Time Line为什么距离是速度时间曲线下方的面积的笔记

相关课时: 笔记详情:

Velocity is equal to displacement over time.

Displacement is velocity times  time. That's distance.

When we have the constant accelerati on.

Intial spped is 0.

Acceleration is changing velocity over changing time.

Changing time is 5 seconds.

That graph is a triangle, we know the areas formula for triangle, that areas is the displacement (distance).
