Question 60

Easy

Figure 3 shows a diagram of a pendulum bob suspended by a string, showing its starting position (highest point) and its lowest position during a swing.

To find the gravitational potential energy lost, a student needs to measure the change in vertical height, $Δh\Delta h$ , of the bob.

A diagram titled 'Figure 3' showing a pendulum bob suspended from a fixed pivot. The bob is shown in two positions: Position A (its starting position, elevated at an angle to the right) and Position B (its lowest vertical position directly below the pivot). A dashed arc represents the path of the swing between Position A and Position B. There is a horizontal bench line drawn below Position B.

Draw a vertical ruler on Figure 3, placed in a position to measure the change in vertical height, $Δh\Delta h$ , between the starting position (Position A) and the lowest position (Position B) of the bob.
