What Do Power and Torque Represent?

[Elrond]

Power and torque refer to: 1. For internal combustion engines, power represents the amount of energy generated by fuel per unit time. Power is merely a physical quantity describing the speed of work—the higher the power, the more energy is generated per unit time, often resulting in a higher top speed for the vehicle; 2. Torque, in the context of engines, is defined as the force output at the crankshaft end. The magnitude of torque determines the vehicle's acceleration, making torque a physical quantity that measures the engine's acceleration capability. The relationship between power and torque is that power is the product of a constant n, torque, and rotational speed. Torque and rotational speed are inversely proportional—when torque reaches its peak, further increasing the rotational speed will cause it to drop sharply.
