THIS PAGE WILL BE GONE IN 5 mins BE SURE TO HAVE YOUR ID VISIBLE AROUND YOUR NECK, NO NON- POLY ATTIRE! DRILL: an angleDate: Jan 25, 2012 A 500 N force is applied at an angle of 15o to the horizontal to move a 25 kg object at a constant speed for a horizontal distance of 10 m WHAT IS THE WORK DONE? OBJECTIVE Define and solve word problems on power. HOMEWORK Copy and answer no & of page 278 no of page 281 [ you have 4 days! ] no of page 281 [ you have 4 days! ]

THINK ABOUT! Who does more work a person A pushing an object 5 m with a force of 10 N in 2 seconds or a person B pushing an object 2.5 m with a force of 20 N in a second? Who will you ask to help you do work? Why?

3 What is POWER? Power is the rate at which work is done. It is the work/time ratio.

What is the UNIT OF POWER? Watt is equivalent to a Joule/sec
