有一道这样物理题:静止且盛有水的水桶有一个木球,木球的一部分体积浸没在水面以下。如果使这桶水以恒定的加速度向上运动,那么木球的浸没程度是否会改变?对这个问题,有人误以为漂浮在水面的木球浸没在水面以下的部分体积应增大,理由是:木球要以同水桶一样加速度a上升时,必须由水对球的浮力来提供这个加速度,由于水的比重不变,所以必然要以增大球的浸没体积来 There is a physical issue like this: Still and water-filled buckets have a wooden ball, part of which is submerged below the surface of the water. If this bucket of water is moved upward with a constant acceleration, then the degree of immersion of the pellet will change? To this question, it has been misunderstood that the part of the pellet floating below the water surface should be increased in volume due to: wood Ball to be the same as the same bucket acceleration a rise must be provided by the buoyancy of water on the ball to provide this acceleration, due to the same proportion of water, it is bound to increase the ball immersion volume to
