For problems with calculations use UDRSS: ◻Units ◻Data ◻Relationship ◻Substitution ◻Solution

- GPE = G·m·h
- G = 9.8 m/s
^{2} - m = mass (kg)
- h = height (m)
- GPE energy unit is the Joule (J)

- What is the GPE of a ball with a mass of 0.5 kg and a height of 10 meters above the ground?

- What is the GPE of a person standing at the top of a ladder with a height of 15 meters? The person has a mass of 80 kg.

- What is the GPE of a bowling ball with a mass of 1.5 kg and held 2 meters above the ground?

- What is the GPE of a car with a mass of 505 kg and a height of 40 meters above the ground? (It’s falling off of a cliff)

- What is the GPE of a vase with a mass of 0.05 kg and a height of 3.4 meters above the ground?

- A ball with a mass of 0.3 kg and a GPE of 30 J is how far above the ground?
