Inertia Investigation

I see inertia when you have a cup, a coin and a index card and you try to get the coin in the cup by moving the index card. Also when you are running and you drop a ball and try to make it land on the x while running. Also when you have 5 poker chips and hit the bottom one and see what happens. One example of things that don't stop moving are clouds because there is nothing in the air to really stop them. One example of one thing moving and the other staying still is when you have two cars and they push in to each other because one car has a larger force and there is more mass on that one car.
