Question

If the average mass of an adult is 86kg. Determine the mass and weight of an 86kg man in the moon where gravitational field is one-sixth that of the earth.

Answer 1

Answer:

See the explanation below, and the different answers

Explanation:

It is important to clarify that the mass is always preserved, that is, it does not vary regardless of the location of the person, whether the moon, Saturn, Mars. The value that changes is the weight, due to the gravity of each planet.

On Earth

m = 86[kg]

w = m * g

where:

g = gravity acceleration = 9.81[m/s^2]

w = weight = [N]

w = 86 * 9.81

w = 843.66 [N]

On the Moon

m = 86[kg]

w = m * g

where:

g = gravity acceleration * (1/6) = 9.81 * (1/6) = 1.635 [m/s^2]

w = weight = [N]

w = 86 * 1.635

w = 140.61 [N]
