The ability to do work or cause change
Pendulum
Where is the minimum kinetic energy
at the far left or right
What is the formula used to calculate potential energy
U=MGH
Juggling
Where is the minimum potential energy
at the end of the path falling down before the path thrown up
An example of objects that have little thermal energy is ___________
ice
What is the definition of Nuclear Energy
potential energy that is stored in the nucleus of an atom
Energy Transformations
Example of single transformation
cell phones transforming electrical energy into electromagnetic
what does friction do to energy
it lowers the energy because the speed slows down
What is Kinetic energy ?
The energy an object has due to its motion
When Juggling, where is the maximum kinetic energy?
at the point of being thrown or caught
Factors that affect potential energy are:
mass, height, and gravity
What is Mechanical energy?
the form of energy associated with the position with the position and motion of an object
What is the definition of Electrical Energy
The energy from an electrical charge
What is an example of nuclear fission
boiling water which makes steam
Energy Transformations
What is an example of Multiple Transformations
a lightbulb makes electrical energy become light and heat energy
With respect to Conservation of Energy
How does it relate to the total amount of energy in a pendulum at any given point
as the pendulum gets slower its kinetic energy decreases
What is the formula used to calculate Kinetic energy?
Kinetic = 1/2 x mass x velocity squared
Juggling
Where is the minimum kinetic energy?
at the top of the toss when the object is at a momentary rest
In a pendulum, where is the maximum potential energy
at the start and end of a pendulum
Give two examples of objects that have Mechanical Energy
two gears grinding causing movement
hammering a nail
Give two examples of Electrical Energy
Power Lines and Light Bulbs
What is an example of nuclear fussion
turning a turbine and a generator
Explain the energy transformation between potential and kinetic energy when juggling
any object that rises of falls experiences a change in it kinetic and gravitational potential energy
With respect to the Conservation of Energy
What did Einstein find out
energy can sometimes be created by destroying matter
What factors effect kinetic energy?
Mass and Velocity
What is the definition of stored energy?
Stored energy results from the position or shape of an object
it's like energy waiting to happen
Pendulum
Where is the minimum potential energy
the center
What is the definition of Thermal Energy
the total potential and kinetic energy of the particles in an object
What is the definition of Chemical Energy
is potential energy stored in the chemical bonds that hold chemical compounds together
What is the definition of Electromagnetic Energy
waves that have some electrical properties and some magnetic properties
Explain the energy transformation between potential and kinetic energy with a pendulum
all the energy is kinetic but at the height of its swing its only potential energy

13
In a pendulum, where is the maximum kinetic energy?
the middle
Name two types of potential energy
Gravitational and elastic
When Juggling where is the maximum potential energy
The maximum potential energy is at the top of the juggle
One example of objects that have a lot of thermal energy is___________
a toaster oven
What are two examples of Chemical Energy
batteries
food
gasoline
natural gas
burning of wood
What are two examples of Electromagnetic energy
sunlight
x-rays
What is the definition of Law of Conservation of Energy
when one form of energy is transformed into another, no energy is destroyed in the process
