Master classical kinematics, Omni-Solver variable resolution, G-force telemetry, and velocity-time integrals.
Choose Physics or Automotive Mode
Switch between 'Standard Physics' (for mechanics homework, laboratory experiments, and kinematics) and 'Automotive Diagnostic' (for 0-100 km/h or 0-60 mph vehicle acceleration and braking tests).
Input Any 3 Known Variables
Type values into any 3 fields among Initial Velocity (vi), Final Velocity (vf), Acceleration (a), Time (t), or Distance (d). The Omni-Solver engine automatically locks your 3 inputs.
Select Preferred Measurement Units
Customize units for each variable independently: velocities in km/h, mph, or m/s; acceleration in m/s², G-force, or mph/s; distance in meters, feet, kilometers, or miles; time in seconds, minutes, or hours.
Load Real-World Vehicle Presets
In Automotive mode, open the vehicle preset selector to load performance benchmarks for production cars (Tesla Model S Plaid, Porsche 911 Turbo S, Bugatti Chiron, F1 Car, or Hard Braking).
Analyze G-Force Scale & Velocity Graph
Inspect the real-time G-force bar compared against real-world benchmarks (jet takeoff, rollercoasters, F-16 fighter jets) and study the velocity-time area graph where the shaded area equals total distance.

Frequently Asked Questions (FAQ)
Kinematic equations, acceleration concepts, G-force conversions, and vehicle performance physics.
QWhat is acceleration and how is it defined in physics?
Acceleration is the rate of change of velocity with respect to time: a = Δv / Δt = (vf - vi) / t. It is a vector quantity having both magnitude and direction, measured in meters per second squared (m/s²) in the International System of Units (SI).
QWhat are the 4 fundamental kinematic equations of motion?
Under constant acceleration, motion is governed by: 1) vf = vi + at; 2) d = vi*t + 0.5*a*t²; 3) vf² = vi² + 2ad; and 4) d = ((vi + vf) / 2) * t. The Omni-Solver examines which 3 variables you enter and automatically selects the correct equation to solve for the remaining 2.
QWhat is G-force and how does it convert to m/s²?
G-force is a unit of acceleration relative to Earth's standard gravitational acceleration at sea level: 1 G = 9.80665 m/s². An acceleration of 2 G means you are accelerating at twice Earth's gravity (≈ 19.61 m/s²), subjecting your body to twice your normal weight in inertial force.
QWhat is the difference between acceleration and deceleration?
Acceleration refers to any change in velocity. When a body speeds up in its direction of travel, acceleration is positive. Deceleration (often called negative acceleration or braking) occurs when the acceleration vector opposes the direction of velocity, causing the object to slow down (vf < vi).
QWhy does the shaded area under the Velocity-Time graph represent distance?
In calculus and physics, displacement is the definite integral of velocity over time: d = ∫ v(t) dt. For constant acceleration, the graph forms a trapezoid between time 0 and t. The geometric area of this trapezoid ((vi + vf) / 2) × t exactly equals the distance traveled.
QHow do you calculate acceleration from 0 to 100 km/h or 0 to 60 mph?
First convert velocity to m/s: 100 km/h = 27.78 m/s, and 60 mph = 26.82 m/s. Then divide by elapsed time: a = (vf - vi) / t. For example, a car accelerating from 0 to 100 km/h in 3.0 seconds achieves an average acceleration of 27.78 / 3.0 = 9.26 m/s² (approx. 0.94 G).
QCan an object have zero velocity but non-zero acceleration?
Yes. When a ball is thrown vertically upwards, at the apex of its trajectory its instantaneous velocity is momentarily 0 m/s, yet its acceleration is constantly 9.81 m/s² downward due to gravity. Similarly, a car at rest just as the driver depresses the throttle has v = 0 with maximum acceleration.
QWhy are all internal calculations performed in SI units?
Physical equations are dimensionally consistent only when standard units are used. Converting all velocities to m/s, distances to m, and times to s eliminates unit mismatch errors. The calculator then accurately reconverts the output to your chosen display unit.
