To build upon your thoughts, here's an excerpt from a basic physics text:
"An object's inertia is determined by its mass. According to Newton's second law, a force acting on an object is equal to the mass of the object multiplied by the speed of motion the object undergoes. Thus, if a force causes an object to speed or travel at a certain rate, then a stronger force must be applied to make a more massive or larger object travel at the same rate; the bigger object has a larger amount of inertia that must be overcome. For example, if a bowling ball and a baseball are moving so that they end up rolling at the same speed, then a larger force must have been applied to the bowling ball, since it has more inertia."
