Bruce uses this information to make the statement that a person's weight is the same on Earth as it is on the Moon. Is this statement true or false?
(1 point)
Responses
True
True
False
The statement is False.
Weight is the force exerted by gravity on an object and depends on the gravitational acceleration. Since the gravitational force on the Moon (1.62 m/s²) is much weaker than that on Earth (9.82 m/s²), a person's weight would be less on the Moon than on Earth.
The gravitational force on Earth is 9.82 m/s, while the gravitational force on the moon is 1.62 m/s.
