I cannot imagine P=F v cosa alhough I know its mathematical derivation.(adsbygoogle = window.adsbygoogle || []).push({});

Think a car speeding up from 0 to 30. It cannot have the same acceleration when it continues to 60 km/h. It seems nonsense.

Can you help me understand this better?

Any help is appreciated.
