Kinematics & Dynamic Acceleration in Physics
Acceleration is the rate of change of velocity with respect to time). Since velocity is a vector, an object accelerates whenever its speed changes, its direction changes, or both.
The Three Types of Acceleration
- Linear Acceleration: Change in speed along a straight path (speeding up or braking).
- Centripetal Acceleration: Change in direction along a curved circular path), directed toward the center of curvature.
- Gravitational Free-Fall: Acceleration caused by gravity near Earth's surface).
How to Use This Calculator
Enter your Acceleration Kinematics Formula — choose from Velocity Change over Time (a = (vf - vi) / t), Velocities over Distance (a = (vf² - vi²) / 2d), Newton's 2nd Law (a = F / m), Initial Velocity (vi in m/s) (e.g. 0), Final Velocity (vf in m/s) (e.g. 27.78 (100 km/h)), Time Duration (t in seconds) (e.g. 5.0), Distance (d in meters, for mode 2) (e.g. 100), Applied Force (F in Newtons, for mode 3) (e.g. 3000), Mass (m in kg, for mode 3) (e.g. 1000), and Turn / Curve Radius (r in meters, for Centripetal) (e.g. 50). Verify your units match the formula standard (SI vs imperial) before entering values.
The Formula
Universal kinematic and dynamic acceleration formulas:-Time Formula: a = (Δ v) / (Δ t) = (v_f - v_i) / (t)-Distance Formula (Torricelli): a = (v_f^2 - v_i^2) / (2d)'s Second Law: a = F_netm Radial Acceleration: a_c = (v^2) / (r)-Force: g = (a) / (9.80665 m/s^2)
Worked Example
For example, a car accelerating from 0 to 100 km/h in 5.0 seconds: . In imperial units, this equals 0.567 g's, gains speed at and completes 0 to 60 mph in 4.83 seconds.
Understanding Your Result
Kinematic reference values: Speed of light 3×10⁸ m/s (c), speed of sound in air at 20°C 343 m/s, speed of sound in water 1,480 m/s, Earth's orbital speed 29.8 km/s. Acceleration due to gravity (g) = 9.81 m/s² at sea level (varies 9.78 at equator to 9.83 at poles). Relativistic effects become measurable above ~10% of the speed of light — classical kinematic formulas apply for everyday speeds. Unit conversions: 1 m/s = 3.6 km/h = 2.237 mph.
