TITLE CARD

Work as we know is the activity wherein we spend our time to get a penny like managing a business, going to the farm, and the like. In the world of science, dealing with work does not guarantee you to have the penny you are aiming for instead we are to give meaning to that word. Scientifically speaking work is a direct relationship of what we call magnitude and force. Moreover, in dealing with work in this SIM we would be focusing on this two variables plus another three variable for us to see the differences of work.

On the other hand, we always deal of work in our every day life. Walking in the hallway and the stairs is an example of working thus work as stated above does not necessarily deal in having money to spend.

GUIDE CARD

OBJECTIVES: After reading this SIM the student should be able to:

1. Use the formula of work in solving problems related to work.

2. Distinguish the difference of the two kind of work and use their proper formula.

3. Define what is work in horizontal and work in vertical.

CAN I EXPECT YOU?

This SIM covers lessons about

work and was

summarized thus you can

master it in just a

little span of

time

GUIDE CARDWhat I need to know

WORK (horizontal)-Generally defined as Force multiplied to magnitude.-Work is defined as the force (F) multiplied by the displacement (d).

Fig.1: W=Fd F

-applicable only to horizontal type of works.- Applied by pushing or pulling an object parallel to the ground.

BEAR IN

MINDWORK is expressed in JOULES (J)

FORCE is expressed in NEWTON (N)

DISTANCE is expressed in METER (m)

Activity Card 1WANT TO HAVE A WORK

HERE IS SOMETHING FOR YOU! Solve for the answer in each problem.1.A man throw a ball with a force of 10 N to a wall 8 meters away. What would be the work done by the man?

2. If the man is 10 meters away from the wall and it exerted a work of 100 joules, what would be the force the man had exerted?

*direct substitution*force is directly

proportional to work

and inversely to displaceme

GUIDE CARDWhat I need to know

WORK (vertical)-in case the work to be done is lifting or putting down an object.

h

-applicable to vertical kind of work.

W=Weight(height) = mgh

Where: m=mass of object g=gravity due to acceleration h=height

CONSIDER ME.

Acceleration due to gravity (g) is a constant with a value of 9.8 m/s^2MASS is expressed in kg (g)HEIGHT is expressed in meter (m)

Activity Card 2WANT TO HAVE A WORK AGAIN !

HERE WE ARE AGAIN! Solve for the answer in each problem.1. A 2 kg-object is lifted to a height of 5 meters, how much work was done?

2. If a book 6 meters from the ground exerts 50 joules of work. What is the mass of the book?

*direct substitution.

TIPS

*mass is directly

proportional to work

and inversely

with height and the

acceleration due to gravity.

QOUTE

Enrichment CardWeight Me NOW!! :D

Describe the work done by each image if it is small or big.50 joules would be the midline, so if the work exceeds 50 J then is big.

Image small big

1. h=12 m= 4

2. F=9 d=4

3. h=2 m=2

4. F=4 m=7

*WORK INCREASE AS FORCE INCREASE*WORK INCREASE AS THE HIEGHT INCREASE

REFERENCE CARDTAKE ONE LAST

LOOK!*WORK is generally defined as Force multiplied by Distance which also is used for horizontal works.

W=Fd *VERTICAL WORK is Mass X Gravity due to Acceleration X Height

W=mgh N (newton) Kg*m/s^2

J (Joules) N*m
