Physics study guide on one topic: ideas explained plainly, solved problems with units and exercises with answers

Example result

Example for the Standard package

Study guide: solving linear equations, for students aged 13–14

The one rule

An equation is a balance. Whatever you do to one side, you do to the other, and the balance stays level. The goal is to get x alone on one side.

Worked example 3: the unknown on both sides

Solve 5x − 4 = 2x + 11.

  1. Move the x terms to one side: take 2x from both sides. 5x − 2x − 4 = 11, so 3x − 4 = 11.
  2. Move the numbers to the other side: add 4 to both sides. 3x = 15.
  3. Divide both sides by 3. x = 5.
  4. Check: 5 × 5 − 4 = 21 and 2 × 5 + 11 = 21. Both sides match.

Common mistake

In 3(x + 2) = 18, many students write 3x + 2 = 18. The 3 multiplies everything in the brackets: 3x + 6 = 18, so x = 4.

Exercises 7–10

  1. 4x + 3 = x + 18
  2. 2(x − 5) = 14
  3. 7 − x = 3x − 9
  4. 3(2x + 1) = 4x + 15

Answers: 7. x = 5 · 8. x = 12 · 9. x = 4 · 10. x = 6

Files: PDF and Word. The guide is for learning: we do not do homework or tests to be handed in.

Client: a parent whose daughter gets lost when an equation has brackets or the unknown on both sides. Task: a guide at middle school level that starts from the basics and builds up to those two cases. Standard package: up to 8 pages, 6 worked examples, 20 exercises with answers and a summary sheet. Excerpt below.

The client and all details are made up.

About this service

Physics problems go wrong in two places: not seeing which law applies and getting lost in units. This guide takes one topic, such as motion and its graphs, Newton's laws, energy and power, momentum, pressure, waves and sound, light, electric circuits, magnetism or heat, and explains the idea in plain words with everyday examples before the formula. Problems are solved in a fixed order: what is given, what is asked, which law, units converted, the calculation and a sense check of the answer. Common mistakes and exercises with answers follow. Force and circuit diagrams are described in words with labels for the learner to sketch. Tell us the grade or course and the textbook. The guide is for learning: we do not solve homework, lab reports, tests or exams to be handed in, and the exercises are new ones. Check the notation against your course.

What is included

  • What you getA PDF and Word file on your physics topic: the idea in plain words, problems solved in a fixed order with units, diagrams described with labels, common mistakes and exercises with answers. From Standard, a one-page summary sheet with the formulas and units; in Premium, a 20-question self-check test and a separate answer key with short explanations.
  • Idea before formulaEveryday examples that show what the law means
  • Given, find, solveThe same clear order in every solved problem
  • Units and sense checksConverting units and checking the answer is reasonable
  • Common mistakesMixed units, wrong signs for direction, mass vs weight
  • At your levelFrom school physics to an intro college course

How it works

  1. 1
    TopicYou name the topic, the grade and what is hard
  2. 2
    WritingWe write the explanation, solved problems and exercises
  3. 3
    DeliveryYou get the guide in PDF and Word on the order page
  4. 4
    StudyYou practise with it and ask for changes within your package

What we need from you

The exact physics topic, the grade or course, the curriculum and textbook, the formula sheet used in class if any, the units and notation, what the learner already knows and finds hard, the language, and how the guide will be used. You may attach a syllabus, a list of topics or a page of class notes as Word or PDF files, up to 3. Please do not send graded homework, tests or exam papers to be solved.

We will ask you:

  • Which physics topic?
  • For what level?
  • What does the learner already know, and what is hard?
  • Which curriculum or textbook should it follow?
  • Language and how the guide will be used

Questions and answers

Can you solve my physics homework or lab report?

No. The guide teaches the topic with new problems and exercises; we do not do homework, lab reports, tests or exams to be handed in as your own work.

Are diagrams included?

Force, ray and circuit diagrams are described in words with labels, so the learner can sketch them. We don't promise precise drawn pictures.

Can the guide describe experiments?

It can explain a classic experiment and its results so the learner understands it. It is not a lab manual: practical work follows your school's safety rules and your teacher's instructions.

Will it match my course?

We follow the level, curriculum and textbook you name, but programmes, notation and methods differ, so the learner or a teacher should check the guide against the course.

Can a teacher use it with a class?

Yes. Print it and share it with your learners; in Premium the test and the answer key are separate files, so you can hand out the test alone.
