1. ENERGY and MATTER Make up our universe MATTER
has mass and occupies space
we can see it
is a substance
Energy
Is the mover of a substance
has ability to do work or cause change
process and a “thing” a verb and a noun
can transform from one form to another
Can transfer from one object to another
is mostly not visible

2. CONSERVATION OF ENERGY
Energy CANNOT be created or destroyed only transferred from one form to another, total energy DOES NOT change

3. 2 Types of Mechanical Energy
Mechanical means pertaining to the laws of motion
1- Potential Energy
- Energy stored and held in readiness
- Has the potential to do work
2- Kinetic Energy (gravitational)
- Energy of motion
A yo-yo has
kinetic energy
when moving
- Does work through motion

4. PE = mgh Gravitational Potential Energy
Energy cont.
Gravitational Potential Energy
-Potential energy due to elevated position
- Work is done to elevate object against earth’s gravity
Gravitational potential energy =
mass * gravitational acceleration * height
PE = mgh
Where mass= m, g=gravitational acceleration, and h= height

5. POTENTIAL E TYPES- stored E
Mechanical- E due to position
(a spring)
Nuclear- E locked in nucleus of
an atom (splitting of atoms called fission)
Chemical- E stored in food, coal etc.
Gravitational- E stored due to gravity
(a dam)

6. What are some examples?

7. KE = m * v² 2 Kinetic Energy Kinetic energy = mass * velocity² 2
- Depends on the objects mass and speed
- Not just speed but speed multiplied by itself or squared
- Small changes in speed produce large changes in kinetic energy
Kinetic energy = mass * velocity² 2
KE = m * v² 2

8. KINETIC E TYPES Movement- E created due to motion
Electrical- E due to movement of
electrons
Radiant- E emitted by electromagnetic waves (radio, x-rays)
-Thermal- E created by heat and internal movement of atoms

9. What are some examples of this?

10. Energy Illustrations -Fold a blank sheet of paper into four sections
-Illustrate the 7 types of energy (4 on front 3 on back)
-Each section must :
- Illustrate an EXAMPLE (not mine) of each E type
- Define the energy type
- Write example into a sentence
