Below are sample questions representative of the exercises included on this worksheet and related 7.79 Energy Forms and Transformations skill assessments:

Problem 1Difficulty: Mastery

A student sees four proposed energy diagrams for a battery-powered robot arm lifting a block. Which diagram would be scientifically best?

Achemical energy in battery -> electrical energy -> kinetic energy of motor and arm -> gravitational potential energy of block, with thermal energy

Bthermal energy in air -> stored chemical energy in block -> kinetic energy of battery only

Celectrical energy in block -> chemical energy in motor -> light energy in battery, with no thermal energy

Dgravitational potential energy of block -> sound energy -> electrical energy, with energy created

Solution & Explanation:The battery stores chemical energy, the circuit carries electrical energy, the motor moves the arm, and the lifted block gains gravitational potential energy. Real systems also produce heat.

Problem 2Difficulty: Mastery

A student makes a model of an energy-efficient LED bulb. The model shows 10 J of electrical energy entering, 8 J of light leaving, and an unlabeled arrow for the remaining energy. What should the unlabeled arrow show?

A2 J of chemical energy created

B2 J of thermal energy

C0 J because the energy disappeared

D18 J of sound energy

Solution & Explanation:The inputs and outputs must total the same amount. If 10 J enters and 8 J becomes light, the remaining 2 J is mostly thermal energy.

Problem 3Difficulty: Mastery

An electric bell uses a battery, an electromagnet, a moving hammer, and a metal gong. Which energy chain best traces the bell's operation?

Achemical energy -> electrical energy -> magnetic interaction and kinetic energy -> sound energy and thermal energy

Bsound energy -> electrical energy -> chemical energy -> gravitational potential energy

Ckinetic energy -> stored chemical energy -> electrical energy -> energy destroyed

Dthermal energy -> chemical energy -> light energy -> elastic potential energy

Solution & Explanation:The battery supplies electrical energy to an electromagnet. The hammer moves and strikes the gong to produce sound, with some heat produced by the circuit and motion.
