REVIEW
• CABBAGE RELAY (made of paper). The teacher will pass the
cabbage with music and once the music stops, he/she will read the
question and answer(piece of papers with question regarding the
review on the laws of motions and its principles and examples.
Whoever answer the questions will received points or badge
stickers.
• Recall on the Newton’s Laws of Motion.
• 1. Law of Inertia
• 2, Law of Acceleration.
• 3. Law of Interaction.

OBJECTIVES
1. Analyze the video about Potential Energy.
2. Realize how the sample situations applied
potential energy.
3. Value the importance of the lesson in
every day situations.

GROUP 1
Which ball will come down with
more energy, the ball from a
height of 5 meters or to a 10
meter height slide?
GROUP 2
A 10 tons rock or a stone
lying on top of the hill and it
falls.
GROUP 3
If we cut the 10
meters rope with a
16 kilograms weight

catapult/ sling shot is
stretched to a one half

GROUP 1
Which ball will come down with
more energy, the ball from a
lower height or to a higher
height?
•BLUE BALL has more energy due to
more height’
•Energy possessed by an object due
to its position.
•THE HIGHER THE POSITION OF AN
OBJECT DUE TO ITS HIGHER
POSITION FROM THE GROUND.
GROUP 2
A rock or a stone lying on top
of the hill and it falls.
• * When this rock is pushed off the
hill, it falls with a great speed due
to its higher position from the
ground and have a great
• speed due to its potential energy.
GROUP 3
If we cut the rope
with a heavy
weight
•If we cut the rope, the weight will come
down with a great energy because it has a
lot of potential energy due to its height
and weight.
•Potential energy of a body depends upon
the mass of the body and change in its
position from the ground level.
GROUP 4
When the rubber of
the catapult/ sling
shot is stretched.
•THE HEAVIER THE OBJECT, THE
MORE THE POTENTIAL ENERGY.
•THE HIGHER THE OBJECT, THE
MORE THE POTENTIAL ENERGY.
GROUP 5
Stretch position of
bow and arrow.
•Due to its stretch position, a lot if
potential energy is there
•The more it is stretched, the more
potential energy it will store.
•With more force, the arrow will go
ahead.
•Potential Energy- the
energy which is stored
in a object or a body
due to its position
configuration of parts.
• -energy possessed
by an object due to its
positions.
•The formula in solving for the
potential energy is
• P.E. -mgh
•Where :
• P. E. = potential energy
• m=mass
• g= acceleration due to
gravity of 9.8m/s2
• h= height
•In MAPEH, before diving into the
water, swimmers always stand on
the diving board and stretch.While
standing they have some amount
of gravitational potential energy.
•In ARALING PANLIPUNAN,
water forms in the Philippines
like water falls. Water at the top
of a very high water fall
possesses gravitational
potential energy.
•In TLE, thermal energy is used to
cook food, Thermal energy is heat.
Its converted from either electrical
potential energy or chemical
potential energy, depending on
the cooking appliance.
• Potential Energy- the energy which is stored in a object or a body
due to its position configuration of parts.
• -energy possessed by an object due to its positions.
• -the formula in solving for the potentian energy is
• P.E. -mgh
• Where :
• P. E. = potential energy
• m=mass
• g= acceleration due to gravity of 9.8m/s2
h= height
ASSIGNMENT :
• Answer the following questions:
• How is potential energy applied to the following scenarios:
• 1. Which ball will come down with more energy, the ball from a height of 5
meters or to a 10 meters height?
• 2. 10 tons of rock or a stone lying on top of the hill and it falls.
• 3. Water stored up in the dam or tanks on the top of the buildings.
• 4. If we cut the 9 meters rope with a 15 kg weight.
• 5. When the rubber of the catapult/ sling shot is stretched,
• 6. Stretch position of bow and arrow
• 7. Why does the water released from a dam has a huge energy to produce
electricity.
