Question

The moon has a mass of 7.36 10^{22} kg and
moves about the earth in a circular orbit of radius
3.80 10^{8} m with a period of 27.3 days. Find
the moon's kinetic energy as observed on earth.

(b) Would the moon's kinetic energy be the same from the sun's
reference frame?

Answer #1

The moon is an Earth satellite of mass 9.35 x 1022
kg, whose average distance from the centre of Earth is 4.85 x
108 m.
What is the gravitational potential energy of the moon with
respect to Earth?
What is the kinetic energy and the velocity of the moon in
Earth's orbit?
What is the binding energy of the moon to Earth?
What is the total mechanical energy of the moon in its
orbit?

3. The Moon orbits the Earth every 27.3 days with a near
circular orbit of 385,000 km. What is the mass of the Earth based
on this information? What is the kinetic energy of the moon? (mass
of the Moon = 7.35 x 1022 kg) What is the potential
energy of the moon? What is the acceleration due to gravity
(towards the Earth) at the distance of the Moon?

Moon effect. Some people believe that the Moon controls
their activities. If the Moon moves from being directly on the
opposite side of Earth from you to being directly overhead, by what
percentage does (a) the Moon's gravitational pull
on you increase and (b) your weight (as measured
on a scale) decrease? Assume that the Earth–Moon (center-to-center)
distance is 3.82 × 108 m, Earth's radius is 6.37 ×
106 m, Moon's mass is 7.36 × 1022 kg, and
Earth's mass...

A spacecraft of 150 kg mass is in a circular orbit about the
Earth at a height h = 5RE.
(a) What is the period of the spacecraft's orbit about the
Earth?
T = answer in hours
(b) What is the spacecraft's kinetic energy?
K = Units in J
(c) Express the angular momentum L of the spacecraft about
the center of the Earth in terms of its kinetic energy K.
(Use the following as necessary: RE for the
radius...

In order better to map the surface features of the Moon, a 393
kg imaging satellite is put into circular orbit around the Moon at
an altitude of 149 km. Calculate the satellite's kinetic energy,
gravitational potential energy, and total orbital energy. The
radius and mass of the Moon are 1740 km and 7.36×1022 kg.

n order better to map the surface features of the Moon, a 311 kg
imaging satellite is put into circular orbit around the Moon at an
altitude of 133 km. Calculate the satellite's kinetic energy,
gravitational potential energy, and total orbital energy. The
radius and mass of the Moon are 1740 km and 7.36×1022 kg.

Consider a satellite (mass = 8.40 kg) in a circular orbit about
Earth. Calculate the following properties of the satellite given a
radius r of its orbit of 3.40×107 m. Find the period, kinetic
energy, angular momentum, and speed of the satelite.

Consider a satellite (mass = 6.10 kg) in a circular
orbit about Earth. Calculate the following properties of the
satellite given a radius r of its orbit of
1.40×107m. Its period:

Its speed:

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...

A satellite is placed in a circular orbit about Earth with a
radius equal to 49% the radius of the Moon's orbit. What is its
period of revolution in lunar months? (A lunar month is the period
of revolution of the Moon.)
