Counterclockwise or Anticlockwise Rotation

Throughout this book we have used the terms clockwise and counterclockwise to describe a specific direction of circular motion. Although the circular or rotational motion indicated by the term clockwise is a two-dimensional (planar) concept, when you add the observer, it becomes a three-dimensional asymmetric

Many items in our lives contain objects that need to be tinned with our hands. Right-handed human beings find it easier to turn many things clockwise rather than counterclockwise, especially when force must be applied at the same time.
