Manipulate the important variable and watch the system respond immediately.
Interactive simulations that make the theory visible. Each one lets you play with the concept and watch how it behaves — built to grow intuition, not to hand out numbers.
Each PracticeNEET simulation connects a student action to the correct theoretical response. Move a magnet and the induced current changes direction. Move an object across a focus and the ray diagram changes from a real image to a virtual one. The animation is driven by the concept, so students can test predictions instead of passively watching a loop.
Manipulate the important variable and watch the system respond immediately.
Test ideas such as “a nearby magnet always induces current” and see why they fail.
Relate textbook laws and ray constructions to visible motion and state changes.
These experiences show direction, relative strength, image nature and other theory-backed relationships. We do not label illustrative screen distances or animation strengths as measurements. When a simulation uses an ideal model—such as paraxial ray optics—the page states that scope clearly.
Concept simulations are interactive visual models that let students manipulate an object or condition and immediately observe how the physics or chemistry responds. They complement theory and problem practice by making cause and effect visible.
No. PracticeNEET's concept simulations prioritise correct relationships, directions and state changes. They deliberately avoid uncalibrated numerical readouts that could be mistaken for measured values.
The current collection includes electromagnetic induction and a ray optics bench covering convex and concave lenses and mirrors. More Physics and Chemistry simulations are being added.
