What kind of gear do I need for a battery driven wooden toy car? (roughly 1:32 scale)

[Derpitron]

My friends and I made a wooden toy car for a project. For now it's hand driven, but we want to add a battery and DC motor in order to drive it with a button.

We're not sure what material or size of gear we should choose for the "link" between the DC motor and the axle that rotates the car. We're not sure of the proper terms to search either, as we don't have any mechanical engineering knowledge. All we know is, the distance between two adjacent tips of teeth of the gear should be ~0.5cm. This is called the pitch of the gear apparently?

How should we figure out what gear to use/buy?

Would greatly appreciate any help or pointers. Thanks!

Well first you need to know, calculate or guesstimate speed of the two axles,torque and power of the system. Then how much space you have for the gears.

"Wooden toy" can be anything from about 2 inches long to 3 feet or more.. Is it intended to have people in it? Or kids?

You can probably use a plastic gear for a relatively small car.

As little inch pointed out please give a sketch of size of the toy car and it's weight. And load. As stated empty or occupied.
Intended use, high rpm or low rpm.
Torque vs speed. Is to be used in a flat level parking lot or semi rough terrain. The more description the the better.

Check with a local hobby shop that sells electric model cars. They can see the size and weight of the car and what space is available and supply you with the majority of the components, if not all of them.

We don't need particularly high torque or speed. Something that can be driven by a 5 Volt DC motor. To be intended to be driven on a cement and/or marble tile floor.
Overall weight of the car, without any battery components, is around 500 grams. No occupants at all.
Size is ~1 foot length, 0.3 foot breadth, 0.2 foot height.

The source of the project is from this video But the schematic linked in it's description is error 404ing and doesn't seem to show up on the Wayback machine. Our faculty don't seem to have the schematics either:

I'll ask some local hardware shops for any gears they might have and see those would work. Would metallic gears cause any chafing/erode the wooden gears?
