FLASHCARD QUESTION

Front

Energy Noun

[en-er-jee]

Back

Energy


The ability to do work or cause change; a quantifiable characteristic of a system that is transferred between objects.

Example: This diagram shows a generator converting mechanical energy (rotation) into electrical energy to power a light bulb, illustrating that energy changes form but is conserved.

FLASHCARD QUESTION

Front

Work Noun

[wurk]

Back

Work


The transfer of energy into or out of a system, resulting in a change in the system's total energy.

Example: A person does work by applying a force (pushing) to an object, causing it to move in the direction of the force.

FLASHCARD QUESTION

Front

Kinetic Energy Noun

[ki-net-ik en-er-jee]

Back

Kinetic Energy


The energy an object possesses due to its motion, which is dependent on its mass and velocity.

Example: This image shows an archer releasing an arrow. The energy stored in the drawn bow (potential energy) is converted into the energy of the moving arrow (kinetic energy).

FLASHCARD QUESTION

Front

Potential Energy Noun

[po-ten-shul en-er-jee]

Back

Potential Energy


Stored energy an object has due to its position, state, or internal structure, ready to be converted or used.

Example: This image shows that a truck's stored potential energy increases with greater height and more mass, demonstrating the key factors of gravitational potential energy.

FLASHCARD QUESTION

Front

Law of Conservation of Energy Noun

[law uv kon-ser-vay-shun uv en-er-jee]

Back

Law of Conservation of Energy


The fundamental principle stating that energy cannot be created or destroyed, only transformed from one form to another.

Example: A pendulum swings, transforming its energy from maximum potential energy at the highest points to maximum kinetic energy at the lowest point, demonstrating conservation.

FLASHCARD QUESTION

Front

Conservation (in Physics) Noun

[kon-ser-vay-shun]

Back

Conservation (in Physics)


A principle stating a specific quantifiable property of a physical system does not change as the system evolves over time.

Example: A swinging pendulum shows energy conservation: potential energy (stored energy) is highest at the peaks, while kinetic energy (energy of motion) is highest at the bottom.

FLASHCARD QUESTION

Front

System (in Physics) Noun

[sis-tem]

Back

System (in Physics)


A specific portion of the universe that has been chosen for analysis, separated from its surroundings by a boundary.

Example: In physics, a system is the specific object or group of objects being studied, separated from everything else (the surroundings) by a boundary.
