expansion

See how the different terms of the Taylor Series expansion approximates the true curve. Various functions can be approximated.


Equations of Motion

Watch how the speed and position of a mass change over time according to Newton’s Laws of Motion. Change the initial velocity drag and mass of the object and see how the trajectory changes.
