摘要: We introduce a new method of determining the coefficient restitution (COR) ball–surface combination by using sound produced impact/collision ball with surface. Using digital electronic circuit, electrical signal is amplified and fed to storage oscilloscope through relay circuit for measuring time interval between two successive collisions This then used determine COR.
