I put out a tablecloth and put dishes on top of it. I then grabbed the tablecoth and pulled it down and off the table. This left the dishes in place on the table. the dishes have a lot of mass so they stay in place, which is inertia.
MY FAMILY MEMBER'S EXPLANATION:
When Adam placed plates on a thin table cloth and pulled quickly, the plates stayed in place and did not move. The table cloth moved because it was in motion. The plates stayed at rest because they started in a rest state.
MY CRITIQUE:
It was pretty good about describing inertia and what it did in terms of the tablecoth and plates.
