Final answer:
The object with the most inertia among the given choices is the 20 kg goat because inertia is directly related to the mass of an object, and the goat has the highest mass.
Step-by-step explanation:
The concept in question here is inertia, which is a property of matter that quantifies an object's resistance to changes in its motion. Inertia is directly related to the mass of an object. Among the given options, the object with the most inertia is the one with the greatest mass. Therefore, to determine which object has the most inertia, we simply compare their masses.
Given the options:
- a) 6 kg box of Chex mix
- b) 14 kg dog
- c) 5 kg cat
- d) 20 kg goat
Out of these options, the object with most inertia is:
d) The 20 kg goat.
Mass is the best property to quantify an object's inertia, as stated in the physics texts. Greater mass means greater inertia, which means an object with greater mass will resist changes to its motion more than objects with less mass.
