The definition of inertia is when an object remains still or moves in a constant direction at a constant speed. Inertia will continue unless the object meets some external force. The more inertia an object has, the less the object will change its motion when it meets another force. The ground is the force, the motion, that causes the object to no longer have inertia and to instead stray from its speed and direction.
