200
the energy of a book on a book shelf
What is gravitational potential energy?
200
the unit for any type of energy
What is a joule?
200
the energy transformation that occurs when an apple falls from a tree.
What is gravitational potential energy to kinetic energy?
200
the kinetic energy of a 10 kg object traveling at 4m/s
What is 80 J?
200
the force that does all the work after the first hill
What is gravity?
300
the type of energy in a stretched rubber band
What is elastic potential energy?
300
energy in the bonds of atoms
What is chemical potential energy?
300
this is what energy does because it cannot be created or destroyed.
What is changes forms? (transforms)
300
the only time the second hill can be the same height as the first hill
What is when there is no friction?
400
the energy found in a battery
What is chemical potential energy?
400
energy due to an object's position or configuration
What is potential energy?
400
the energy transformations in a bow shooting an arrow UP into the air and it falling to the ground.
What is elastic potential energy (stretched bow) --> kinetic energy (arrow being shot) --> gravitational poential energy (arrow going up into air) --> kinetic energy (arrow speeding up on the way down to the ground)
400
the TME of a 10 kg rock that is 10 m above the ground and falling at a speed of 3 m/s?
What is 1025 J?
400
the types of energy a coaster has halfway down a hill
What is potential and kinetic?
500
the energy that results from friction
What is thermal energy (heat energy)?
500
the sum of all the kinetic and potential energy in an object
What is mechanical energy?
500
the energy transformations in a car burning gasoline
What is chemical potential energy (in the gas) --> thermal energy (heat) once it is burned --> mechanical energy (movement of engine parts) --> kinetic energy (car in motion)
500
the speed of a 1 kg arrow that has 100 J of kinetic energy
What is 10 m/s?
500
the way a roller coaster stops
What is kinetic energy is transformed into heat energy due to friction?
