An object with a mass of 70 kilograms is supported at a height 8 meters above the ground. [ 5,488 joules is the potential energy of the object with respect to the ground.
Solution:
Potential energy = (70 kg) · (9.8 m/s²) · (8 m); Potential energy = 5,488 kg-m²/s²; Potential energy = 5,488 joules. ]

Weegy: Imagine that a tank is filled with water. The height of the liquid column is 7 meters and the area is 1.5 square meters (m2). The force of gravity acting on the column of water is 102,900 N. [ Solution: The volume of water is (1.5 m² x 7 m) = 10.5 m³; 10.5 m³ = 10,500 liters; Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons. ] (More)
