Если движение равнозамедленное ($a < 0$), то график идет вниз. Точка пересечения графика с осью скорости (осью ординат) соответствует начальной скорости $v_0$.</p><p><strong>Ответ:</strong> График скорости равноускоренного движения — это наклонная прямая.</p><p><strong>Итоговое сравнение и основное отличие</strong></p><p>Основное отличие заключается в том, что при <strong>равномерном прямолинейном движении</strong> скорость не изменяется со временем, поэтому ее график — <em>горизонтальная прямая</em> (нулевой наклон). В свою очередь, при <strong>равноускоренном движении</strong> скорость изменяется линейно со временем, поэтому ее график — <em>наклонная прямая</em> (постоянный, но ненулевой наклон).</p><p>Таким образом, отличие графиков заключается в их наклоне к оси времени: у графика равномерного движения наклон равен нулю, а у графика равноускоренного движения — наклон постоянен и не равен нулю.</p><p><strong>Ответ:</strong> График скорости равномерного прямолинейного движения — это прямая, параллельная оси времени, а график скорости равноускоренного движения — это прямая, наклоненная к оси времени. Отличие заключается в угле наклона графика к оси времени.</p>" ] #changes: [] #casts: [] #classCastCache: [] #attributeCastCache: [] #dateFormat: null #appends: [] #dispatchesEvents: [] #observables:

3. Чем отличается график скорости равномерного прямолинейного движения от графика скорости равноускоренного движения?
Решение. №3 (с. 43)
Графики скорости для равномерного прямолинейного и равноускоренного движений имеют принципиальные различия, которые следуют из определений этих видов движения.
График скорости равномерного прямолинейного движения
Равномерное прямолинейное движение — это движение, при котором тело за любые равные промежутки времени проходит одинаковые расстояния. Это означает, что скорость тела остается постоянной по величине и направлению.
Математически это выражается как $v = \text{const}$. Так как ускорение $\text{a}$ — это быстрота изменения скорости, то при равномерном движении оно равно нулю: $a = 0$.
График зависимости скорости от времени $v(t)$ для такого движения представляет собой прямую линию, параллельную оси времени (оси абсцисс). Эта линия будет расположена выше оси времени, если скорость положительна ($v > 0$), ниже — если скорость отрицательна ($v < 0$), или совпадать с ней, если тело покоится ($v = 0$).
Ответ: График скорости равномерного прямолинейного движения — это горизонтальная прямая, параллельная оси времени.
График скорости равноускоренного движения
Равноускоренное движение — это движение, при котором скорость тела за любые равные промежутки времени изменяется на одну и ту же величину. Это означает, что ускорение тела остается постоянным: $a = \text{const}$ и $a \neq 0$.
Зависимость скорости от времени при равноускоренном движении описывается линейной функцией: $v(t) = v_0 + at$, где $v_0$ — начальная скорость.
График этой зависимости $v(t)$ представляет собой прямую линию, наклоненную к оси времени. Угол наклона этой прямой к оси времени характеризует ускорение, так как тангенс угла наклона равен ускорению $\text{a}$. Если движение равноускоренное ($a > 0$), то график идет вверх. Если движение равнозамедленное ($a < 0$), то график идет вниз. Точка пересечения графика с осью скорости (осью ординат) соответствует начальной скорости $v_0$.
Ответ: График скорости равноускоренного движения — это наклонная прямая.
Итоговое сравнение и основное отличие
Основное отличие заключается в том, что при равномерном прямолинейном движении скорость не изменяется со временем, поэтому ее график — горизонтальная прямая (нулевой наклон). В свою очередь, при равноускоренном движении скорость изменяется линейно со временем, поэтому ее график — наклонная прямая (постоянный, но ненулевой наклон).
Таким образом, отличие графиков заключается в их наклоне к оси времени: у графика равномерного движения наклон равен нулю, а у графика равноускоренного движения — наклон постоянен и не равен нулю.
Ответ: График скорости равномерного прямолинейного движения — это прямая, параллельная оси времени, а график скорости равноускоренного движения — это прямая, наклоненная к оси времени. Отличие заключается в угле наклона графика к оси времени.
