freeCAD is capable of full 3D pan, zoom, tilt and rotate on an assembly of parts in wireframe or rendered graphics. Parts can be solids or DXF file imports. Available solids are extrusions of rectangles, circles, ellipses and polygons. The parts can be positioned and oriented exactly in space, as are markers on the parts. Exact specification of linear and angular velocities of parts in space are also possible. Mass and inertia properties can be user specified or automatically computed based on uniform density. Available joints are spherical (ball), revolute (pin), translational (slider), cylindrical, planar, fixed, universal, point in line, point in plane, parallel, perpendicular, no rotation, constant velocity, rack pinion, screw. Both open and closed 3D loops are permitted. The curve-curve contact allows liftoffs and collisions based on coefficient of restitution. Available actuators are rotational, translational and full six DOF. Their motions are user prescribed functions of time. Forces and torques are user prescribed functions of time, displacements and velocities in all three components or along connecting markers. Example formulas for spring, damper, bushing, beam, aerodynamic, inverse square law and other forces and torques are given. Available functions are sqrt, exp, ln, lg, sin, cos, tan, arctan, arctan2, spline, spectral density. Users can specify constant gravity of arbitrary magnitude and direction.

freeCAD can compute kinematic, quasi-static or dynamic solutions for any interval of time going forward or backward based on the assembly and user requests. It does redundant constraint removal automatically and nondimensionalizes the equations for improved accuracy and stability of models that are microscopic or gigantic. Simulation progress is animated and the simulation can be stopped any time. After simulation, the computed solution can be used for animation or frame by frame analysis. Full 3D pan, zoom, tilt and rotate is available during simulation and animation.

• Free 3d Physics Simulator Games Welcome to NEWTON v4 new version of the award winner NEWTON physics software. Newton provides a completely new way of learning and teaching physics, the exploration of simple machines, mechanisms, kinematics, dynamics, thermodynamics, electricity and optics on a computer in 3D.
• 3D Space Simulator. Celestia lets you explore our universe in three dimensions. Celestia simulates many different types of celestial objects. From planets and moons to star clusters and galaxies, you can visit every object in the expandable database and view it from any point in space and time.
• FreeCAD is another free mechanical simulation software for Windows. It is actually a popular CAD software through which you can create 3D models and simulations.

Users can obtain engineering data in the form of plots and tabular output. XY plots can be zoomed and set to equal scales. Data series available include linear and angular displacements, velocities, accelerations, forces, torques, momenta and kinetic energies. Acceleration data include transverse, centripetal and Coriollis accelerations. Users can view forces and torques from joints, constraints, actuators, springs, dampers, applied forces and inertia. Fourier tranforms of all times series are available. Individual parts can be save into files and reinserted into any assembly repeatedly. Assemblies can be saved in binary or human readable, tab delimited, text format with notes and simulation data for later reload. The text format allows pre and post processing of assemblies by other programs, especially spreadsheet programs. Other specific text formats are for MOSES, PDMS Review and POV-Ray. freeCAD runs on Windows, Linux PC and Mac OS/X. Assembly data are unchanged across platforms.

When teachers are looking to demonstrate some basic physics concepts in the classroom then they will be able to do it more efficiently if they use a physics simulator online. This 3D physics simulation software helps them to teach the children in a virtual physics lab thus helping them to understand the concepts better. Many types of physics simulation software, free download are available online but the commonly used one is particle physics simulation software.

3D simulation is an extension to process simulation using 3D visualization and animation techniques. 3D Simulation enables users to model their actual environment in a virtual computer generated space in order to visualize their models in 3D. Simcad Pro 3D Simulation Software provides an integrated 2D and 3D visualization engine enabling. Physics Simulations is an interactive physics teaching software, which brings the information and computer technologies right where they are mostly needed-in school.
