Basketball Surfaces and Coefficient of Restitution
International Scholastic Journal of Science, 2015 A basketball was released from varying drop heights to simulate the impact speeds of a typical soft, medium, and hard dribble. This was repeated across four different surfaces that students typically play on–exposed aggregate concrete, maple wood ...

Coefficient of Restitution of Badminton Smashes
International Scholastic Journal of Science, 2019 Badminton smashes were recorded and analyzed at high speed, measuring the velocities of the shuttlecock and racquet head to determine the relationship between initial impact velocity and the coefficient of restitution. It was found that the coefficient

Coefficient of Restitution of a Squash Ball
International Scholastic Journal of Science, 2019 The coefficient of restitution of a Double Yellow Dot squash ball was examined at impact velocities ranging from 13 to 29 m/s. A high-speed camera was used with video analysis to record and analyze the motion of a squash ball as it collided against a ...

Coefficient of Restitution of a Tennis Ball
International Scholastic Journal of Science, 2007 The coefficient of restitution (COR) of a tennis ball was investigated over a range of impact velocities. It was found that the COR of the ball was lower than ATP regulations specify, and that the COR decreased with increasing impact velocity.

Coefficient of restitution for wet particles [PDF]
Physical Review E, 2012 The influence of a wetting liquid on the coefficient of restitution (COR) is investigated experimentally by tracing freely falling particles bouncing on a wet surface. The dependence of the COR on the impact velocity and various properties of the particle and the wetting liquid is presented and discussed in terms of dimensionless numbers that ...

Interval of restitution coefficient for chattering in impact damper
Journal of Low Frequency Noise, Vibration and Active Control, 2022 Based on the impact damper, a dynamic model of a non-fixed constrained collision system was established. The coefficient of restitution is used as the main control parameter to analyze the system’s periodic movement and its bifurcation region.
