What characteristic of sports surfaces relates to the viscoelastic behaviour of most surfaces for sport and exercise, where the viscous stresses are dissipated as heat, not returned to the striking object?

Question

Quizplus · Accepted Answer

Resilience in sports surfaces refers to their ability to absorb energy from impacts (such as footsteps or ball bounces) and then release some of that energy back. However, in the context of viscoelastic behavior, not all of the absorbed energy is returned to the striking object; some of it is dissipated as heat. This characteristic is directly related to the surface's resilience, as it describes how effectively a surface can return energy to the object, with the understanding that viscoelastic materials inherently lose some energy as heat rather than returning it all.
