10. The other day you were guiding a hall across the oor using plastic barriers. If you were to move the level along the track you made for the rolling ball, taking the same path as the ball and going the same speed, where would the bubble be centered and where would it not? When the bubble was off-center, which direction would it be pointing? Explain by drawing a diagram showing the track and the bubble level. 1 1.
