The lowest point in Death Valley is $85.0 \mathrm{m}$ below sea level. The summit of nearby Mt. Whitney has an elevation of $4420 \mathrm{m}$. What is the change in gravitational potential energy of an energetic $65.0 \mathrm{kg}$ hiker who makes it from the floor of Death Valley to the top of Mt. Whitney?

Key Concepts

Height Difference (Elevation Change)

Height difference, or elevation change, refers to the vertical distance between two points, which is crucial when calculating changes in gravitational potential energy. The greater the difference in elevation, the larger the change in energy, assuming mass and gravitational acceleration remain constant.

Use of the Formula ?PE = mgh

The formula ?PE = mgh provides a straightforward way to calculate the change in gravitational potential energy, where m is the mass of the object, g represents the acceleration due to gravity, and h is the height difference between two positions. This relationship is a fundamental tool in solving problems related to energy changes in a gravitational field.

Gravitational Potential Energy

Gravitational potential energy is the energy an object possesses because of its position within a gravitational field. It is determined by the object's mass, the local gravitational acceleration, and its height relative to a chosen reference level. This concept is essential in understanding how energy is stored and transformed when objects are moved vertically in a gravitational field.
