This document discusses potential, kinetic, and total energy. It defines potential energy as stored energy using the equation PE = (m) (g) (h), where m is mass, g is gravitational acceleration, and h is height. Kinetic energy is defined as the energy of motion using the equation KE = 1/2 mv^2, where m is mass and v is velocity. Sample problems are provided to calculate the potential energy of a book lifted 0.5 m and the kinetic energy of a 150 kg object moving at 15 m/s. Exercises at the end ask the reader to calculate the kinetic energy of 100 kg and 250 kg objects moving at 12 m/s and 15 m/s, respectively, using

ENERGY
DIRECTION: Fill in the blanks with the letters that complete the
word. Use the given clues.
1. E _ N _ _ G _ - is the ability to do work.
2. P _ _ E N _ I _ _ L E _ N _ _ G _
- is the stored energy.
3. _ I N _ _ I C E _ N _ _ G _
- is the energy in motion.

3. Potential Energy- is the stored energy
PE = (m) (Ag)(h) where
m – is the mass of the object,
Ag – is the acceleration due to gravity of 9.8
m/s2
h – is the height that the object reached
Sample Problem:
A 1.0 kg book is lifted to a 0.5 m above the table, what
would be the potential energy of the book?

4. Kinetic Energy – is the energy in motion
Equation/ Formula
KE = ½ mv2 where m is the mass of the object,
V is the velocity of the object
Sample Problem:
What is the Kinetic Energy of a 150 kg object that is
moving with a speed of 15 m/s?

5. Exercises
Use the GRESA Method in solving Kinetic Energy Problem.
1. What is the Kinetic Energy of a 100kg object that is moving
with a speed of 12 m/s?
2. What is the Kinetic Energy of a 250 kg object that is moving
with a speed of 15 m/s?
