In rotation, force becomes torque, mass becomes moment of inertia, and acceleration becomes angular acceleration.

在旋转时，力变成力矩，质量变成转动惯量，加速度变成角加速度。

Torque divided by moment of inertia is what will cause the angular acceleration, namely the derivative of angular velocity.

扭矩除以转动惯量,就会引起角加速度，也就是角速度的导数。

So, even though no actual gears are being changed, using the paddle-shift modulates the torque to provide the jolts of acceleration and deceleration that would happen if there were a real gearbox.

因此，尽管事实上没有变动齿轮，使用可调节滑杆调节扭矩以提供加速和减速时的震动，就像有个真实的变速箱似的。

Its cutting-edge technology ensures that the B-Class Electric Drive is not only sustainable (because it offers local emission-free driving) and agile (because of its high torque and acceleration), but also fully networked.

The hybrid powertrain will generate a combined equivalent of 245 horsepower and 345 pound-feet of torque, which ensures strong acceleration.

So, even though no actual gears are being changed, using the paddle-shift modulates the torque to provide the jolts of acceleration and deceleration that would happen if there were a real gearbox.
