Question 24

A miniature motorized winch system lifts a geological core sample of mass 0.165 kg inside a portable analysis chamber.

During an extraction test, the sample is lifted vertically through a height ( $Δh\Delta h$ ) of 60.0 cm.

The gravitational field strength, $g$ , is 10 N/kg.

Calculate the change in the gravitational potential energy ( $ΔGPE\Delta \text{GPE}$ ) of the sample.

Use the equation:

\Delta \text{GPE} = m \times g \times \Delta h
