PHSC101 Exam 1 Practice Deck Vocabulary

Vocabulary flashcards covering key concepts from the PHSC101 Exam 1 Practice Deck, including electric circuits, G/R diagrams, efficiency, magnetic interactions, and speed vs. time graphs.

Electric Circuit Interactions

An interaction involving a closed circuit loop where current flows from a battery terminal, through conducting wires and a bulb or component, and back to the opposite terminal.

G/R Diagram

A Giver/Receiver diagram used to model energy transfers and interactions between objects, such as a child and a pogo stick during upward expansion or downward contraction.

Efficiency Diagram

A system diagram representing energy transfers, inputs, outputs, and losses as heat ($TE$) to the surroundings across connected components.

Magnetic Interactions

Interactions involving magnetic attraction or repulsion between magnets and ferromagnetic materials, as well as testing material conductivity in circuits.

Speed vs. Time Graph

A visual graph plotting an object's speed over time, where the slope represents acceleration or deceleration (rate of change of speed).

Law of Conservation of Energy

A physical law stating that energy cannot be created or destroyed, requiring total energy inputs to equal the sum of energy outputs and internal energy changes.

Rate of Change of Speed

The rate at which an object accelerates or decelerates, indicated by the steepness of the slope on a speed versus time graph.

Chemical Potential Energy (CPE)

Energy stored within chemical bonds, such as in a battery, that can be transformed into electrical current ($EC$).

Thermal Energy (TE)

Energy transferred as heat into the surroundings during energy conversion steps in an inefficient device or process.
