0625 Physics Formula Sheet 2020

Physics is full of formulas, it’s easy to forget or mix them up!

Here is a compilation of the different formula you may need to use for your upcoming IGCSE Physics 0625 examinations.

You would need to memorise these formulas, as they are not given in your examinations and you are NOT allowed to bring these in.

There is no guarantee that you would excel in your examinations by relying on this sheet… you would still need to know how to use the formulas!

Happy practising!!!

Physical Quantities with different names but are the same

Some physical quantities have many variations although they are essentially the same type of quantity. In this video, Teacher Zyen explains three of the different terms that are the same as “length”.

Here are some of the physical quantities that have many variations with different meanings, but are actually still the same type of quantity.

Length (S.I. Unit: metre)

  • width
  • breadth
  • height
  • distance
  • displacement
  • radius
  • diameter
  • thickness

Force (S.I. Unit: Newton)

  • weight
  • tension
  • resistant force
  • drag
  • thrust
  • lift

Voltage (S.I. Unit: Volt)

  • potential difference
  • electromotive force

Examples of S.I. Units

What are S.I. Units and why do we need them? Teacher Zyen explains it in this video.

Here is a list of S.I. Units of some common physical quantities.

Our YouTube Channel Has Just Been Launched!

Yes, it’s brand new.

Yes, it’s still empty.

But we are in the midst of taking LOADS of videos and editing them as we are writing this blogpost!

New videos will be posted every week, with videos focused on Physics! We will be sharing video lessons suitable for SPM, IGCSE O-Levels and homeschoolers, and if possible for other levels as well including A-Levels, EdExcel and others!

It will not only be for education… we will also be sharing fun facts and general information related to Science and Physics!

Plus, we will also be sharing videos on how to run your own experiments at home, for fun and for learning!

Be the first to subscribe to our channel! You will receive notifications on when the latest videos are released. Click here to visit our YouTube channel.

Don’t forget to Like our Facebook Page as well… different resources will be shared there! Click here to view our Facebook Page.

The more Likes and Subscribes, the more resources we can share! Thank you for your support!

Physics Rox 2020

Wondering what’s in store for Physics Rox website?

We have the following in progress:

  • Physics Rox YouTube Channel – video lessons for Physics SPM, IGCSE O-Levels and homeschoolers, as well as general Science knowledge. Plus, science experiments you can do at home ~ great for all ages!
  • Physics Rox in Bahasa Melayu – support will be given for our BM readers!
  • Physics Rox Notes and Questions for IGCSE – to help you prepare for the IGCSE exams!

Will there always be Free Basic Notes and Guides? Yes, we will continue to offer free notes and guides for those of you who need the educational support!
