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. Build, manipulate or investigate real-life 3D physics experiments interactively, solve problems, and more.
A unique feature of Newton is that while it shows real world 3D physical experiments, it is still possible to compare and verify the results with classic formulas. This allows students to establish a clear connection between the real world and its mathematical models, and develops their model creating skills. Another novelty of Newton is the possibility of coupled modeling of mechanics electricity and optics.

The virtual world of NEWTON v4 provides a completely new way of learning physics – the exploration of simple machines, kinematics, dynamics, mechanisms, thermodynamics, electricity and optics on a computer in 3D.

Newton is ruled by the simulated laws of physics, allowing you to build, manipulate and investigate your experiments interactively, without the limitations of physical models.

When creating an experiment in Newton, you can select from a wide range of real world or abstract objects, from the simplest geometrical bodies (brick, sphere, etc.), complex instruments (stands, slope, car, etc.), and constraints (many types of joints and springs).

Select from the wide range of 3D mechanisms elements–axles, wheels, pulleys, gears, racks, levers, cams, screws, transmission belts and more–to discover their working principles. Or study the animated operation of mechanical systems from any viewpoint using Newton’s powerful 3D engine. In addition, you can either assemble the mechanisms step by step or watch the assembly process as an interactive movie.

You can adjust their physical parameters (mass, elasticity, friction, etc.); assign to them forces, torques or velocity; and make relationships subject to constraints. You can add virtually any object to Newton using a VRML editor; you may also export your experiments in VRML format

Newton Version 4 provides a unique new 3D environment for learning optics. With Newton it is possible to set up different optical systems, and show a realistic view with Newton's raytrace engine.

With the example files included, it's easy to get started. You can alter them and simulate again, and you will see that it's quite simple to create amazing demonstrations. When running a simulation, the bodies start moving, guided by the acting constraints; are rotated by torques; and collide with each other as in a movie.

Actually, you can set up one or more cameras and capture their views of the experiment, storing them in an AVI file. You can also add descriptions to your examples, with explanatory texts, images, and formulas.

Using diagrams, it’s easy to measure and evaluate the results of your experiments. Several user-defined curves can be displayed on the same diagram, so it's easy to compare the measured data with the results derived from theoretical calculations. You may also change the units of the physical quantities.
