When there was a car accident involving a motorcycle, it is crucial to determine the velocity before the collision. The sliding motorcycle after a collision finally come to a halt because of kinetic frictional force that exists between the moving objects and the roads. If we know the total sliding distance of a motorcycle we can calculate the speed just before the collision by a simple physical formula. For that we should know the sliding frictional coefficients of the motorcycle on the sliding surface. In this paper we inferred sliding frictional coefficients of motorcycles under various conditions by pulling it. As various sliding conditions, three kinds of sliding surfaces, two kinds of pulling velocities and two kinds of motorcycles are applied for comparison. By statistical analysis, it revealed that the frictional coefficients are highly dependent on all three factors including sliding surface, sliding velocity and motorcycle model. Hence the results should be carefully applied for accident investigations.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
