Car Crash Impact Force Calculator
How to calculate impact force? G-force in car crashes. Impact force formulas we used above describe an ideal collision between two objects. In the real situation of a car crash, the profile of force during the accident can be more extensive e.g., you should take into account that car collapses and that a human is not a point mass but a complex body.
Impact Force Engineering ToolBox
The impact on a human body can be difficult to determine since it depends on how the body hits the ground which part of the body, the angle of the body and/or if hands are used to protect the body and so on. For this example we use an impact distance of 3/4 inch (0.0625 ft) to calculate the impact force: F avg = (800 ft lb) / (0.0625 ft

Meanwhile, the energy absorption increased to 37920, J, accounting for 23.7% of the total energy, there has been a significant improvement. In re-ducing the front longitudinal beams bending deformation and enhancing crushing deformation, at the same time,
Impulse of Force
Minimizing Impact Force. The process of minimizing an impact force can be approached from the definition of the impulse of force: . If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor. This principle is applied in many common-sense situations:

Rotational forces and internal strains are likely to be reduced by the crushing. In a lab test, graphs of the impact energy the brain sees look like this, with a smooth curve extending over 6ms for the good helmet and a huge spike like the one below for a bare head. About half way up that spike is where permanent brain damage begins.
