I know this is a science term, but I need to fully understand what the physics term, "intertia". I belive it is where an object remains at rest or at a constant motion, unless a forces acts to change the motion. Let me know if I am right please. If I am not, can you explain in a simple way? Thanks!

"Inertia is the resistance of the object to any change in its motion, including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force."
