Inertia: Penny Passengers
Roll the car so it runs into a thin book or piece of corrugated cardboard.
Do different coins respond differently? Dimes are lighter than pennies, quarters are heavier.
You need to push the car very gently, or you'll observe a different form of inertia - the car will move out from underneath the penny and the penny will drop to the table.
