Describe how the vertical height of the tower could be measured accurately. - AQA - GCSE Physics - Question 3 - 2019 - Paper 1

One effective method to measure the vertical height of the tower is by using a tape measure. This process can be organized by having one person positioned at the top of the tower and another person at the bottom holding the other end of the tape measure. This allows for a direct measurement from top to bottom.

Alternatively, a laser measure may be utilized for a more precise reading, or a plumb-line can be employed to ensure that the measuring tape is vertical, thereby improving accuracy.
