物体无加速度地，悬挂在此，合力为零，加速度亦为零。

This object is hanging there, it's not being accelerated so the net acceleration must be zero.

加速度才为零,写出来就是：我给它的力,与重力之合力等于零。

Only now is there no acceleration so I can write down that force of Walter Lewin plus the force of gravity equals zero.

结合加速度计零位和标度因数的温度误差模型，采用了相应的误差补偿算法。

The proper error-compensation method is adopted based on the temperature error model of the accelerometer.

youdao

It knows that this particle happened to have a height of 15, at the time of 0, and a velocity of 10, and it is falling under gravity with an acceleration of -10.

这个质点恰好处在高度为15的地方,零时刻,初速为10,并在重力作用下以-10的加速度下坠
