Virtual Physics Lab
Moment of a Force τ = F × d
A complete interactive lab to feel how forces produce rotation. Sliders, drag-handles, glowing arrows and live graphs — built for school and college students of mechanics.
Torque Laboratory
Adjust F, d and direction. Watch the rod respond in real time with live graphs and formulas.
Open →InteractiveRotation Explorer
Drag the point of application and the force direction on a glowing pivoted disc.
Open →CompareLinear vs Rotational
Same impulse, different motions — compare a ball and a pivoted wheel side by side.
Open →Real lifeEveryday Examples
Door, spanner, steering wheel, grinder, pedal and fodder cutter — all explained by τ = F × d.
Open →PlayChallenges
Solve four torque puzzles. Find the smallest force, the best length, the right point.
Open →TestQuiz
Random MCQs with instant feedback to test your intuition.
Open →LearnTheory
From linear to rotational motion, units, sign conventions and worked examples.
