If thrust is such as to exactly cancel gravity, it is F = m g so the acceleration with no gravity would be g. In your question, however, you mention power instead of thrust. WebMathematically, it is computed using the following equation. Power = Work / time or P = W / t The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second. how to buy a house out of state and move
