How many Watts of power are required for you to lift a 1 kg mass to a height of 1 meter i a time of 1 second?

Answer 1

To lift a 1 kg mass to a height of 1 meter in 1 second, you need to calculate the work done, which is equal to the gravitational potential energy gained. This is given by the formula ( \text{Work} = mgh ), where ( m = 1 , \text{kg} ), ( g \approx 9.81 , \text{m/s}^2 ), and ( h = 1 , \text{m} ). Thus, the work done is ( 1 \times 9.81 \times 1 = 9.81 , \text{Joules} ). Power is work done over time, so ( \text{Power} = \frac{9.81 , \text{J}}{1 , \text{s}} = 9.81 , \text{Watts} ).
