Question

The reason that the level works as an acceleration detector is because, while the level itself moves in the direction of motion, the bubble inside moves in the direction of acceleration. With this information, please answer Questions 1 through 3. Suppose the level moves with a constant velocity towards the right. How will this affect where the bubble is located? Circle the correct picture on the right, and explain why this is correct. Now, suppose that the level moves with constant acceleration to the right. How does this affect the location of the bubble? Circle the correct picture on the left, and explain why this is correct.

Explanation / Answer

1. When the level is moving with constant velocity there will be no force (acceleration) on the liquid inside the level so the bubble will remain in the centre. So the first option is right

2. When the level accelerates towards right , the liquid resists to get accelerated ( inertia) so it tries to remain back which will send the bubble towards right. So second figure is right
