Orbit Xplorer 2.0
Educational orbit and gravitation simulator for high school, college and beginning university physics and astronomy. Input mass, radius, coordinates and velocity components of 2 to 10 bodies manually or by dragging and dropping predefined bodies. Then watch how the orbits evolve under the mutual gravitaional attractions. Save and print the simulation. Great for 'lab exercises' in gravitational physics or for verifying numerical answers to textbook problems. Includes 29 introductory to advanced premade simulations with activities page in html-format. Simulations include elliptical satellite orbits, Kepler's laws, double star, geocentric and heliocentric world view, Lagrange points, gravity assist, Hohmann orbit, extrasolar planet, inner solar system. Uses actual pictures of planets. Plot orbits in a plane or in 3D. View time, distances, speeds, accelerations, energies and acceleration vectors as they change. Adjust the simulation speed to fit your computer. Zoom and change parameters during the simulation. Run up to four simultaneous simulations. Tutorial and context-sensitive help included.
LAB Fit Curve Fitting Software
Curve fitting (fit), nonlinear regression, treatment of data, basic statistics, error propagation, 2D and 3D graphs, confidence band, uncertainty, error bars, extrapolation, chi-square, correlation coefficient tests, covariance matrix, math tools.
Two Channels Frequency Generator
Allows independent control of frequency,phase and volume on left and right channels.Measured data points can be easily captured for storage and later statistical analysis.The perfect tool for psychophysics and psycho-acoustics laboratory experiments
1D Heat Transfer
The 1D Heat Transfer software is used for to study one-dimensional heat transfer (steady and unsteady states). It can be used for the geometries: wall, Lx = width; long cylinder, Lx = length; sphere, Lx = R/3 and semi-infinite wall.
