Bounce is a term that refers to the action of an object rebounding off a surface after impact. This phenomenon occurs due to the elasticity of the object and the surface it hits. For example, a basketball will bounce when it strikes the ground, returning to a height determined by the energy lost during the impact. In physics, bounce is often discussed in relation to concepts like energy transfer and momentum. The degree of bounce can vary based on factors such as the material of the object, the surface it contacts, and the angle of impact. Understanding bounce is important in fields like sports, engineering, and material science.
