Module 1 Unit 2 Lesson 1 Energy Transfers and Transformations

Vocabulary flashcards covering types of energy, energy transfers, energy transformations, and potential to kinetic energy changes from Module 1, Unit 2, Lesson 1.

Thermal Energy

The kinetic energy ($KE$) of particles that make up matter or substances.

Direction of Thermal Energy Transfer

The rule governing heat flow, which states that hot always goes to cold.

Law of Conservation of Energy

The fundamental principle stating that energy cannot be created or destroyed, only transferred or transformed.

Mechanical Energy

A type of energy exemplified by a moving car or a rolling ball.

Electromagnetic Energy

A type of energy exemplified by sunlight, microwaves, and light waves.

Sound Energy

A type of energy exemplified by a ringing bell, heels clicking on the floor, or a speaker playing music.

Chemical Energy

Energy stored in substances, with examples including food and batteries.

Byproducts of Energy Transformations

Forms of energy into which energy is often transformed during energy transformations, specifically sound energy and thermal energy ($TE$).

Hair Dryer Energy Transformation

The energy transformation occurring when using a hair dryer, changing electrical energy into thermal energy ($TE$), kinetic energy ($KE$), and sound energy ($SE$).

Rocket Takeoff Energy Transformations

The set of energy transformations that happen when a rocket takes off, where chemical energy ($CE$) transforms into thermal energy ($TE$), kinetic energy ($KE$), sound energy ($SE$), light energy ($LE$), and gravitational potential energy ($GPE$).

Solar Water Heater Energy Transfer

The transfer of energy in a solar water heater system, which transfers electromagnetic energy into thermal energy ($TE$).

Snowball Fight Energy Transfer

The transfer of energy where kinetic energy ($KE$) and thermal energy ($TE$) come from a person's hand to the snowball.

Hockey Puck Energy Transfer

The sequence of kinetic energy ($KE$) transfer during a hit, moving from Person to Stick to Puck.

Potential Energy Changes on a Slope

The change in energy as a toy moves down steps or a marble rolls down a hill, transforming potential energy ($PE$) to kinetic energy ($KE$) as it goes from high $PE$ / low $KE$ to low $PE$ / high $KE$.
