Expert Answer:

  • Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion at a constant velocity, unless  an unbalanced force acts upon it. 
  • This law of motion is also known as the law of inertia, where inertia is the resistance to change in motion.
  • eg. A rolling sphere will remain to roll over a plane unless the external unbalanced force stops it. i.e in this case, the frictional force.
