Question

What is Newton’s first law?
 

  1. F = ma    
  2. Every action has an equal and opposite reaction    
  3. An object at rest stays at rest, an object in motion stays in motion.    
  4. An object in motion comes to rest, an object at rest starts in motion even if no external force is applied    

hintHint:

An object will remain in rest or constant uniform motion in straight line unless compelled by an external force

The correct answer is: An object at rest stays at rest, an object in motion stays in motion.


    Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
