Question

10 of 25
a person weighs more on the earth than on the moon because the earth has a greater-
a magnetic pull
b density
c atmospheric pressure
d gravitational pull

Explanation:

Step1: Understand weight formula

Weight \( W = mg\) (where \(m\) is mass, \(g\) is gravitational acceleration).

Step2: Analyze Earth and moon's gravity

Earth has stronger gravitational pull (\(g_{Earth}\approx9.8m/s^{2}\)) than moon (\(g_{moon}\approx1.62m/s^{2}\)). Mass \(m\) of person is same. Since \(W = mg\), greater \(g\) (gravitational pull) gives more weight.

Step3: Eliminate other options

• Magnetic pull (A) not related to weight.
• Density (B) of Earth vs moon not directly cause of weight difference.
• Atmospheric pressure (C) not main factor for weight difference here.

Answer:

D. gravitational pull
