Hello, I’ve been thinking about the sizes of torque and power when driving a car and I’ve read a few things about it. I’ve often read that the power is decisive for the acceleration. But if I think now that the angle acceleration on the crankshaft is directly proportional to the torque of the engine, what role should the power play? I’d like to have a clear picture of how the current power and the current rotation-mom My ideas: I know that power and torque are not independent of each other, but are related to the speed. If I now think about what makes the acceleration when driving, I think of two arguments: 1) The acceleration is proportional to the angular acceleration of the crankshaft. This in turn is proportional to the adjacent torque -> thus determined the torque the acceleration. 2) To accelerate a car kinetic energy must be transferred. The current power of the engine indicates how much energy per time it transfers to the car. -> so the power determines the acceleration. Which of the statements is correct? Is it at all one or can you unite both somehow?
