Explanation:
When a mass of 8 kg is located on the Earth's surface, the magnitude of each of
the gravitational forces attracting the mass and the Earth toward each other is
(mass) x (acceleration of gravity on Earth) =
(8.0 kg) x (9.81 m/s²) =
78.48 kg-m/s² = 78.48 newtons (about 17 pounds 10.2 ounces)
