Natural Sciences, Mass, and Density

Vocabulary flashcards covering formal and factual sciences, scientific characteristics, and physical measurements like mass, weight, and density calculations.

Formal Sciences

Branch of science that studies abstract ideas, such as mathematics and logic.

Factual Sciences

Branch of science that studies reality and natural phenomena, such as biology and physics.

Science

A body of knowledge that seeks to explain and understand natural phenomena through the scientific method, based on evidence.

Empirical Science

Science that relies on experience, observation, and experimentation to provide testable evidence.

Verifiable and Reproducible Knowledge

Key qualities of scientific knowledge that ensure results are real rather than errors or coincidences.

Objective Science

A characteristic of science where conclusions are made based on evidence without personal opinions.

Systematic Science

A characteristic of science that follows an ordered and structured process.

Explanatory Science

A characteristic of science that explains and predicts why natural phenomena occur.

Onchocerciasis Vaccine

An example cited in the notes illustrating how science generates reliable knowledge.

Mass

The quantity of matter contained in a body, measured in units such as grams ($g$) or kilograms ($kg$).

Weight

The force of gravity pulling on a body, measured in Newtons ($N$).

Density Formula

The formula representing mass divided by volume, written as $\rho = \frac{m}{V}$.

Liquid Density Calculation

The density of a liquid with mass $m = 150\,g$ and volume $V = 100\,cm^3$, calculated as $\rho = 1.5\,g/cm^3$.

Aluminium Mass Calculation

The mass of $50\,cm^3$ of aluminium ($Al$) with a density of $2.7\,g/cm^3$, calculated as $m = 135\,g$ or $0.135\,kg$.

Copper Volume Calculation

The volume of a copper ($Cu$) block with a mass of $890\,g$ and density of $8.9\,g/cm^3$, calculated as $V = 100\,cm^3$.
