Particle Collision Study Based on a Rotational Boundary Condition
Journal of Marine Science and Engineering, 2023 The main engineering machinery for the hydrodynamic lifting of seafloor mineral particles is rotor machinery with rotating impeller motion. It is important to study the rebound mechanism of collisions between particles and rotating walls to improve the ...

Coefficient of restitution for viscoelastic disks [PDF]
Physical Review E, 2007 The dissipative collision of two identical viscoelastic disks is studied. By using a known law for the elastic part of the interaction force and the viscoelastic damping model an analytical solution for the coefficient of restitution shall be given. The coefficient of restitution depends significantly on the impact velocity. It approaches one for small

Watching and listening to the coefficient of restitution
The Physics Teacher, 2011 Abstract We discuss the measurement of the coefficient of restitution (COR) and the acceleration of gravity g using video and sound analysis with both Tracker and Logger Pro 3 software. Measuring COR of a bouncing ball is a common activity in physics labs from high school to intro level college courses (e.g., measuring COR to obtain gravitational ...

The Effect of the Width of an Aluminum Plate on a Bouncing Steel Ball [PDF]
International Scholastic Journal of Science, 2013 The effect of the distance between clamping supports of an aluminum alloy plate on the coefficient of restitution of a bouncing steel ball was investigated. The plate was supported on two wooden blocks with a meter stick secured on either side.

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...
