Homework Help Overview

The discussion revolves around memorizing IGCSE formulae, specifically focusing on basic physics concepts such as distance, speed, acceleration, and force. The original poster expresses difficulty in recalling 17 formulas needed for an upcoming exam and seeks mnemonic aids or strategies for retention.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss various methods for memorization, including repetition and the use of mnemonics. Some question the effectiveness of these methods, sharing personal experiences of struggle with retention despite extensive practice.

Discussion Status

The conversation includes suggestions for remembering formulas in a specific order and using unit analysis as a potential strategy. While some participants share their experiences and frustrations, there is no clear consensus on the best approach to memorization.

Contextual Notes

Participants mention the urgency of needing to remember the formulas for an exam the following day, indicating a time constraint that may influence their learning strategies.

Hey,
I need to learn uhm 17 forumlas.
Really I need to know them for tomorow.
And I just can´t remember them all.
Does anyone have a little rhyme or so I can use to remember them all?
They are the basic IGCSE forumlae, e.g
1. Distance "divided" by speed x time
2. Change In speed "Divided" by accelaration x time
3. Force "Divided" by mass x accelaration.
etc.
Anyone know a good way of remembering them?
Thank you!

Usually the best way to learn these is repetition or by using the formulas a lot.

You know actually I've repeated these formulas like 5000 times and still I go do something else then come back and I can hardly get them right.
And lol using them?
To time consuming.
But thanks!

For the ones like distance, velocity and acceleration, just remember them in that order

velocity = change in displacement/time, acceleration = change in velocity/time.

Or you could work them out using units. Example, speed has units m/s and time has units of s.

If you multiply them, your units become (m/s)(s)= m, which is a distance.

Yeah I suppose.
That would work.
Thank you!
