Léngkah mangrupikeun simulator fisik interaktif. Éta ngamungkinkeun anjeun ngajalajah dunya fisik ngalangkungan simulasi. It works like this: you place some bodies on the scene, add some forces such as gravity or springs, then click Simulate and Step shows you how your scene will evolve according to the laws of physics. You can change every property of the bodies/forces in your experiment (even during simulation) and see how this will change evolution of the experiment. Kalayan Léngkah anjeun henteu ngan ukur tiasa diajar tapi ngaraosan kumaha cara fisika!

Fitur:

• Simulasi mékanis klasik dina dua diménsi
• Partikel, cinyusu kalawan gaya damping, gravitasi jeung coulomb
• Awak kaku
• Deteksi tabrakan (ayeuna ukur diskrit) sareng penanganan
• Awak lemes (deformable) disimulasikeun salaku sistem partikel-spring anu tiasa diédit ku pangguna, gelombang sora
• Molecular dynamics (currently using Lennard-Jones potential): gas and liquid, condensation and evaporation, calculation of macroscopic quantities and their variances
• Units conversion and expression calculation: you can enter something like “(2 days + 3 hours) * 80 km/h” and it will be accepted as distance value (requires libqalculate)
• Errors calculation and propagation: you can enter values like “1.3 ± 0.2” for any property and errors for all dependent properties will be calculated using statistical formulas
• Estimasi kasalahan Solver: kasalahan diwanohkeun ku solver diitung sarta ditambahkeun kana kasalahan-diasupkeun pamaké
• Sababaraha solvers béda: nepi ka urutan 8th, eksplisit jeung implisit, kalawan atawa tanpa timestep adaptif (seuseueurna solvers merlukeun perpustakaan GSL)
• Alat controller pikeun gampang ngadalikeun sipat salila simulasi (sanajan ku potong kompas keyboard custom)
• Alat pikeun ngabayangkeun hasil: grafik, méter, tracer
• Inpo kontéks pikeun sakabéh objék, browser wikipedia terpadu
• Kumpulan ékspérimén conto, langkung seueur tiasa diunduh sareng KNewStuff
• tutorials terpadu
