Goodacre (crater)

Goodacre (crater) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Goodacre (crater) rather than just read about it. In short: Goodacre is a lunar impact crater. It is located in the rugged southern highlands on the Moon's near side, and is attached to the north-northeastern part of the exterior of Gemma Frisius, a heavily worn and much larger formation.

Key takeaways

Goodacre (crater) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Goodacre (crater) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Goodacre (crater) from memory before moving on to harder problems.

Reference excerpt

Goodacre is a lunar impact crater. It is located in the rugged southern highlands on the Moon's near side, and is attached to the north-northeastern part of the exterior of Gemma Frisius, a heavily worn and much larger formation. About two crater diameters to the north of Goodacre lies Pontanus. The crater is named after British selenographer Walter Goodacre. The outer rim of this crater formation has become eroded by smaller impacts, and is heavily damaged along the southern side. The somewhat distorted satellite crater Goodacre G lies across the co-joined rims of Goodacre and Gemma Frisius. The interior floor has a small central rise and there is a small crater near the northern inner wall. A trace of ray material from Tycho lies along the southwest rim and forms a wispy line that crosses the central peak.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Goodacre.

Worked examples

Example 1 — a first encounter with Goodacre (crater)

Start with the simplest possible case. Write down what Goodacre (crater) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Goodacre (crater) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Goodacre (crater) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Goodacre (crater)

In research: Goodacre (crater) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Goodacre (crater) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Goodacre (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ27 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Goodacre (crater) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
