Elastic Collision Calculator

The Elastic Collision Calculator helps users compute the final velocities of two colliding objects, their initial and final kinetic energies, and the energy loss and its percentage, based on input masses, velocities, and the coefficient of restitution.

How to Use the Elastic Collision Calculator

The Elastic Collision Calculator is designed to help you compute the final velocities and kinetic energies after an elastic collision between two objects. Follow these simple steps to use the calculator effectively:

Input Fields

  1. Mass of Object 1 (kg): Enter the mass of the first object. Ensure that the value is greater than 0.0001 kg. Use the placeholder as a guide, and input the mass with an increment of 0.0001 kg.

  2. Initial Velocity of Object 1 (m/s): Provide the initial velocity of the first object. This value can be a positive or negative number, depending on the direction of motion, and should be input in increments of 0.01 m/s.

  3. Mass of Object 2 (kg): Enter the mass for the second object, similar to Object 1. The mass must be more than 0.0001 kg, and the input must be in increments of 0.0001 kg.

  4. Initial Velocity of Object 2 (m/s): Input the initial velocity of the second object using increments of 0.01 m/s.

  5. Coefficient of Restitution: Enter a value between 0 and 1. The coefficient of restitution accounts for the elasticity of the collision, where 1 represents a perfectly elastic collision.

Result Fields

After providing all input data, the calculator computes the following:

  1. Final Velocity of Object 1: The calculated final velocity of the first object after the collision, displayed in meters per second (m/s) with three decimal places.

  2. Final Velocity of Object 2: The calculated final velocity of the second object, also shown in m/s with three decimal precision.

  3. Initial Total Kinetic Energy: Displays the total kinetic energy before the collision in Joules (J), calculated to three decimal places.

  4. Final Total Kinetic Energy: Displays the total kinetic energy after the collision, also in Joules (J) and with three decimal places.

  5. Energy Loss: Indicates the amount of energy lost if any, during the collision. This is shown in Joules (J) and calculated to three decimal places.

  6. Energy Loss Percentage: Shows the percentage of the initial kinetic energy lost through the collision, formatted to two decimal places.

By inputting the appropriate values and following these steps, you can accurately determine the outcomes of an elastic collision using this calculator.
