Question:
This diagram shows the Earth’s gravitational field.
a. Copy the diagram and add arrows to show the direction of the field.
b. Explain why the formula for potential energy gained (mgΔh) can be used to find the increase in potential energy when an aircraft climbs to a height of 10,000 m, but cannot be used to calculate the increase in potential energy when a spacecraft travels from the Earth’s surface to a height of 10,000 km.
