More Types of Energy Flashcards
What are the types of energy?
Light Heat Chemical Kinetic Electrical
A roller coaster speeds along it’s track. What type of energy does it have and why?
A roller coaster speeding along it’s track has Kinectic energy because it is moving.
Why does a roller coaster have Potential Energy when it slows to a stop at the top of a hill?
It has Potential Energy because it has the potential to move because it is above the ground and has somewhere to go.
Can Potential Energy be changed to Kinetic Energy?
Yes, Potential Energy can be changed into Kinetic Energy.
Can Kinetic Energy can be changed into Potential Energy?
Yes, Kinetic Energy can be changed into Potential Energy.
Coin Example:
A coin laying on the table has ____ energy.
A coin laying on the table has _no___ energy.
Holding a coin in you hand, alters the coins original position. The coin has _________, because it has ability to do change.
Holding a coin in you hand, alters the coins original position. The coin has potential energy, because it has ability to do change.
Dropping the coin in the bank, changes the stored energy into motion. This transfers the coin’s energy from _______ energy to______ energy.
Dropping the coin in the bank, changes the stored energy into motion.
This transfers the coin’s energy from potential energy to kinetic energy.
Substances like wood, coal, oil, and gasoline have stored energy because of their chemistry – they can _______.
Substances like wood, coal, oil, and gasoline have stored energy because of their chemistry – they can burn.
Temperature measure what kind of energy?
Temperature measures a kind of energy called Thermal Energy.
Where does Thermal Energy come from?
Thermal Energy comes from the motion of atoms in matter.
What is Thermal Energy also called?
We call thermal energy that is flowing heat.
What is Temperature?
Temperature is the measurement we use to make the sensations of hot and cold more precise.
What is a thermometer?
A thermometer is an instrument used to accurately measure temperature.
What are examples of Thermal Energy:
Boiling water on a stove.
Melting ice cube held in your hand.
Who was the first person to use a mercury thermometer?
Gabriel Fahrenheit, a German physicist, was the first person to use a mercury thermometer.
Who invented a temperature scale in which there were 100 degrees between freezing and boiling?
Anders Celsius, a Swedish astronomer, invented a temperature scale in which there were 100 degrees between freezing and boiling.
What are the boiling and freezing points in Celsius and Fahrenheit scales?
Celsius 100 degrees boiling, 0 degrees freezing
Fahrenheit 212 degrees boiling, 32 degrees freezing
What is Mechanical Energy?
Energy related to the movement of objects or its position in gravity.
What is Radiant (Light) Energy?
Energy that travels in waves (carries light, heat, or radiation).
What is Electrical Energy?
Energy that moves electrical charges.
What is Sound Energy?
Energy produced by vibration of particles.
What does “conserve” mean?
Conserve means “save”
What is the law of conservation of energy?
The law of conservation of energy says that energy can never be created or destroyed, just converted from one form into another.
What forms of energy does the law of conservation of energy apply?
The Law of Conservation of Energy applies to ALL forms of energy.
Describe any two energy transformations.
The yo-yo changes from potential energy to kinetic energy once it drops. Energy from the sun is absorbed to generate electricity. A battery powered robot is able to walk, talk and light up.
