Impact Force Calculator

Step-by-Step Guide to Using the Impact Force Calculator

The Impact Force Calculator is designed to compute various impact-related metrics such as impact velocity, kinetic energy at impact, peak impact force, impact acceleration, and G-force. Follow these steps to use the calculator effectively.

Step 1: Input Object’s Mass

Begin by entering the mass of the object in kilograms. Ensure that the value is between 0.001 kg and 100,000 kg. This field is required, and the input should be in steps of 0.001 kg.

Step 2: Enter Drop Height

Proceed to input the height from which the object will be dropped, in meters. This required input should range from 0.01 meters to 1,000 meters, with a precision up to two decimal places (step of 0.01 m).

Step 3: Specify Deformation Distance

Next, enter the deformation distance in meters, which corresponds to the distance the object penetrates upon impact. This value must be between 0.001 meters and 10 meters and is necessary for the calculation. Ensure accuracy by entering the value in steps of 0.001 meters.

Step 4: Select Impact Surface Type

Choose the impact surface type from the available options. These surfaces include:

• Rigid (Concrete/Steel) with a factor of 0.25
• Semi-Rigid (Wood) with a factor of 0.50
• Semi-Soft (Rubber) with a factor of 0.75
• Soft (Foam) with a factor of 0.90

This choice is required to determine the extent of the impact force depending on the surface type.

Step 5: Calculate and Review Results

Once all the necessary inputs have been provided, the calculator will automatically compute the following results:

• Impact Velocity: This is calculated using the formula sqrt(2 * 9.81 * height) and displayed in meters per second (m/s).
• Kinetic Energy at Impact: Calculated as 0.5 * mass * pow(impactVelocity, 2) and shown in Joules.
• Peak Impact Force: Determined using the formula (mass * 9.81 * height) / (deformationDistance * surfaceType), represented in Newtons (N).
• Impact Acceleration: This result is calculated as impactForce / mass and given in meters per second squared (m/s²).
• G-Force: Finally, the G-Force is computed using impactAcceleration / 9.81 and expressed in Gs.

Each result field will provide values formatted with two decimal places for precision and clarity. Review these results to understand the dynamics of the impact event under specified conditions.
