The Physics of Motorcycle Crashes
Riding a motorcycle can bring an inexpressible sense of freedom, but it comes with substantially higher risks than driving a car. Because you’re unprotected by a metal framework, seatbelts, and airbags, even a minor collision can result in serious injuries. But why does the lack of these features make motorcyclists prone to serious injury? The physics of motorcycle accidents can help explain. THE FIRST LAW OF MOTION
Motorcyclists’ heightened vulnerability to injury can be explained by inertia. According to the law of inertia, an object in motion tends to stay in motion unless acted upon by an external force. If a car drives along a road and then crashes into a tree, the vehicle will abruptly stop. However, the car’s occupants will continue moving at the same rate as the car’s former speed until their trajectory is changed by an external force, such as a seatbelt. By contrast, a biker in a motorcycle crash has no seatbelt or metal frame to arrest their motion. The external force stopping their trajectory will likely be the road or another heavy object, such as a tree or car. When the biker hits the object, they’ll either come to an abrupt stop or skid to a halt. Either way, the impact force and friction can result in severe injuries, from lacerations to fractures to traumatic brain injury.
