• You have no safety mat or adhesive stickers to allow for purchase on a surface with a low coefficient of static friction.
  فأنت لا تستخدمين سجادة و لا ملصقات متماسكة لحمايتك و أنت تقفين على سطح ذي معامل منخفض للاحتكاك الساكن
• The correct answer is "when covered by a film of liquid sufficient to reduce the coefficient of static friction between the tire and the road to essentially zero, but not so deep as to introduce a new source of friction. "
  الإجابة الصحيحية هي "عندما تتغطى بـ غشاء من سائل كاف ليقلل مُعامل الإحتكاك السكونيّ

• Coefficient of friction is a dimensionless number representing the ratio of the friction force to normal force. Coefficient of friction can vary significantly depending upon the materials tested and whether a lubricant has been used.
