List Examples
What is Mechanical Energy?
o Energy due to a object’s motion (kinetic) or position (potential).
The bowling ball has mechanical energy.
When the ball strikes the pins, mechanical
energy is transferred to the pins!
Examples of Mechanical Energy
What is Electrical Energy?
o Energy caused by the movement of
electrons
Easily transported through power lines
(wires)and converted into other forms of
energy
What is Light Energy? o Light energy travels
in straight lines and can travel through
empty space!
Includes energy from gamma rays, x-rays,
ultraviolet rays, visible light, infrared rays,
microwave, and radio bands
What is Thermal Energy?
o Heat energy
o The heat energy of an object determines how
active its atoms are.
A hot object is one whose atoms and molecules are excited and
show rapid movement.
A cooler object's molecules and atoms will show less movement.
What is Sound Energy? o Sound energy is produced from
vibrations and requires a medium to travel
through.
Vibrating molecules (atoms) strike or bump
into other molecules.
o Sound travels best through a solid and worst through a gas.
QUIZ TIME! Electrical energy is transported to your house through power lines.
When you plug an electric fan to a power outlet, electrical energy is transformed into what type of energy?
MECHANICAL ENERGY
QUIZ TIME!
What energy transformation occurs when an electric lamp is
turned on?
ELECTRICAL ENERGY
LIGHT ENERGY
What types of energy are shown below?
Mechanical and Thermal Energy (Don’t forget friction)
What type of energy is shown below?
Light Energy
What types of energy are shown below?
Electrical, Mechanical, and Light Energy
What type of energy is shown below?
Thermal Energy
Challenge
Can you think of an object that uses or
produces all 5 types of energy?
Original Energy Product
• Design an original product with a
specific purpose that uses all 5 sources
of energy.
Due Thursday
Student work should include:
1. A labeled diagram of a product
that uses all five types of
energy
2. A written description of the
product, including an
explanation of how and why it
uses all forms of energy
3. An explanation of the specific
purpose of the product
