Vocabulary 1
an energy resource that is replaced as fast as, or faster than, it is used
Renewable Energy Resource
energy can be transformed from one form to another, but it cannot be created nor destroyed
Law of Conservation of Energy
What is an example of energy being inefficient?
a flashlight producing thermal energy and not just radiant energy when it is turned on (My discretion will be used as there could be many correct answers)
Which form of energy does NOT involve kinetic energy?
Chemical
Which of the following is NOT an example of energy transformation?
a. A bicycle pedals to school
b. A car's engine moves a car
c. A sound wave travels across a hall
When energy moves from one object to another without changing form
Energy Transfer
When one form of energy is converted to another form of energy
Energy Transformation
What is NOT a way in which thermal energy is transferred?
Sublimation
What type of energy does a statue have on a beautiful sunny day?
Thermal Energy
What is a form of energy that cannot be stored?
Sound Energy
The energy in an electric current
Electric Energy
A disturbance that transfers energy from one place to another without transferring matter.
Wave
Defined by scientist as the ability to cause change
Energy
What form of energy relies on gravitational potential energy?
Hyroelectric
Which involves only an energy transfer?
a. A can of juice cools off in a cooler on a hot summer day.
b. A boy turns on an electric toaster to warm a piece of bread.
c. A cat jumps down from a tree branch.
The energy stored in and released from the nucleus of an atom
Nuclear Energy
The sum of the potential energy and the kinetic energy in a system.
Mechanical Energy
Stored energy due to the interaction between objects or particles.
Potential Energy
Imagine a picture of a dog laying on the snow, how does the thermal energy definitely flow?
From the dog to the snow
Waves can transfer energy, but they
Do not move matter
The energy stored in and released from the bonds between atoms.
Chemical Energy
The sum of the kinetic energy and the potential energy of the particles that make up the object.
Thermal Energy
Energy carried by electromagnetic waves
Radiant Energy
What decreases the thermal energy of a can of soup you just took out of your pantry?
Putting the can of soup in the refrigerator
Which could occur in a closed system?
a. Chemical energy is transformed to electric energy in the system
b. During a transformation of chemical energy to mechanical energy, thermal energy is released to the environment
c. Electric energy from the environment is transferred to the system
