### p=mv

Is the work function interhchangeable with power?

I think when you say power you mean momentum and p=mv stands for momentum=mass times velocity. The work function is the energy required to eject an electron from a metal surface so it is not interchangeable with momentum (momentum is different from energy, which is in joules).

Yeah I believe the equation for power is force x velocity
