  • Friction depends on the nature of surfaces in contact.
  • The substances which reduce friction are called lubricants.
  • When one body rolls over the surface of another body, the resistance to its motion is called the rolling friction.
  • When one body slides over the surface of another body, the resistance to its motion is called the sliding friction.
