gear ratio
Sprocket teeth comparison
A gear ratio is the relationship between the number of teeth on two meshing gears, determining how rotational speed and torque transfer between them.
A high gear ratio means more torque but less speed; a low ratio means more speed but less torque.
The concept extends to any system where mechanical advantage is calculated: The truck's gear ratio makes it better for towing than highway driving.
