Science, Mathematics, and Physical Education Review

Vocabulary review flashcards covering balanced diet components, index laws, sports fixture schedules, kinetic particle theory, pressure concepts, and unit conversions.

Components of a Balanced Diet

The essential nutritional categories required by the body: carbohydrates, proteins, lipids (fats and oils), vitamin A, vitamin C, vitamin D, minerals (calcium and iron), water, and fibre.

$3^{x+1}$ in terms of $a$ (given $a = 3^x$)

$3a$, derived by rewriting the expression as $3^x \times 3^1$.

Claremont Lacrosse Fixture

A U13 lacrosse fixture scheduled for Saturday 7th November (2026-2027 season) at Claremont Fan Court School, Claremont Drive, Esher (KT19 9HZ), with a departure meeting time at SPGS of 7.15 and return time of 12.15.

Thermal Tyre Bursting Mechanism

The particle process on a hot day where gas particles gain energy, causing more frequent collisions with the tyre walls and an increase in gas pressure until the tyre ruptures.

Altitude Variation of Atmospheric Pressure

The phenomenon wherein atmospheric pressure decreases as altitude increases because there is less weight of atmosphere pressing down on a surface.

Gas Particle Motion

The rapid, random, and continuous motion exhibited by particles in the gas state.

Gas Pressure ($P = \frac{F}{A}$)

The total force exerted over a specific contact area resulting from gas particles colliding with the walls of their container.

Kelvin Temperature (Gas Particles)

The temperature scale that is directly related to the average kinetic energy of the gas particles.

Atmospheric Pressure at Sea Level

The standard atmospheric pressure at sea level, equal to $100\,000\text{ Pa}$ or $100\,000\text{ N/m}^2$.

Gas Properties Model Simulation

A particle simulation demonstrating how changing conditions (such as heating or cooling heavy particles) affects container pressure and temperature.

Density Unit Conversion ($\text{g/cm}^3$ to $\text{kg/m}^3$)

A conversion rule performed by multiplying the value by $1\,000$ (e.g., $1\text{ g/cm}^3 = 1\,000\text{ kg/m}^3$).

Pressure Unit Conversion ($\text{N/cm}^2$ to $\text{N/m}^2$)

A conversion rule performed by multiplying the value in $\text{N/cm}^2$ by $10\,000$.
