After learning about friction we expect you to be able to:
  • Identify the direction that friction is acting.
  • Identify which object(s) are creating a force of friction.
  • Determine which normal force is associated with a particular force of friction.
  • Decide if a friction is static or kinetic.
  • Determine if static friction is equal to or less than the maximum static friction.
  • Friction max is only equal to the coefficient of static friction times the normal force when the static friction is the greatest it can be without slipping. Otherwise it is equal to whatever is required to keep the surfaces from slipping.
  • Know when static or kinetic friction is to be used
