Things you can pull, drag and break. Each simulation works on a phone and maps to a topic in the school science & maths curriculum.
Class 9 · Physics Work & energy Free
Reshape the track and watch kinetic, potential and thermal energy trade places. Change mass, friction and gravity.
Class 9 · Physics model building Free
make the batsman hit the ball, you guess where will it land.
Class 11 · Physics units and measurement Free
type any measurement and see which digits are significant and which only hold the place, with the reason for each.
Class 11 · Physics units and measurement Free
combine two measured values and see why the answer cannot be more precise than the roughest input.
Class 11 · Physics units and measurement Free
build the dimensional formula of each side of an equation and see whether they match, catching a wrong formula early.
Class 12 · Physics electric charges and fields Freedrag two charges, change their signs and sizes, and watch the force grow, shrink and flip as the inverse-square law plays out.
Class 12 · Physics electric charges and fields Free
place positive and negative charges and see the electric field drawn as field lines or an arrow grid.
Class 12 · Physics electric charges and fields Free
move a charge in and out of a closed surface and watch the flux, seeing that only the charge enclosed matters.
Class 8, 12 · Physics electric charge Free
charge the electroscope by touching it with a charged rod, and watch the two gold leaves repel and spread apart as like charges push each other away.
Class 12 · Physics electric charges and fields Freeplace charges on the corners, edges and centre of a regular polygon and see the net force on every charge build up as the vector sum of all the others.
