When exercising is when the lungs work the hardest because you're using a lot of muscles and are running around and are using force in your body so the lung works really hard to make sure the body gets enough air while working out.

How do the Earth and Moon compare in terms of gravitational force?

Law Incorporation [45]

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.

Option A

<u>Explanation:</u>

According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.

In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.

$F=\frac{GM}{R^{2} }$

So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.
