John is trying to change the position of the bed in his room. He tried to push the bed, but he couldn't. He thinks it's hard to push the bed because it is big. Why do you think it's hard for him to push it?
(Your answer should have the words: Ine... and Ma... in it)
It is hard for john to push the bed because the bed has high inertia because of its high mass.
