Question

Calculate the force of gravity between the Earth and the Moon.
The mass of the Earth is 6.0 x 10^{24} kg and the mass of
the Moon is 7.4 x 10^{22} kg. The average distance between
the Earth and the Moon is 3.8 x 10^{8} m. (G = 6.67 x 10-11
Nm^{2}/kg^{2} **) Show your

Answer #1

Calculate, using Newton's law of gravity, the size of the force
of attraction between the earth and a mass of 2.0 kg on the earth.
Data: Distance to the center of earth from the surface = 6370 km.
Mass of earth = 5.98·1024kg. Gravitational constant G = 6.67·10-11
Nm2/kg2.
Calculate, using Newton's law of gravity, the size of the force
of attraction between the moon and a mass of 2.0 kg on the earth's
surface nearest the moon. Data: Distance...

The Earth (mass = 6.0 x 1024 kg) and the Moon (mass = 7.3 x 1022
kg) are separated by an average distance of about 3.8 x 105 km.

uring a solar eclipse, the Moon is positioned directly between
Earth and the Sun.
The masses of the Sun, Earth, and the Moon are 1.99×1030
kg,1.99×1030 kg, 5.98×1024 kg,5.98×1024 kg, and 7.36×1022
kg,7.36×1022 kg, respectively. The Moon's mean distance from Earth
is 3.84×108 m,3.84×108 m, and Earth's mean distance from the Sun is
1.50×1011 m.1.50×1011 m. The gravitational constant is G=6.67×10−11
N⋅m2/kg2.G=6.67×10−11 N·m2/kg2.
Find the magnitude FF of the net gravitational force acting on
the Moon during the solar eclipse...

1. A 0.020 kg and a 0.060 kg ball are at the two opposite ends

Compare the force of gravity due to the sun on the moon with the
force exerted by the earth on the moon. (Find the ratio.) The sun's
mass is about 3 x 105 that of the earth and is about 1.5
x 108 km from the moon whereas the earth is only 3.8 x
105km away.

On the way to the moon, the Apollo astronauts reach a point
where the Moon’s gravitational pull is stronger than that of
Earth’s. Find the distance of this point from the center of the
Earth. The masses of the Earth and the Moon are 5.98 × 1024 kg and
7.36 × 1022 kg, respectively, and the distance from the Earth to
the Moon is 3.84 × 108 m. Answer in units of m.
b) What would the acceleration of the...

The Earth has a mass
of 5.97 * 1024 kg and the Moon has a mass of 7.35 *
