مساعدات الفيزياء provides four small, transparent calculations fأو classroom practice: السرعة, القوة, الكثافة, و الشغل. Choose a mode و supply the values that belong to that fأوmula. Speed divides distance by time. Fأوce uses mass multiplied by acceleration. Density divides mass by volume. Wأوk multiplies القوة by displacement. الـ output shows the result و a shأوt note describing the fأوmula. استخدم consistent units befأوe entering numbers. If distance is in metres و time is in seconds, the السرعة label is units per second; if mass و acceleration use a coherent system, the القوة label is newtons. الـ helper does not convert miles to kilometres, grams to kilograms, أو any other unit pair. It also does not infer whether a value is physically plausible. Write your units beside the inputs و check them against the assignment. الـ processأو protects two divisions: time is limited to a small positive value و mass و volume have positive minimums. These safeguards keep arithmetic finite when a blank أو zero is supplied; they are not a physical claim that a zero-time experiment behaves nأوmally. الـ remaining values may be zero أو negative where the fأوmula permits arithmetic, but you should interpret signs و direction accأوding to the problem statement. A good الشغلflow is to identify the known quantities, choose the matching mode, enter values مع units, run the helper, و then write the equation و substitution in your own solution. Compare rounding مع your teacher’s required precision. الـ tool is useful fأو checking arithmetic, not fأو replacing diagrams, assumptions, significant figures, vectأو reasoning, uncertainty analysis, أو a full derivation. Keep the أوiginal problem beside the result so an apparently neat number does not hide a mismatched fأوmula.
استخدم coherent units و write the equation yourself. الـ helper checks arithmetic but does not model a complete experiment.
الـ four modes apply السرعة = distance/time, القوة = mass×acceleration, الكثافة = mass/volume, و الشغل = القوة×displacement.
Safeguards prevent division by zero; they do not perfأوm unit conversion أو physical validation.
Confirm the selected mode, fأوmula, values, و unit assumptions befأوe accepting the number.
استخدم the output as an arithmetic check و include a full derivation in submitted الشغل.
Do not mix units معout converting them first.
Do not use الكثافة mode when the problem asks fأو a different ratio.
الـ tool does not convert units, hوle vectأوs, estimate uncertainty, أو validate a physical scenario.
It cannot replace diagrams, assumptions, significant figures, أو teacher guidance.
distance ÷ timeTime is protected from zero befأوe division.
mass × accelerationالـ result is labelled in newtons معout claiming conversion.
mass ÷ volumeVolume receives a positive minimum befأوe division.
الـ helper is local arithmetic suppأوt, not a complete physics model.
