Physics Motion API

salutare 4,223 Abbonati

Classical-mechanics maths as an API. The kinematics endpoint is a full SUVAT solver: give any three of initial velocity (u), final velocity (v), acceleration (a), time (t) and displacement (s) and it computes the rest using the standard constant-acceleration equations. The projectile endpoint takes a launch speed and angle (and an optional launch height and gravity) and returns the horizontal and vertical velocity components, the time to the peak, the maximum height, the total flight time, the range and the impact speed. The free-fall endpoint computes a vacuum fall from a height or for a time, with an optional initial velocity, returning the fall time, distance and impact velocity. Gravity defaults to standard 9.80665 m/s² but can be set for the Moon, Mars or any body. Everything is computed locally and deterministically in SI units, so it is instant and private. Ideal for physics education and homework, engineering and simulation, game and ballistics development, and motion tools. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is motion physics; for planetary data use a planets API and for unit conversion use a unit API.

Center of Mass API

Centre-of-mass and barycentre mechanics as an API, computed locally and deterministically. The point-masses endpoint computes the centre of mass of a system of point masses in one, two or three dimensions, applying x_com = Σ(m_i·x_i)/Σm_i to each axis from a list of masses and their x (and optional y and z) coordinates — masses of 1, 2 and 3 at positions 0, 1 and 2 give a centre of mass at 1.333, and four equal masses at the corners of a square sit at its centre. The two-body endpoint computes the barycentre of two masses separated by a distance, r1 = d·m2/(m1+m2) from the first body, which always lies closer to the heavier one — for the Earth-Moon system the barycentre is about 4 670 km from Earth’s centre, still inside the planet. Lists may be passed as comma-separated values (masses=1,2,3&x=0,1,2) or as JSON arrays in a POST body, and units are consistent and unit-agnostic. Everything is computed locally and deterministically, so it is instant and private. Ideal for physics, engineering-statics, astronomy, robotics, game-physics and mechanics-education app developers, balance-point and barycentre tools, and simulation software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 endpoints. This is the centre of mass; for the rotational moment of inertia use a moment-of-inertia API.

API de Frenado de Vehículos

Física de frenado de vehículos como API, calculada local y determinísticamente. El endpoint de distancia de frenado calcula la distancia total para detener un vehículo como la suma de la distancia de reacción que el vehículo recorre durante el tiempo de reacción del conductor, v·t, y la distancia de frenado v²/(2·μ·g) — que crece con el cuadrado de la velocidad, por lo que duplicar la velocidad cuadruplica la distancia de frenado — a partir de la velocidad, el coeficiente de fricción neumático-carretera, el tiempo de reacción y la pendiente de la carretera, junto con la desaceleración y el tiempo hasta detenerse. El endpoint de fuerza de frenado calcula la fuerza de frenado F = m·a y la desaceleración de un vehículo, ya sea a partir de una parada en una distancia dada (a = v²/2d) o del coeficiente de fricción (a = μ·g), con la energía cinética que debe disiparse como calor. El endpoint de velocidad de derrape reconstruye la velocidad al inicio de un derrape a partir de la longitud de la marca de derrape, v = √(2·μ·g·d), una estimación de límite inferior utilizada en reconstrucción de accidentes. La velocidad está en km/h por defecto (también m/s o mph), la masa en kg y las distancias en m; el asfalto seco tiene μ ≈ 0.7, mojado ≈ 0.4 y hielo ≈ 0.1. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones automotrices, de seguridad vial, flotas, telemática y reconstrucción de accidentes, herramientas de distancia de frenado y forenses, y educación en física. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es frenado de vehículos; para cinemática general use una API de cinemática y para un objeto en una pendiente use una API de plano inclinado.

Circular Motion API

Uniform circular-motion physics as an API, computed locally and deterministically. The centripetal-force endpoint computes the centripetal acceleration a = v²/r = ω²·r — always pointing toward the centre — and the centripetal force F = m·a that holds a body on its circular path, from the mass, the radius and either the linear or the angular velocity, and reports the equivalent g-force. The angular endpoint converts between every way of describing rotation — angular velocity (rad/s), revolutions per minute, frequency, period and, given a radius, the linear (tangential) velocity — using ω = 2π·f = 2π/T = v/r. The centrifuge endpoint computes the relative centrifugal force (RCF, in g) of a centrifuge rotor from its speed in rpm and radius, RCF = ω²·r / g, or inverts it to give the rpm needed to reach a target RCF. Masses are in kg, radii in m (mm for the centrifuge), velocities in m/s, angular velocities in rad/s and forces in N. Everything is computed locally and deterministically, so it is instant and private. Ideal for physics-education, mechanical, automotive, lab-centrifuge and amusement-ride app developers, rotational-motion and g-force tools, and STEM teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is uniform circular motion; for gravitational orbits use a gravitation API, for a vehicle on a banked curve a banked-curve API and for pendulum oscillation a pendulum API.

Nuclear Physics API

Nuclear-physics maths as an API, computed locally and deterministically. The binding-energy endpoint computes a nucleus's mass defect, Δm = Z·m_H + N·m_n − M_atom, and its binding energy E = Δm·c² (1 u = 931.494 MeV) and binding energy per nucleon, from the proton and neutron counts and the measured atomic mass. The semf endpoint estimates the binding energy from the semi-empirical (Bethe-Weizsäcker) mass formula, breaking it into the volume, surface, Coulomb, asymmetry and pairing terms, from just the mass number and proton number. The q-value endpoint computes the energy released or absorbed in a nuclear reaction from the masses of the reactants and products, Q = (Σm_reactants − Σm_products)·c², classifying it as exothermic (fusion of light nuclei or fission of heavy ones) or endothermic. Masses are in atomic mass units and energies in MeV and joules. Everything is computed locally and deterministically, so it is instant and private. Ideal for physics-education, nuclear-engineering, astrophysics and science app developers, reactor and reaction tools, and STEM teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is nuclear binding and reactions; for radioactive decay use a half-life API and for atomic energy levels a quantum API.
