there are two forms of energy:

kinetic energy and potential energy

which is an example of kinetic energy

• running/walking

  car in motion

  flowing water

  spring bouncing

  light shining

• car at the top of a hill

  water behind a dam

  stretched spring

  light switch that is off

  yo-yo

Answer explanation

KE: is associated with movement (energy of motion

PE: due to structure or location (stored energy as a result of structure or position)

____ law of thermodynamics: energy cannot be created or destroyed but can be transformed

Answer explanation

energy transfers are not 100% efficient

(frequently lost/unusable energy is heat)

____ law of thermodynamics: energy transformations increase the entropy (degree of order) of a system, resulting in less energy available to do work

Answer explanation

any spontaneous process must increase the entropy in the system (universe), resulting in less energy to do work

-living things are ____ ordered but use energy to ___ that order

-from both the first and second ____ of ____ we know that energy transfers are not ____ efficient

-this can result in loss of energy typically ___

-every time we transform/transfer energy we increase _____

Answer explanation

entropy is the randomness/disorder of the system

these everyday activities like metabolizing food (potential energy stored in chemical bonds) to allow movement (aka kinetic energy)
