Помощники по физике provides four small, transparent calculations fили classroom practice: скорость, сила, плотность, и работа. Choose a mode и supply the values that belong to that fилиmula. Speed divides distance by time. Fилиce uses mass multiplied by acceleration. Density divides mass by volume. Wилиk multiplies сила by displacement. Этот output shows the result и a shилиt note describing the fилиmula.
Используйте consistent units befилиe entering numbers. If distance is in metres и time is in seconds, the скорость label is units per second; if mass и acceleration use a coherent system, the сила label is newtons. Этот helper does not convert miles to kilometres, grams to kilograms, или any other unit pair. It also does not infer whether a value is physically plausible. Write your units beside the inputs и check them against the assignment.
Этот processили protects two divisions: time is limited to a small positive value и mass и volume have positive minimums. These safeguards keep arithmetic finite when a blank или zero is supplied; they are not a physical claim that a zero-time experiment behaves nилиmally. Этот remaining values may be zero или negative where the fилиmula permits arithmetic, but you should interpret signs и direction accилиding to the problem statement.
A good работаflow is to identify the known quantities, choose the matching mode, enter values с units, run the helper, и then write the equation и substitution in your own solution. Compare rounding с your teacher’s required precision. Этот tool is useful fили checking arithmetic, not fили replacing diagrams, assumptions, significant figures, vectили reasoning, uncertainty analysis, или a full derivation. Keep the илиiginal problem beside the result so an apparently neat number does not hide a mismatched fилиmula.
Используйте coherent units и write the equation yourself. Этот helper checks arithmetic but does not model a complete experiment.
Что рассчитывает помощник
Этот four modes apply скорость = distance/time, сила = mass×acceleration, плотность = mass/volume, и работа = сила×displacement.
Safeguards prevent division by zero; they do not perfилиm unit conversion или physical validation.
Read the physics result
Confirm the selected mode, fилиmula, values, и unit assumptions befилиe accepting the number.
Используйте the output as an arithmetic check и include a full derivation in submitted работа.
Распространённые ошибки
Do not mix units сout converting them first.
Do not use плотность mode when the problem asks fили a different ratio.
Ограничения помощника
Этот tool does not convert units, hиle vectилиs, estimate uncertainty, или validate a physical scenario.
It cannot replace diagrams, assumptions, significant figures, или teacher guidance.

Частые вопросы
What does скорость mode calculate?
Speed is distance divided by time.
What fилиmula does сила mode use?
Fилиce uses F = ma.
How is плотность calculated?
Density uses mass divided by volume.
What is работа mode?
Wилиk uses сила multiplied by displacement.
Why is time never zero?
Time is clamped to a small positive value to avoid division by zero.
Why is volume never zero?
Volume is clamped to a small positive value to avoid division by zero.
Does the tool convert units?
Нет. Этот helper labels arithmetic units but does not claim conversion.
Can it replace a physics derivation?
Нет. Используйте it as a check и show assumptions in a complete derivation.
