How is work calculated?Answer:

Work and Power
List 2 ways work can be done on an object.Answer:
What is power and how is it calculated? Answer:

Answer 1

Power is the rate at which work is done or energy is transferred. It is calculated by dividing the work done or energy transferred by the time taken to do it. The formula for power is P = W/t, where P is power, W is work done, and t is time.
