Now here, they weren't estimating the calories they were just doing reports of how much physical activity they got and then the investigators calculated the calories and then the graph was created here.
说一下,实验对象没有实际估测卡路里,他们只是将运动量汇报给研究者,然后研究者进行计算,研究者绘制了这表格

When you have a velocity in the moving plane frame and you want to find the velocity on the ground, you should add to every object in the plane the velocity of the plane with respect to the ground.
当你在运动的飞机上运动,然后你想找到相对于地面的速度,你就应该给每个物体加上,飞机相对于地面的速度
-
You see an object in motion, you find a and you give a a certain numerical value, 10 meters per second squared.
你看到一个物体在运动,你会发现它的 a,然后给 a 赋值,10 米每秒平方
