1. What is the earliest archaeological evidence?Mid-4th millennium BCE in Mesopotamia
2. What is the initial wheel construction?Solid wooden discs, often assembled from multiple planks
3. Why did people use carts in ancient times?People used carts to move heavy things like food and building materials more easily. Carts made it faster and less tiring to carry big loads over land.
4. How do carts roll instead of slide?When you push or pull a cart, the wheels turn around the axle. This rotation keeps the wheel in contact with the ground while moving forward, which reduces the friction that would happen if the load were dragged.

Mesopotamia: An ancient civilization located in the Fertile Crescent, credited with early innovations including the wheel.
Axle: A rod or spindle passing through the center of a wheel or group of wheels, allowing them to rotate.
Friction: The force resisting the relative motion of solid surfaces, fluid layers, and solid elements sliding against each other.
Torque: A twisting force that tends to cause rotation.
