 solve the problem in getting pressure involving force and area.

II. LEARNING TASK
Topic: Pressure

Concepts:
Pressure is defined as the force F per unit area A, so??????=
F
??????

Pressure therefore has unit of N/m
2
= kg m¯
1
s¯
2
it is usually denoted P or p. Pressure
can be measured in atmosphere, bars, inches or mercury, millimeters of mercury,
Pascal or torr.
F is the force= N
A is the area in square= m
2
meter
P= Pressure= Pa
One N/m
2
is given a special name, Pascal (Pa), in honor of Blaise Pascal, who did
considerable studies on fluid pressure.

Post-Discussion Activity
The teacher will ask the students to give/cite some examples of
pressure they encounter in their life.

Analysis
TEACHER’S ACTIVITY STUDENT’S ACTIVITY
What is pressure?
What is the formula and unit for pressure?

What is the relationship between pressure
and area?
Pressure is the force per unit area.
??????=
F
??????
=
??????
m2
=????????????

Inversely proportional

5. Abstraction
How force and area affects pressure?
Give some examples showing the relationship of pressure to force and
area.

Application
All of us experience forces in our surroundings. Our bodies and the sea
of air around us interact. Air, a fluid, exerts a big force on us. Yet, this force does
not crush us because our bodies respond with an equal and opposite force.
IV. EVALUATION
Identify the terms being described.
1. It is defined as the force per unit area.
2. A person who is the pioneer work with pressure.
3. Force divided by area is the formula of ____.
4. It is perpendicular to the given area.
5. It is the unit of pressure.
Solve the problem

.

V. ASSIGNMENT
Solve the following problems
1. Suppose the force exerted by the air on one face of a cube is 8820N. Each side
of the cube measures 30cm. calculate the pressure on this face.
2. What will be the pressure if the force is equal to 80kg m/s
2
and area of 12cm

6. LESSON PLAN IN PHYSICS

I. OBJECTIVES
At the end of 60 minutes period, 75% of the students must be able to:
 define the term “fluid pressure”,
 understand the relationship of fluid pressure to density and height (deep);
and
 solve the problems involving the topic.

II. LEARNING TASK
Topic: Fluid Pressure

Concepts:
Water pressure used to describe the flow strength of water through pipe or
outer type of channel.
The pressure is the same in all direction in a fluid at a given point. This is true
because of the characteristic of liquids to take shape of their container.
Other effects of fluid pressure are motion, heating, and chemical effects, as well
as applications in the field of hydraulics and in aircraft. Fluid pressure from gravity is
the weight of the fluid above divided by the area it is pushing on. The pressure
under water increases with how deep you are. The equation for calculating pressure
is Pressure= D*g*h
Where D is the fluid’s density, g is the standard gravity (9.8m/s
2
) and h s the depth
of the object in the fluid.

Application
Fluid pressure is the reason that divers need to breathe air from tanks or high pressure
hoses when they dive beneath the surface area of the sea.
Evaluation
Write T if the statement is correct, and write F if the statement is wrong.
