Step is an interactive physical simulator. It allows you to explore the physical world through simulations. 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. With Step you cannot only learn but feel how physics works!

Fitur:

• Classical mechanical simulation in two dimensions
• Particles, springs with damping, gravitational and coulomb forces
• Rigid bodies
• Collision detection (currently only discrete) and handling
• Badan alus (deformable) simulasi minangka sistem partikel-springs sing bisa diowahi pangguna, gelombang swara
• Dinamika molekuler (saiki nggunakake potensial Lennard-Jones): gas lan cairan, kondensasi lan penguapan, pitungan jumlah makroskopik lan varians.
• Konversi unit lan pitungan ekspresi: sampeyan bisa ngetik kaya "(2 dina + 3 jam) * 80 km / jam" lan bakal ditampa minangka nilai jarak (mbutuhake libqalculate)
• Pitungan lan panyebaran kesalahan: sampeyan bisa ngetik angka kaya "1.3 ± 0.2" kanggo properti apa wae lan kesalahan kanggo kabeh sifat sing gumantung bakal diwilang nggunakake rumus statistik
• Estimasi kesalahan solver: kesalahan sing diwenehake dening solver diwilang lan ditambahake menyang kesalahan sing dilebokake pangguna
• Sawetara solver sing beda: nganti urutan kaping 8, eksplisit lan implisit, kanthi utawa tanpa timestep adaptif (sebagéan gedhé pemecah mbutuhake perpustakaan GSL)
• Alat pengontrol supaya gampang ngontrol properti sajrone simulasi (sanajan nganggo trabasan keyboard khusus)
• Alat kanggo nggambarake asil: grafik, meter, tracer
• Informasi konteks kanggo kabeh obyek, browser wikipedia terpadu
• Koleksi conto eksperimen, luwih akeh bisa didownload nganggo KNewStuff
• Tutorial terpadu
