Now, based on my understanding; if a ball hits another object with enough force and acceleration; and the other object is resistant enough, the ball will bounce. However, is there any instance where a ball will never bounce?
I know this may be a stupid question, but it got me thinking how we uneducate folks often assume something to be true, without even a basic understanding of how that something actually works.
I studied this in physics last year but forgot the name of the property. Pretty much all objects have a property that determines how elastic a collision is. A rubber ball's value might be close to 1 meaning that the collision is close to elastic against e.g. a wall. Another object like a ball made of plasticine might have a value of .1 or not even which means the collision is not elastic at all therefore a huge amount of kinetic energy gets lost i.e. it hardly bounces back.
