Below are sample questions representative of the exercises included on this worksheet and related 8.56 Energy Conservation and Transformation Chains skill assessments:

Problem 1Difficulty: Mastery

A roller coaster starts from rest at the top. At the bottom, it is moving fast but is already slightly warmer and the air near the track is turbulent.

Which chain best describes the energy changes from top to bottom?

AGravitational potential energy → electrical energy → kinetic energy

BGravitational potential energy → kinetic energy + thermal energy (coaster/track/air) + sound energy

CThermal energy → gravitational potential energy → kinetic energy

DKinetic energy → gravitational potential energy → thermal energy

Solution & Explanation:Not all potential energy becomes motion. Friction and air drag transform part into heat and sound, and turbulence increases the air’s internal energy.

Problem 2Difficulty: Mastery

A student measures 500 J of electrical energy delivered to a motor lifting a load. The load’s gravitational potential energy increases by 320 J. "

What best accounts for the remaining 180 J?,A. It is destroyed because only useful energy counts. | B. It is stored as extra gravitational potential energy of the room. | C. It becomes chemical energy in the metal wires. | D. It is transformed mostly into thermal energy (and some sound) due to friction in gears

Solution & Explanation:the rest must be in other forms

Problem 3Difficulty: Mastery

A metal spoon is left in a cup of hot tea. After a while, the spoon becomes warm even though it is not touching the heat source directly.

Which chain best describes the energy transfer?

AChemical energy in tea → electrical energy in spoon → thermal energy in air

BThermal energy in tea → thermal energy in spoon (conduction) → thermal energy to surrounding air

CGravitational potential energy → kinetic energy → thermal energy

DLight energy → thermal energy in spoon → chemical energy in air

Solution & Explanation:Heat flows from hotter tea to cooler spoon by conduction. The warmed spoon then transfers heat to the air. This is energy transfer (mostly thermal), not a new energy form being created.
