 Non-inertial Frames

Pendulum in a Lift

Apply horizontal and vertical lift acceleration and watch effective gravity shift the equilibrium direction and change the oscillation period.

Standing Waves on a String

Change harmonic number, string length and wave speed to explore how nodes, antinodes, wavelength and frequency relate on a fixed string.

Open simulation →
 Torque

Torque & Moment-Arm Explorer

Adjust force, distance from the pivot, and angle to see how the perpendicular moment arm determines torque magnitude and direction.

 Torque

Balance a Loaded Beam

Move supports and point load along a beam to explore how reaction forces satisfy rotational and translational equilibrium simultaneously.

Open simulation →
 Moment of Inertia

Parallel-Axis Theorem

Shift the rotation axis away from the center of mass and watch I = ICM + Md² grow as a parabola in the displacement d.

Open simulation →
 Moment of Inertia

Rolling Race: Hoop vs Disc vs Sphere

Release three objects on identical inclines and see how rotational inertia determines acceleration and finishing order.

Open simulation →
 Thermodynamics

First-Law Accounting

Set heat and work transfers and watch how ΔU = Q − W updates the system's internal energy, with signed arrows and accounting bars.
