Acceleration Calculator Plus vs Mean HVAC BS Tools

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.

BS Tools is a toolkit of calculators designed for HVAC and other Building Science (BS) applications, as an alternative to more tedious, manual methods. UTILITIES Single Point Psychrometrics: This calculator provides psychrometric properties of air at a glance. It's great for changing humidity units. Mixed Air Psychrometrics: This calculator provides psychrometric properties of the resulting air of two mixed air streams, e.g. ventilation air mixed with return air. Duct Calculator: In a word, it's a classic 'ductulator'. This tool accepts any two choice inputs among CFM (Air Flow Volume), Duct Diameter, Friction Rate (Head Loss), and Air Velocity. This utility will then provide the other two parameters for you. Uses either a round diameter, or rectangular dimensions. Smallest Zone Calculator: This calculator can be used to gauge how much excess air is acceptable in a heating or cooling system. Bypass Calculator: Paired with the Smallest Zone Calculator, this can tell you how much air you can bypass. Values are unique for cooling and heating (adjustable for altitude). IR Wall Insulation: This calculator can help you estimate the R-Value of a wall, with Infrared (IR) exterior and interior surface, and interior ambient temperatures. Provides a common wall material that best matches your readings with a general degree of confidence in that match. Note included tips on measuring for best results. Parallel R-Value: This calculator provides an overall R-Value (and U-Value) for a wood frame building assembly* (typically a wall), given the R-Values of different materials and their areas or proportions present in the assembly. *Not for use with metal framing. ASHRAE 62.2-2019: Gives ventilation CFM requirements corresponding to ASHRAE 62.2-2019. Fan Run-Time: Simple calculator to calculate ventilation system run time, in min/hr, given the ventilation requirement and fan capacity. Pairs nicely with ASHRAE 62.2 Calculator (and is automatically linked). Note: The above calculators use IP (inch / pound) units. Unit Converter: Converts units. Interpolator: For when you have the number you're looking for at THIS point and THAT point but you're actually somewhere BETWEEN those points.
