Mechanics Lab is a series of interactive Physics simulations designed for teachers and students in Secondary education (particularly GCSE and A level). Currently it includes simulations of: vectors, friction ramp, simple harmonic motion, orbits, 1D and 2D momentum, projectiles, pendulums, moments and ideal gases.
Further simulations will be added in future updates.
Mechanics Lab is part of the Physics Labs series of apps which also includes Optics Lab and Fields Lab.
