In this episode of the Physics World Weekly podcast, collision expert Michael Hall explains how Newtonian physics is used to piece together what happened in motor vehicle accidents, sometimes revealing insurance fraud. Hall is a physicist and head of research at GBB – a company in Preston, UK, that provides impartial scientific, forensic and engineering advice on traffic collisions. He has also written an article for Physics World about the physics of car crashes. It is called “Using Newton’s laws to weed out bogus car-crash claims”.

Also in this episode, Physics World’s Margaret Harris reports back from the 2022 Institute of Physics Business Awards gala, where seven companies were honoured for their innovations. These include two firms that make technologies for diagnosing cancer and a company that has just won a £60m contract to build a quantum computer.
