  1. Which energy store is associated with a moving object?

    Answer: Kinetic energy store

    A moving object has energy in its kinetic energy store. Kinetic energy depends on the object's mass and speed: KE = ½mv². Doubling the speed quadruples the kinetic energy, which is why stopping distances increase greatly at higher speeds.

  2. Express 180 as a product of its prime factors.

    Answer: 2² × 3² × 5

    180 = 2 × 90 = 2 × 2 × 45 = 2 × 2 × 9 × 5 = 2² × 3² × 5. Use a factor tree to break 180 into prime factors systematically.

  3. What does 'structure' mean when analysing a text?

    Answer: How the text is organised and sequenced — including openings, endings, shifts in focus, and form

    Structure refers to how a text is organised: the order of ideas, the choice of form (sonnet, narrative, etc.), where it begins and ends, turning points, and how the writer controls the reader's journey through the text.

  4. What does HTTP stand for?

    Answer: HyperText Transfer Protocol

    HTTP stands for HyperText Transfer Protocol, the foundation of data communication on the World Wide Web.

  5. Which of the following substances has a giant covalent structure?

    Answer: Diamond

    Diamond has a giant covalent structure where each carbon atom is bonded to four others in a tetrahedral arrangement. This creates a very strong, rigid lattice, which is why diamond is extremely hard and has a very high melting point.

  6. What is an ionic bond?

    Answer: A bond formed by transferring electrons from a metal to a non-metal, creating oppositely charged ions

    An ionic bond forms when a metal atom transfers electrons to a non-metal atom. This creates positive metal ions and negative non-metal ions, which are held together by electrostatic attraction.

  7. Solve the equation 4x - 7 = 13.

    Answer: x = 5

    Add 7 to both sides: 4x = 20. Then divide both sides by 4: x = 5. You can check by substituting back: 4(5) - 7 = 20 - 7 = 13 ✓

  8. Which process is used to separate crude oil into its fractions?

    Answer: Fractional distillation

    Fractional distillation separates crude oil into fractions based on their different boiling points. The crude oil is heated and vapours rise up a fractionating column. Shorter hydrocarbons with lower boiling points rise higher before condensing.

  9. Which data type is used to store the value True or False?

    Answer: Boolean

    A Boolean data type stores only two values — True or False — and is used for logical conditions and decision-making.

  10. What is sin 30°?

    Answer: 1/2

    sin 30° = 1/2 = 0.5. This is one of the standard exact trigonometric values: sin 30° = 0.5, cos 30° = √3/2, tan 30° = 1/√3. These are worth memorising.

  11. What is the effect of the writer using a rhetorical question in a newspaper article?

    Answer: It engages the reader and encourages them to consider the writer's viewpoint

    Rhetorical questions engage the reader by inviting them to think about an issue. Because the expected answer is implied, the reader is steered towards agreeing with the writer's position without being directly told what to think.

  12. What does ASCII stand for?

    Answer: American Standard Code for Information Interchange

    ASCII stands for American Standard Code for Information Interchange, a character encoding standard used to represent text in computers.

  13. A car is bought for £8,000 and depreciates by 20% in the first year. What is its value after one year?

    Answer: £6,400

    20% of £8,000 = £1,600. Value after depreciation = £8,000 − £1,600 = £6,400. Alternatively: 80% × £8,000 = 0.8 × £8,000 = £6,400.

  14. What does LAN stand for?

    Answer: Local Area Network

    LAN stands for Local Area Network, connecting devices within a limited geographical area such as a school or office building.

  15. What is the result of the binary addition 1011 + 0101?

    Answer: 10000

    1011 (decimal 11) + 0101 (decimal 5) = 16, which in binary is 10000.

  16. A shop reduces the price of a jacket from £80 to £60. What is the percentage decrease?

    Answer: 25%

    The decrease is £80 - £60 = £20. Percentage decrease = (20 ÷ 80) × 100 = 25%. Always divide the change by the original value, not the new value.

  17. What is the probability of rolling a 4 on a fair six-sided die?

    Answer: 1/6

    A fair die has 6 equally likely outcomes (1, 2, 3, 4, 5, 6). There is one way to roll a 4, so the probability = 1/6 ≈ 0.167.

  18. What was the Beveridge Report (1942) and why was it significant for Britain?

    Answer: A report identifying five social evils and proposing a welfare state

    The Beveridge Report (1942) identified five 'Giant Evils' — Want, Disease, Ignorance, Squalor, and Idleness — and proposed comprehensive social insurance. It became the blueprint for the post-war welfare state, including the creation of the NHS in 1948.

  19. Which sorting algorithm works by repeatedly swapping adjacent elements that are in the wrong order?

    Answer: Bubble sort

    Bubble sort repeatedly compares and swaps neighbouring elements until the entire list is in the correct order.

  20. What is the difference between speed and velocity?

    Answer: Speed is a scalar (magnitude only); velocity is a vector (magnitude and direction)

    Speed is a scalar quantity — it only has magnitude (e.g., 50 km/h). Velocity is a vector — it has both magnitude and direction (e.g., 50 km/h north). This distinction is crucial in physics calculations.
