====== List of Common Misconceptions ====== - People sometimes think forces pairs cancel resulting in no motion. - People sometimes forget the Newton's third law also applies to gravity. - People often mistake the coefficient of friction μ for the frictional force. - Tension ($T$) **__does not__** equal the weight of the falling object (typically $W_2$) in a [[physics:pully_problems|pully system]], the rope redirects the weight.
