How would a car made out of paper and film caps exhibit inertia at rest?
Hmm… asked:
I have no idea what the answer to this would be. Inertia is restistence to change in motion, but I don’t understand how my small car made out of index cards and film caps for wheels would exhibit this.

Inertia: Without outside forces, a body at rest remains at rest, while a body at motion remains in motion.
This applies whether referring to a piece of tissue, or a huge rock.

Inertia could be demonstrated by putting the car on a sheet of paper and then yanking the paper away. The car will move some, but slides some and doesn’t keep up with the paper. If its wheels were sliding frictionlessly on the paper it wouldn’t move at all. It slides because staying with the accelerating paper would require a force (due to its mass and the rotational inertia of the wheels) that is larger than the friction force.
