NEB Physics Practicals — Class 11

This course walks you through the complete NEB Class 11 physics practical syllabus with one working virtual instrument per experiment. You will read a real vernier scale, time a pendulum with your own reflexes, balance forces on a Gravesand board and find the specific heat of a metal — taking readings, filling tables and computing results exactly the way you will in the school lab and the board practical exam. Every formula, least count and source of error matches the standard NEB lab manual.

You will learn: doneReading vernier, screw gauge and spherometer scales doneRecording observations and tabulating data donePlotting graphs and extracting slopes doneEstimating errors and writing precautions doneVerifying laws of mechanics and heat

Lessons

1 straighten Vernier Calipers Grip a sphere, cylinder or beaker in virtual vernier jaws, find the coincident division on the magnified scale and compute the reading — with random zero errors to keep you honest. 3D virtual lab 15 min done 2 cyclone Micrometer Screw Gauge Rotate the thimble until the ratchet clicks on a wire, sheet or even a human hair, then combine the linear and circular scales to read down to 0.01 mm. 3D virtual lab 14 min done 3 lens_blur Spherometer: Radius of Curvature Lower the central screw till it kisses a plane glass, then a watch glass, read the sagitta h on the disc scale and compute R = l²/6h + h/2. 3D virtual lab 15 min done 4 timer Simple Pendulum: Measuring g Time 20 oscillations with a stopwatch that obeys YOUR reflexes, tabulate L and T², plot the graph and pull g out of the slope. 3D virtual lab 18 min done 5 open_with Parallelogram Law of Forces Load three hangers on a Gravesand apparatus, watch the knot settle into equilibrium, and check that the parallelogram of P and Q really balances R. 3D virtual lab 15 min done 6 sledding Coefficient of Friction Tilt an incline until the block just slips to capture the angle of repose, then switch to a spring-balance pull and confirm μ two independent ways. 3D virtual lab 14 min done 7 waves Hooke's Law & Spring Constant Load a spring 50 g at a time, read the pointer on a mm scale, plot F against x and read k off the slope — then test series and parallel combinations. 3D virtual lab 15 min done 8 thermostat Specific Heat by Method of Mixtures Heat a metal piece to 100 °C, drop it into a calorimeter and chase the thermometer to its peak — then balance the heat equation to identify the metal. 3D virtual lab 18 min done
