Journal of Applied Physics

Journal of Applied Physics is a physics 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 Journal of Applied Physics rather than just read about it. In short: The Journal of Applied Physics is a peer-reviewed scientific journal with a focus on the physics of modern technology. The journal was originally established in 1931 under the name of Physics, and was published by the American Physical Society for its first 7 volumes.

Key takeaways

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

Reference excerpt

The Journal of Applied Physics is a peer-reviewed scientific journal with a focus on the physics of modern technology. The journal was originally established in 1931 under the name of Physics, and was published by the American Physical Society for its first 7 volumes. In January 1937, ownership was transferred to the American Institute of Physics "in line with the efforts of the American Physical Society to enhance the standing of physics as a profession". The journal's current editor-in-chief is Julia R. Greer of the California Institute of Technology. The journal is part of AIP Publishing's Subscribe to Open pilot program. According to the Journal Citation Reports, the journal has a 2025 impact factor of 2.7.

Worked examples

Example 1 — a first encounter with Journal of Applied Physics

Start with the simplest possible case. Write down what Journal of Applied Physics claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Journal of Applied Physics 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 Journal of Applied Physics 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 Journal of Applied Physics

In research: Journal of Applied Physics appears in physics 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 Journal of Applied Physics 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: Journal of Applied Physics is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic journals established in 1931, American Institute of Physics academic journals, English-language journals, so understanding it makes those chapters shorter.
In everyday life: Look for Journal of Applied Physics 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.
