Calculation Formula

E = 0.5 * m * v² * (1 - η/100)

Where:
E = Braking Energy (Joules)
m = Mass of the Car (kg)
v = Initial Velocity (m/s)
η = Braking Efficiency (%)

Result

Braking Energy: 0 J

Learn how to use the Car Braking Energy Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the mass of the car in kilograms (kg).
  2. Enter the initial velocity of the car in meters per second (m/s).
  3. Enter the braking efficiency as a percentage.
  4. Click the "Calculate" button to compute the braking energy.
  5. The result will be displayed in Joules (J).

Working Principle

The calculator uses the formula for kinetic energy to determine the braking energy required to stop a car. The kinetic energy (KE) of an object is given by:

KE = 0.5 * m * v²

Where:

  • m = mass of the car
  • v = initial velocity of the car

The braking efficiency factor adjusts the kinetic energy to account for the efficiency of the braking system. The final formula used is:

E = KE * (1 - η/100)

Where η is the braking efficiency percentage.
