What is the stored energy of an object or material due to its position.
potential energy
mechanical energy
thermal energy
chemical energy
This is the energy associated wityh the movement of electrons through a wire or circuit.
electrical
mechanical
nuclear
kinetic
This is the energy of an object due to its motion, position, or condition. It's the combined total of potential and kinetic energy of an object.
motion energy
mechanical energy
nuclear energy
thermal energy
The faster an object moves, the more of this type of energy it has.
moving
potential
kinetic
gravitational
This is the energy of an object due to the motion of its atoms and molecules.
chemical energy
sound energy
radiant energy
thermal energy
This type of energy travels in waves and is able to move through empty space.
radiation (radiant)
nuclear
weaponized
gerbil
This is the energy of vibrations carried through solids, liquids, or gases. It travels in waves, but cannot move through empty space or a vacuum.
heat
sound
radiant
formulary
All energy can change from one of these to another.
form
transfer
transformation
potato-------
This is the energy produced when an atom splits apart (fission) or when two atoms join to form one atom (*fusion).
electrical
atomic
thermal
nuclear
Plants use energy from the sun in the process of photosynthesis to manufacture glucose. The energy transformation is:
radiant to chemical
thermal to mechanical
electrical to radiant
radiant to thermal
Solar panels placed on the top of a roof use the sun's energy to heat water for a swimming pool The energy transformation is:
radiant to mechanical
radiant to thermal
radiant to sound
thermal to electrical
A lamp is plugged into a wall socket. Once the lamp is turned on, both light and heat come from the lamp. The energy transformation is:
electrical to radiant and potential chemical
electrical to radiant and thermal
electrical to radiant and nuclear
electrical to radiant and mechanical
If you rub your hands together, you will feel the effects of FRICTION. What energy transformation took place?
kinetic to thermal
mechanical to thermal
potential to thermal
thermal to kinetic
If you bounce a tennis ball on the ground, it will bounce back up, but not to the original height from where it was dropped. What is taking place, energy-wise speaking?
At impact, the kinetic energy is transferred to the floor, and converted to heat and sound. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.
At impact, the potential energy is transferred to the ball itself, and converted to chemical and sound energies. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.
At impact, the kinetic energy is transferred to the ball itself, and converted to heat and sound. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.
At impact, the mechanical energy is transferred to the ball itself, and converted to kinetic and sound energies. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.
If you want to make a homemade rocket, you can mix baking soda and vinegar. The top of the bottle will fly off. What are the energy transformations taking place?
chemical energy to thermal energy
chemical energy to heat
chemical energy to potential energy
chemical energy to kinetic energy
This image/caption describes which scientific law/theory?
The Law of Conservation of Energy
The Theory of Conservation of Energy
The Law of Conservation of Mass
Newton's Fourth Law of Motion
Which statement summarizes the Law of Conservation of Energy?
Energy is never created, but can be destroyed when heat is created in an exchange
Energy is never created or destroyed; it is only transformed from one form of energy to another.
Energy is never created or destroyed. It is only created when energy is created from matter.
Energy is never destroyed or created except when there is a nuclear reaction.

A ball sitting at the top of a ramp. As the ball rolls down the ramp, the potential energy of the ball decreases. What happens to the potential energy as the ball moves?
It is lost as gravitational energy
It is converted to kinetic energy.
It is used to make the ball slow down
it is destroyed as the ball moves
Damon is a musician playing in a band. At the end of a song, he plucks a single guitar string. The string moves rapidly back and forth. Which of these statements explained what happens to the kinetic energy of the moving string?
the kinetic energy is changed into potential energy and stored.
The kinetic energy is converted into sound energy and thermal energy
The kinetic energy is destroyed as the string moves until none remains.
Some of the energy is converted to sound energy and the rest is destroyed.
