See Einstein Light for a brief introduction to relativistic mechanics.) (* Strictly, we should note that, at very high speeds, a relativistic factor γ must be included: p = γmv. Momentum is a vector because velocity is a vector and mass a scalar. For a particle of mass m and velocity v, the momentum p is m v. Momentum is defined* as the product of mass and velocity. Momentum is the product of mass and velocity The smashing brick problem (separate page).

The importance of the duration of collisions.

Airtrack examples: inelastic collisions.

Momentum conservation can include vector components.Newton's laws and conservation of momentum.Momentum is the product of mass and velocity.It also has some examples not used in the multimedia tutorial. It presents some of the clips and animations with play and pause controls, and it gives some clips of air track collisions, along with their analysis. This page is one of three appendices for the momentum section of Physclips. This page supports the multimedia tutorial Momentum. The paper describes the possibilities of the use of these parameters for reconstruction and will show the injury pattern for motorcyclists in the German traffic accident situation, based on the GIDAS sample in statistical representative manner.Momentum and collisions – background material Momentum is conserved, to a good approximation, in many collisions. Information on final position of vehicles, deformation pattern on vehicles, tire marks and artefacts found on the road like braking and sliding marks, throwing distances of the motorbike rider and the cyclists supplies possibilities for reconstruction of the movement of the human body and determination of collision speed. Different calculations are used by experts, momentum analysis and energy balance. driving and collision speed have to be determined from tire marks and all artefacts at the scene as well as from the final position of vehicles. The paper is describing the methodology of this project with statistically orientated procedure of data sampling on the one hand and will give an overview of procedures for the determination of impact speed on the basis of an on scene investigation on the other hand. The project started on July 1999 and is called 'GIDAS' (German In-Depth Investigation Accident Study). This resulted in Germany in a joint project between FAT (Forschungsvereinigung Automobiltechnik - Automotive Industry Research Association) and BASt (Bundesanstalt für Straßenwesen - Federal Road Research Institute). Since such detailed information is essential for improving the safety of cars, a strong collaboration with automakers developed. The value of on scene in-depth accident research studies has been recognized internationally and many countries worldwide have such teams.
