When work is measured in joules and time is measured in seconds, power is measured in
2 answers:
Answer:
Watts
Explanation:
Work done of an object is given by the product of force and displacement i.e.
W = F.d
Where
F = force
d = displacement
The SI unit of work done is joules. It is defined as the amount of energy used or exerted when a force of 1 newton is applied over a distance of 1 meter.
Power output is defined as "work done per unit time". Mathematically, it is given by :
The SI unit of power is watts. It is defined as the "amount of energy used when 1 joule of work is done per unit time".
Hence, power is measured in watts.
