Physics Toolbox Accelerometer vs Physics Toolkit

Turn your iPhone into a motion laboratory. Physics Toolbox Accelerometer reads the accelerometer built into your device and shows exactly what it measures — live, in three dimensions, in units you can check. MEASURE • G-Force — the ratio of normal force to gravity, in X, Y, Z and total magnitude • Linear Acceleration — the same motion with gravity removed, in m/s² • Spectrum — a live FFT that finds the dominant frequency in a vibration RECORD AND ANALYSE • Record any run to CSV, then replay it with duration, maximum and average • Import CSV files recorded elsewhere and analyse them the same way • Share a recording straight from the app BUILT FOR TEACHING Each mode explains the physics behind it: how a piezoresistive cantilever bends under acceleration, how a capacitive accelerometer varies the electric potential across its plates, and why an object in free fall reads zero g. PRO A single lifetime purchase unlocks the signal filters — moving average, Kalman and low-pass — and analysis of saved and imported recordings. Works on iPhone and iPad, in light and dark, with VoiceOver throughout.

Physics Toolkit is a physics calculator that can be used for physics calculations. It contains many calculators and tables, a list of common formulas and information about all elements. Physics Toolkit is a must-have app for physics students and professionals. Calculators: • Displacement • Acceleration • Newton's second law • Gravitational acceleration • Hooke's law • Momentum • Work • Density • Kinetic energy • Potential energy • Elastic energy • Electric power • Wavelength • Energy conversion efficiency • Pressure • Phase velocity • Static fluid pressure • Dynamic pressure • Buoyancy • Volumeric flow rate • Mass flow rate • Heat capacity • Gravity • Pressure-volume work • Electric current • Ohm's law • Voltage • Voltage in series • Resistance in series • Current in parallel • Resistance in parallel • Resistivity • Capacitance • Capacitor energy • Capacitance in series • Capacitance in parallel • Induction in series • Induction in parallel • Inductor energy • Mass-energy equivalence • De Broglie wavelength • Centrifugal force • Friction • Mechanical advantage • Rotational kinetic energy • Torque • Sound pressure level • Index of refraction • Carnot efficiency • Coulomb's law • Stefan-Boltzmann law Tables: • Formulas • Elements • Base units • Constants • Periodic table • Electron orbitals • Ionization energies • Planck curves • Standard model • Air resistance coefficient • Cosmic microwave background • Greek alphabet
