Solve kinematics equations instantly with Acceleration Calculator — the essential physics tool for students, teachers, and engineers. 5 Calculation Modes • Acceleration: a = (v − u) / t • Final Velocity: v = u + at • Initial Velocity: u = v − at • Time: t = (v − u) / a • Distance: s = ut + ½at² Smart Features • Auto-calculate results as you type • Built-in unit conversions for velocity (m/s, km/h, mph), time (s, min), and distance (m, km, ft) • Inline input validation with clear error messages • Tap to copy results to clipboard Velocity–Time Graph Visualize motion with an interactive velocity vs. time chart powered by Swift Charts. See how velocity changes over time for any calculation. Animated Motion Preview Watch a projectile animate across the screen to build intuitive understanding of acceleration and uniform motion. Calculation History Every result is saved automatically. Review past calculations, swipe to delete, or tap to reload values back into the calculator. Formula Reference Quick-access reference sheet with all five kinematic formulas, variable definitions, and unit conversion tables. Designed for Everyone • Clean, minimal interface following Apple Human Interface Guidelines • Full Dark Mode support • Localized in English and Chinese (Simplified) • No ads. No subscriptions. No internet required. Perfect for high school physics, AP Physics, university mechanics, engineering coursework, or anyone who needs a quick kinematics calculation on the go.
