Exponential Acceleration Calculator

(kg/s or N·s/m²)

1. What is the Exponential Acceleration Calculator?

Definition: This calculator computes the acceleration (\( a_y \)) of an object influenced by a resistance factor, using the formula \( a_y = g \cdot e^{\left(-\frac{k}{m}\right) t} \).

Purpose: It helps physicists, engineers, and students model motion with exponential resistance, such as air drag or friction, in fields like mechanics and aerodynamics.

2. How Does the Calculator Work?

The calculator uses the relationship:

\[ a_y = g \cdot e^{\left(-\frac{k}{m}\right) t} \]

Where:

  • \( a_y \) — Acceleration (in m/s², ft/s², or grav)
  • \( g \) — Gravitational acceleration (9.81 m/s²)
  • \( k \) — Resistance proportionality factor (kg/s or N·s/m²)
  • \( m \) — Mass of the object (convertible to kg)
  • \( t \) — Time (convertible to seconds)
  • \( e \) — Base of the natural logarithm (≈ 2.71828)

Explanation: Enter \( k \), \( m \) with its unit, \( t \) with its unit, and the calculator computes \( a_y \) in m/s², ft/s², and grav, accounting for unit conversions.

3. Importance of Exponential Acceleration Calculation

Details: Exponential acceleration models are crucial for understanding motion with resistance, such as terminal velocity scenarios. Units like m/s² and ft/s² are standard, while grav (multiples of g) is useful in aerospace and safety engineering.

4. Using the Calculator

Tips: Enter a positive value for \( k \), select \( m \) and \( t \) units, and click "Calculate." Results show acceleration in m/s², ft/s², and grav (to 2 decimal places, or in scientific notation if less than 0.0001).
