1. Какое движение называют равноускоренным?

Решение. №1 (с. 40)

1. Равноускоренным движением называют такое движение, при котором тело движется с постоянным по модулю и направлению ускорением. Иными словами, это движение, при котором за любые равные промежутки времени скорость тела изменяется на одну и ту же величину.

Ускорение $ \vec{a} $ при таком движении является постоянной векторной величиной, то есть $ \vec{a} = \text{const} $. Траектория такого движения может быть как прямой (прямолинейное равноускоренное движение), так и криволинейной (например, параболой, как при движении тела, брошенного под углом к горизонту).

Основные кинематические уравнения, описывающие прямолинейное равноускоренное движение (в проекциях на ось, совпадающую с направлением движения):

Зависимость скорости от времени: $ v_x(t) = v_{0x} + a_x t $.

Зависимость перемещения от времени: $ s_x(t) = v_{0x}t + \frac{a_x t^2}{2} $.

Зависимость координаты от времени: $ x(t) = x_0 + v_{0x}t + \frac{a_x t^2}{2} $.

Формула для перемещения без времени: $ s_x = \frac{v_x^2 - v_{0x}^2}{2a_x} $.

Здесь $ v_{0x} $ — начальная скорость, $ v_x $ — конечная скорость, $ a_x $ — ускорение, $ t $ — время, $ s_x $ — перемещение, $ x_0 $ — начальная координата, $ x $ — конечная координата.

Ответ: Равноускоренное движение — это движение, при котором вектор ускорения тела остаётся постоянным по модулю и направлению ($ \vec{a} = \text{const} $).
