Physics: key points

General-science physics questions cover units, basic laws, instruments and their everyday uses.

  • Learn the SI units: force in newtons, current in amperes, power in watts, resistance in ohms.
  • Know what each instrument measures: a barometer measures atmospheric pressure, a thermometer temperature.
  • Newton's three laws: inertia, force = mass × acceleration, and action and reaction.
  • Convex mirrors are used as rear-view mirrors; concave lenses correct short sight.

How to practise Physics

Start with the key points, then take one Physics test without rushing. Review every explanation, note the steps you missed and repeat the topic against the clock. APTITUDE TESTER has 10 questions in 1 test for this topic.

  • Read the method before attempting a timed test.
  • Record mistakes by type: concept, calculation or time management.
  • Return to the hardest questions after a day and try them again.

Continue with another General Knowledge topic when your accuracy is steady.

Physics: questions people ask

How many Physics questions are there?

There are 10 Physics questions in 1 test. Each test has its own page that lists the questions with their answers and solutions.

How long does a Physics test take?

A test of 10 questions has a time limit of 15 minutes, which is 90 seconds a question.

Is there negative marking?

Rules vary by set. The rules screen shows the time limit, marks, any wrong-answer penalty and calculator permission before you begin. Feedback mode has no time limit or negative marking.

Can I practise Physics without a time limit?

Yes. Choose practice mode: there is no clock, and the answer and solution appear as soon as you select an option.
