Question

If work is constant, power increases as time increases. a. True b. False

Answer 1

Answer:

False.

Explanation:

Power may be defined as the rate of doing work with time. The S.I. unit of power is J/s or watt. The power is a scalar quantity as it has only magnitude and no direction.

The power can be calculated by the formula:

Power =  work done/ time taken.

From the formula, it is clear that power is inversely proportional to the time taken by the body. Hence, if the work remains constant, power will decrease with time.

Thus, the answer is false.
