## Glossary

The glossary activity module enables participants to create and maintain a list of definitions, like a dictionary, or to collect and organise resources or information.

Glossaries have many uses, such as

- A collaborative bank of key terms
- A ‘getting to know you’ space where new students add their name and personal details
- A ‘handy tips’ resource of best practice in a practical subject
- A sharing area of useful videos, images or sound files
- A revision resource of facts to remember

## Abiogenesis | |||
---|---|---|---|

The emergence of life forms emerging from non-living chemical systems. In contrast with spontaneous generation, abiogenesis is not a process that biologists think continues in a particular environment, such as a planet or moon, once a living system has emerged.

## Abrasion | |||
---|---|---|---|

Abrasion is the physical process of rubbing, scouring, or scraping whereby particles of rock (usually microscopic) are eroded away by friction. The term Examples: 1. Abrasion (or “ 2. Coastal abrasion occurs as breaking waves which contain sand and larger fragments erode the shoreline or headland. This removes material resulting in undercutting and possible collapse of unsupported overhanging cliffs. 3. The intensity of abrasion depends on the hardness, concentration, velocity and mass of the moving particles.

## Academia | |||
---|---|---|---|

Meaning/Definition: A collective term for the scientific and cultural community engaged in higher education and research, taken as a whole. The word comes from the akademeia just outside ancient Athens, where the gymnasium was made famous by Plato as a center of learning. The definition of academia is the world within an educational community. Examples: The college does not have any sports teams because its focus is solely on its Gail found the real world of business to be quite different from what she learned in Cara wanted to go to Harvard University because of the school’s great reputation in Source: https://en.wikipedia.org/wiki/Glossary_of_education_terms_(A%E2%80%93C)

## Accelaration | |||
---|---|---|---|

The change in an object's velocity over time, measured in distance per unit time per unit time (for example meters per second per second or m/s2). Compare to velocity. Acceleration (a) is calculated by dividing the change (symbolized by Δ, the Greek letter delta) in velocity (v) by the change in time (t): a = Δv/ Δt. This can also be written as: a = v2-v1/ t2-t1, where v1 and t1 denote the starting velocity and time and v2 and t2 denote the ending velocity and time. To illustrate, imagine a car speeding up (accelerating) from a stand still (0 meters/second) to a speed of 15 meters/seconds over the course of 5 seconds. The car's total increase in velocity is 15 meters/second. During each of the 5 seconds that the car is accelerating, its velocity increases by 3 meters/second until it reaches its top speed. (After one second the car is traveling at a velocity of 3 meters/second; after 2 seconds, it's traveling at a velocity of 6 meters/second, and so on). Therefore, the car's rate of acceleration is 3 meters per second per second or 3 m/s2. Using the equation above: a = v2-v1/ t2-t1 a = 15-0 / 5-0 a = 15/5 a = 3 m/s2
At different points on Earth, objects fall with an acceleration between 9.78 and 9.83 m/s2 depending on altitude and latitude, with a conventional standard value of exactly 9.80665 m/s2
