Unit 2 - Energy and Energy Management

advertisement
Unit 2: Energy & Energy Management – In this unit I will learn that there are different categories and forms
of energy and that these forms of energy cannot be created or destroyed, only transformed - The Law of Conservation of Energy.
I will also increase my knowledge of how thermal energy is exchanged between substances through heat transfer by conduction,
convection, and radiation.
Forms of Energy
All forms of energy fall under two categories
Kinetic Energy (Motion)
Potential Energy (Stored/Position)
Electrical
Radiant
Chemical
Nuclear
Thermal
Sound
Mechanical

TEK 6.9B verify through
investigations that
thermal energy moves in
a predictable pattern
from warmer to cooler…
The height of an object’s
position, its mass and the
field of gravity affects the
object’s potential energy.
The mass and the velocity
of an object affect the
object’s kinetic energy.
Heat (Thermal Energy)
always moves from a
warmer substance to a
cooler substance.
Heat moves until a
Thermal Equilibrium has
occurred (Where a
common/equal temperature
has been reached.)


I can compare and contrast potential and kinetic energy.

I can define and provide examples of conduction,
convection and radiation.

I can describe the movement of thermal energy.

I can give several examples of energy transformation.

I can describe the advantages and disadvantages of using
renewable and non-renewable resources.

I can provide examples of how to conserve energy at
home or school.

5. Describe the energy transformation(s) that occurs when: a) a battery operated remote is used to control a toy car; and
b) falling water runs through a hydroelectric power plant, turning giant turbines in the plant which produces electricity that is
carried by wires into homes where it powers electric heaters. Describe the energy transformations that have taken place.
