Inertia: Penny Passengers

Place a penny on top of a small toy car.

Roll the car so it runs into a thin book or piece of corrugated cardboard.

Observe the car and the penny.  What can you learn from this activity about the importance of seat belts?

What difference does a seat belt make?  Try again, using a small piece of tape to hold the penny on the car.   

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.
