Forces... and how they affect Us.

Newtons Law of Inertia (First Law)

  • An object at rest will remain at rest, whereas an object in motion will remain in motion unless an unbalanced force (Inertia) acts upon it.
  • This law states that unless a force acts upon an object it will stay at rest or motionless but if said object is in motion it will only stop or slow down if Inertia (the resistance) acts upon it.


  • Inertia is the resistance of any physical object towards any change in its state of motion (Velocity)
  • For instance inertia would be a star's gravitational pull that stops a... ball or Rocket from continuously floating throughout space in a straight line (In a Constant Velocity).
