are there three situations where people need a low coefficient of kinetic friction and 3 situations where you might need a high coefficient of kinetic friciton? thnx!
would the force of gravity also double? and what about when the force of gravity triples, then what would happen to the force of friction? Would it be the same down the road, like for example, when it quadruaples, would the force of friction also quadruaples..and have a direct relationship btw...
