• newton's first law:

  • an object remains in same state of motion unless acted on by a resultant force
  • if resultant force is zero:
  • stationary object stays stationary
  • moving object continues to move at same velocity
• • inertia is tendency of object to continue in its current state at rest or in uniform motion
• • if the resultant force is not zero, the object will accelerate or decelerate
