G. Finding practical applications of concepts and skills in daily living
Your opinion here!
If you were be given a chance to be the leader of the our country, how would you exercise your power of authority?
H. Making generalizations and abstractions about the lesson
Power provides a measure of both the amount of work done or the amount of energy expended and the time it takes to do it.
If you do a physical task quickly you have more power than when you do the same task slowly.
In science, power is defined as the rate at which work is done or the rate at which energy is expended, or is transferred, or transformed. In equation,
Power = work/time or
Power = energy/time
What is the SI unit of power? Since the SI unit of work is joule and the SI unit of time is second, the SI unit of power is Joule/second. This is given a special name,
watt, in honor of James Watt. So, 1 watt (W) = 1 joule (J)/second (s)
I. Evaluating Learning

3. A girl carries a heavy suitcase quickly up a flight of stairs. A
boy of the same weight carries the same suitcase slowly up the flight of stairs. Which statement is true?
A. The girl did less work and had less power than the boy.
B. The girl had less power than the boy.
C. The girl did more work and had more power than the boy.
*D. The girl had more power than the boy
4. What is the power develop by a jumbo jet that cruises at 200 m/s when the thrust of its engine is 100,000 N?
A. 20,000 W B. 200,000W C. 20,000,000W D. 2000 W
