匀变速直线运动是变速直线运动中最简单的运动形式,它是质点沿着一条直线,且加速度不变的运动.根据加速度的定义a=(Δv)/(Δt)=(v_t-v_0)/t可知,做匀变速直线运动的质点在相等的时间内速度改变相等,而由a=恒量
Constant speed linear motion is the simplest form of motion in variable speed linear motion. It is the motion of a mass point along a straight line with constant acceleration. According to the definition of acceleration a=(Δv)/(Δt)=(v_t-v_0)/ t It can be seen that the particles of the uniform speed change linear motion change equally in the same time, but by a = constant
