原创歌词请勿盗版
(Verse 1)
Displacement-time 位移时间图
Straight or curved line 直线还是曲线
Gradient of the slope 坡度的斜率
velocity can be find 是速度
(verse)
Velocity-time 速度时间图
Straight or curved line 直线还是曲线
Gradient of slope 坡度的斜率
Acceleration can be find 是加速度
(Chorus)
Slope of tangent line, 切线的坡度
Instantaneous we find, 是瞬时信息
Average needs two points, 平均信息需要两个点
Keep the difference in mind. 注意区别
(music)
(Verse )
Area under the line
From acceleration-time 加速度时间图的图像面积
Change of velocity
Is what we will find 是速度的变化量
(verse)
Area under line
from velocity-time 速度时间图的图像下面积
Change of displacement 是位移变化量
Is what we will find
(Chorus)
Keep vectors in mind 把矢量给我焊死在脑子里!!!!!!
Areas are similar type 面积(即使)相似
Positive or negative 正负号不同
Story is not the same kind 讲的故事根本不是一回事!!!!
