d. Appreciate

D. Discussing the “Energy is the measure of the capacity of an object to
new concepts do work.”
and practicing
new skills #1 “Do you believe that if we eat more we can also do
more?” “Yes Mam”

“More energy means more work can be done. Energy

also comes in different forms such as light, sound,
chemical, heat, and mechanical energy.”

“Mechanical energy is the energy of a particle due to (Students are

its motion and its position.” listening while the
teacher is
“There are two types of mechanical energy, kinetic discussing.)
and potential energy.

 Kinetic energy is the energy of bodies in

motion.
There are two factors that affect kinetic energy these
are:
 Mass
 Velocity

𝐾𝐸 =m(v2)/ 2
The equation for kinetic energy is:

- Kinetic energy is of an object is directly proportional

to the mass and to the square of its velocity.

“If you double the mass, the KE is also doubled.”

“If you double the velocity, the KE will be increased

4x.”

 Potential energy is a stored energy having

potential to do mechanical work. Potential
energy is the energy possessed by bodies at
rest.
- Gravitational Potential energy- is a stored
energy due to its relative position from the
center of the Earth. For example, a book on top
of the table, car parked on a ramp.
o The gravitational potential energy of an
object is determined by this equation:

o 𝐺𝑃𝐸 = 𝑚𝑔ℎ

o m- is the mass of the object.

o g- is acceleration due to gravity
(9.8𝑚/𝑠2)
o h- is the height or elevation of the object.

“Now we were going to have our activity named as:”

ACTIVITY 1: LET’S CLASSIFY IT

Direction: Complete the table by classifying the given

descriptions as Kinetic or Potential energy. Write the
number associated with each type of energy.

E. Discussing the Study the picture below:

new concepts
and practicing
new skills #2

“Let us now examine what will happen to the

mechanical energy of a roller coaster.”

“If cart moves from positions H to O, the potential (Students are

energy decreases since its height decreases. On the listening while the
other hand, its speed increases as it moves down, teacher is
thus its kinetic energy increases. From point O to P, it discussing.)
gains back its potential energy since it is moving up at
a higher elevation. In contrast, its kinetic energy
decreases as it moves up because it slows down. This
exchange of potential and kinetic energy is known as
mechanical energy.”

“Well, at the top of the hill, the cart is motionless, so

as the cart begins to move down the hill, the potential
energy begins to be converted to kinetic energy. The
car gathers speed until it reaches back on top of the
other side of the hill and converts the gained kinetic
energy back to potential energy.”

“Let’s have another activity, this time I named it as:”

knowledge you bought is a bluff the points will be
given to the other groups. In addition to that, I will be
also getting your products. The good news is if it is a
fact, all the points will be given to your group.
