The mechanism by which stars produce light and heat, sustaining themselves against gravitational collapse.

• Occurs in the star's core.
• Primarily nuclear fusion of hydrogen into helium.
• Releases immense amounts of energy.

Translation on a coordinate plane involves shifting a point or figure horizontally and/or vertically without rotation or reflection. This changes its coordinates.

• Moving right: add to x-coordinate.
• Moving left: subtract from x-coordinate.
• Moving up: add to y-coordinate.

The state or process of falling into decay or disrepair.

• Often applies to buildings or structures.
• Implies neglect and structural deterioration.
• Results from age, weather, or lack of maintenance.

Weight is the force exerted on an object due to gravity, and it changes with the strength of the gravitational field.

• Weight = mass × gravitational acceleration (g).
• Gravitational force decreases with distance from the center of a planet.
• Mass is an intrinsic property and remains constant.

The quality of being prudent; cautiousness; acting with or showing care and thought for the future.

• Involves wisdom and good judgment.
• Often refers to avoiding risks or bad outcomes.
• Essential in critical or uncertain situations.

A basic arithmetic operation used to find the product of two numbers.

• Often used for 'per unit' calculations.
• Can involve decimals.
• Represents repeated addition.

In a right-angled triangle, if the hypotenuse and one leg are known, the other leg can be found using the Pythagorean theorem by rearranging the formula.

• Formula: a² + b² = c² (where c is hypotenuse).
• To find a leg: a² = c² - b² or b² = c² - a².
• Ensure correct identification of hypotenuse and legs.

The relationship between time, distance, and speed is fundamental in physics and everyday calculations. Distance is the product of speed and time.

• Distance = Speed × Time
• Speed = Distance / Time
• Time = Distance / Speed

To add mixed numbers and fractions, convert mixed numbers to improper fractions or add the whole numbers and fractions separately, finding a common denominator for the fractional parts.

• Convert mixed numbers to improper fractions for easier multiplication/division.
• Find a common denominator to add or subtract fractions.
• Simplify the final fraction if possible.

Very attentive to and concerned about accuracy and detail.

• Can also imply being difficult to please due to high standards.
• Often associated with perfectionism or extreme neatness.
• Synonyms: meticulous, scrupulous, punctilious, painstaking.

Calculating the duration of travel given a distance and a constant speed.

• Formula is Time = Distance / Rate (Speed).
• Ensure units are consistent (e.g., miles and mph).
• A rearrangement of the DRT formula (D=RT).

Intended for or likely to be understood by only a small number of people with a specialized knowledge or interest.

• Often implies something mysterious or secret to outsiders.
• Contrasts with 'exoteric' (understood by the general public).
• Synonyms: obscure, arcane, recondite, abstruse.

Problems that involve calculating a specific percentage of a given number, or finding a number based on a percentage.

• Convert percentages to decimals (e.g., 35% = 0.35) for calculations.
• To find 'X% of Y', calculate (X/100) * Y.
• Often involves multiple steps, such as finding a part and then the remainder.

Lacking flavor; dull or uninteresting.

• Can describe food, conversations, or art.
• Implies a lack of stimulating qualities.
• Often associated with mediocrity.

Subject to sudden or unpredictable changes of mood or mind.

• Often used to describe a person's temperament.
• Refers to the Roman god Mercury, known for his swiftness and unpredictability.
• Implies instability and changeability.

The magnitude of the magnetic field produced by an electromagnet, which can be controlled by several factors.

• Directly proportional to current.
• Directly proportional to the number of turns in the coil.
• Stronger with a ferromagnetic core.

A large or excessive amount of something.

• Often implies more than is necessary or desirable, but can also just mean a large quantity.
• Derived from Greek for 'fullness'.
• Synonyms: excess, surplus, profusion, abundance.

No longer produced or used; out of date.

• Often refers to technology, methods, or practices.
• Implies replacement or retirement due to newer alternatives.
• Can become obsolete due to advancements or lack of demand.

Having or showing keen mental discernment and good judgment; shrewd.

• Implies deep understanding and practical wisdom.
• Often associated with age and experience.
• Synonyms: astute, discerning, judicious.

A relationship where an increase in one quantity results in a proportional decrease in another, such that their product remains constant.

• Quantity1 × Quantity2 = Constant.
• Often involves workers and time, or speed and time.
• If workers increase, time decreases.

(Of a subject or knowledge) little known; abstruse.

• Implies a high level of complexity or specialization.
• Often used for academic or intellectual topics.
• Suggests difficulty in understanding for most people.

Proceeding in a gradual, subtle way, but with harmful effects.

• Implies something harmful that is not immediately apparent.
• Often used for diseases, threats, or ideas.
• Suggests treachery or cunning.

The process used by plants, algae, and cyanobacteria to convert light energy into chemical energy, stored in organic compounds like glucose.

• Uses sunlight, water, and carbon dioxide.
• Produces glucose and oxygen.
• Occurs primarily in chloroplasts.

The perimeter of a rectangle is the total distance around its boundary. It is calculated by adding the lengths of all four sides.

• Formula: P = 2 * (length + width)
• Units of perimeter are linear (e.g., feet, meters).
• Used for fencing, framing, or outlining rectangular areas.
