braking force; braking power
Technical term used in automotive, railway, and mechanical engineering contexts to describe the force that slows or stops a vehicle or machine.
This car has strong braking force, so it's reassuring even on steep slopes.
To calculate the braking force of a railway vehicle, you need to consider the friction coefficient.
制動 is the act of braking or the braking mechanism; 制動力 specifically quantifies the force involved.
Compound of 制動 (braking) + 力 (force). A straightforward technical coinage.
