Inertia
Inertia is the resistance of any object due to changes in its motion or direction. [1] There are effectively two types of inertia— mass, which is how much of an object exists (often measured in units like kilograms) and rotational inertia. Objects with high mass have more inertia, which means that more energy is associated with their motion.
