1.
Define nonrenewable resource.
a)
Energy that can not be remade quickly or reused. Once it is used up, it is gone.
b)
Energy that can be remade quickly and reused. It is never gone.
2.
What are the two types (categories) of Energy?
a)
Kinetic & Potential
b)
Potential & Electrical
3.
Define potential energy.
a)
Energy of position / stored energy.
b)
Energy of motion.
4.
Define kinetic energy.
a)
Energy of motion.
b)
Energy of position / stored energy.
5.
When does an object have more potential energy?
a)
The higher it is from the ground.
b)
The closer it is to the ground.
6.
When does an object have more kinetic energy?
a)
When it hits the ground/reaches bottom point OR when it has more mass.
b)
When it hits the sky/reaches top point OR when it has less mass.
7.
Think of the Energy Skate Park. When did the skater have the greatest potential energy? Explain.
a)
The skater had the greatest potential energy when he was at the top of the track because he is the highest point it will go.
b)
The skater had the greatest potential energy when he skater was at the bottom of the track because it is the lowest point he will go.
8.
List the 7 forms of Energy Sources. (BEN TEN's cousin)
a)
(MARC TEN) Mechanical, Acoustic, Radiant, Chemical, Thermal, Electrical, Nuclear
b)
(MARC TEN) Mechanical, Acoustic, Radiant, Chemical, Thermal, Energy, Nonrenewable
9.
Think of the Energy Skate Park again. When did the skater have the greatest kinetic energy? Explain.
a)
The greatest kinetic energy would be at the point at the bottom of the track because it is closest to the ground and in motion.
b)
The greatest kinetic energy would be at the point at the top of the track because it is farthest from the ground and is not in motion.
10.
What kind of energy is created when 2 objects interact with each other?
a)
thermal
b)
kinetic
11.
What energy type/category do fossil fuels (coal, oil, and natural gas) have before they are burned?
a)
Thermal
b)
Potential
12.
What is the "law of conservation of energy"?
a)
Energy can not be created or destroyed - only transformed from one form to another.
b)
Energy can be created or destroyed and be transformed from one form to another.
13.
According to the Law of Conservation of Energy, energy that is used does not disappear. It usually is given off as what form of energy?
a)
Thermal
b)
Kinetic
14.
What kind of energy transformation occurs when you turn on a radio?
a)
electrical to acoustic
b)
electrical to thermal
15.
Electricity is produced in a hydroelectric plant when moving water turns a turbine. Which describes this energy transformation from the turning turbine to electricity?
a)
mechanical to electrical
b)
electrical to thermal
16.
What two forms of energy does a flame from a burning candle release?
a)
thermal and radiant
b)
electrical to thermal
17.
One day after school, Hannah and Daniel practiced shooting arrows with their school's archery club. As each student carefully drew the arrow back, the bow string became taut. The farther back they pulled the arrows, the harder it became to hold the arrows in place. After aiming, each archer let go of his or her arrow. The arrows flew through the air and struck the target. Which statement best describes the energy changes that took place when the arrows were released?
a)
potential to kinetic
b)
kinetic to potential
18.
Some people use calculators with solar cells that harness the Sun's energy. What energy transformation takes place within these solar cells?
a)
radiant to electrical
b)
electrical to thermal
19.
In a picture - be able to identify where the kinetic energy is and the potential energy.
Where is the greatest amount of kinetic energy?
Where is the greatest amount of kinetic energy?
a)
X
b)
Y
