Mass and weight are very different.
Mass and weight are very different.
Mass = the matter in an object. Mass is measured in kilograms.
Weight results from gravity pulling on a mass. Gravity gives masses weight. Weight is a force! Weight is measured in Newtons.
Weight is calculated by multiplying the mass of an object by the acceleration due to gravity. Weight = mg.
Earth
Earth
On Earth, the acceleration due to gravity is 9.8 m/s/s. Earth’s larger mass results in a larger acceleration due to gravity as compared to the moon. In other words, you weigh more on Earth; you would weigh less on the moon.
Moon
Moon
On the moon, the acceleration due to gravity is 1.622 m/s/s. if you take a 10 kg bowling ball to the moon, it would still have a mass of 10 kg. However, its weight would be much less because the moon’s gravity is relatively weak.
Mass on Earth = 10 kg
Acceleration due to gravity = 9.8 m/s/s
Weight on Earth = mg
Weight on Earth = 10 * 9.8
Weight on Earth = 98 Newtons
Mass on Moon = 10 kg
Acceleration due to gravity = 1.622 m/s/s
Weight on Moon = mg
Weight on Moon = 10 * 1.622
Weight on Moon = 16.22 Newtons
