Identify and explain the factors that
affect potential and kinetic energy
(S8FE-Id-22)
- Ability to do work
- Expressed in Joules
- Light, heat, chemical or mechanical energy

 Potential Energy
 Kinetic Energy
Mechanical Energy
 Comes form the Greek word “Kinetikos” which means to move
 Energy in motion
Kinetic Energy
𝐾𝐸 =
1

𝑚𝑣2
KE = Kinetic Energy
m = mass
v = velocity
1. A swimmer has an average velocity of 1.2 m/s. If the mass of the
swimmer is 60 Kg. What is his Kinetic energy?.
Let’s try this one
Given: m = 60kg v = 1.2 m/s
Formula: 𝐾𝐸 =

𝑚𝑣2
Solution: KE =

1. Calculate the energy of a moving object which has a mass of 5 kg and a
velocity of 2 m/s.
Let’s try this one
Given: m = 5kg v = 2 m/s
Formula: 𝐾𝐸 =
1

 Stored energy as a result of deformation
of an elastic object
Elastic Potential Energy
 Stored energy of an object at rest
Potential Energy
 Stored energy of a body or an object in
respect to its position and point of
reference.
Gravitational Potential Energy
𝐺𝑃𝐸 = 𝑚𝑔ℎ
GPE = Gravitaitonal Potential Energy
m = mass
g = acceleration due to gravity
h = height
Gravitational Potential Energy
1. If a light bulb is elevated at 1.2 m from the ground and has a mass of
0.25 kg, what is the potential energy of the bulb?
Let’s try this one
Given: m = 0.25 kg h = 1.2 m g = 9.8 m/s2
Formula: GPE = mgh
Solution: GPE = (0.25 kg) (9.8 m/s2) (1.2m)
= 2.94 kg m2/s2
= 2.94 J
1. Calculate the GPE of an object hanged at 3 m above the ground whose
mass is 2 kg
Let’s try this one
Given: m = 2kg h = 3 m g = 9.8 m/s2
Formula: GPE = mgh
Solution: GPE = (2kg) (9.8 m/s2) (3m)
= 58.8 kg m2/s2
= 58.8 J
