Why does friction increase as speed increases?
explain using the big idea of particles

According to the particle theory, the third theory is that if heated,the particles move faster and then the kinetic energy increases.I think your question relates to fluid friction and it will only increase when an object increases in which will cause it to come intact with more particles.The faster the object moves- The more particles.The greater the attraction between particles or molecules, then the greater the resistance of the molecules to flow past one another.Hope that helped !

A) acceleration. this seems to be the one that makes sense.
