What is moon formula?

The Moon m = W g. W = 120 N. g = gravitational field strength g = 1.6 N/kg. m = 120 N ÷ 1.6 N/kg.

What is the radius of the Moon in KG?

The mass and radius of the moon are 7.4×1022 7.4 × 10 22 kg and 1.7×106 1.7 × 10 6 m, respectively.

What is diameter of the Moon?

Size: With a diameter of 2,159 miles (3,475 kilometers), the Moon is just 1/4 the size of Earth. Distance from Earth: The Moon’s average distance from Earth is 238,000 miles (383,500 km).

What is radius of moon Class 9?

The mass of the moon is 7.34×1022kg and the radius is 1.74 ×106m.

What is the main radius of the Moon?

The moon’s mean radius is 1,079.6 miles (1,737.5 kilometers) and the mean diameter is 2,159.2 miles (3,475 km). Compared to Earth, the moon is less than a third the width of our home planet, according to NASA (opens in new tab).

What is a moon in physics?

A moon is an object that orbits a planet or something else that is not a star. Besides planets, moons can circle dwarf planets, large asteroids, and other bodies. Objects that orbit other objects are also called satellites, so moons are sometimes called natural satellites.

What is moon Class 8?

The moon completes one rotation on its axis as it completes one revolution around the earth. The moon has dusty and barren surface with craters, steep and high mountains. The moon has no atmosphere and no water. On July 21, 1969 (Indian time), Neil Armstrong landed on the moon for the first time.

What is the weight of moon Class 9?

The mass of the moon is 1100 times and its radius 14 times that of the earth. As a result, the gravitational attraction on the moon is about one sixth when compared to that on the earth. Hence, the weight of an object on the moon is 16 th of the weight on the earth.

What is the radius of the smallest moon?

With a mean radius of 6.2 miles (10 kilometers), assuming an albedo of 0.04, Leda is the smallest moon in the Himalia group, a family of Jovian satellites which have similar orbits and appearance, and are therefore thought to have a common origin.

What is 70 kg on the moon?

How much does a 70 kg astronaut weigh on the moon? The value of g on the lunar surface is 1,6 m/s². With this value, the weight of an astronaut with a mass of 70 kg, for example, would be only 112 newtons when he was on the Moon. On Earth, the same astronaut weighs almost 700 newtons.

How many Newtons is 10 kg on the moon?

Answer and Explanation: Answer: Weight of a 10-kg object on moon is 16.33 N.

What is the volume of the Moon?

The volume of the Moon is about 21.9 billion cubic kilometers. Does that sound like a lot? For comparison, the volume of the Earth is 1 trillion cubic kilometers.

What is radius of the Sun?

What is the gravity of the Moon?

The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s2, about 16.6% that on Earth’s surface or 0.166 ɡ. Over the entire surface, the variation in gravitational acceleration is about 0.0253 m/s2 (1.6% of the acceleration due to gravity).

What is the radius of Earth Class 9 physics?

The radius of the earth is about 6370 km.

What is a radius Class 9?

The radius of a circle is the length of the line from the centre to any point on its edge. It can also be defined as, the distance from the centre of the circle to any point on the circle is called the radius.

What is Full Moon Class 7?

Full Moon: When the moon appears as a full disc, the entire side facing us is lit up and is called Full Moon.

Why the Moon takes 27.3 days to orbit the Earth and yet there are 29.5 days from one full moon to the next?

It takes the Moon 27.3 days to make a complete orbit around the Earth, but because the Earth is moving around the sun at the same time, it takes the moon 29.5 days to go through its eight different ‘phases’ – a lunar month.

Why does the Moon orbit 27.3 days?

It takes 29.5 days to go from one full moon to the next. Have you noticed this is slightly longer than the time it takes to orbit the Earth? This is because the Earth is moving around the Sun. The Moon has to travel a bit further to get back to the same position.

How do you calculate orbital radius?

Kepler’s Third law can be used to determine the orbital radius of the planet if the mass of the orbiting star is known (R3=T2−Mstar/Msun, the radius is in AU and the period is in earth years).

What takes 27.3 days on the Moon?

Q. The moon takes about 27.3 days to revolve round the earth in a nearly circular orbit of radius 3.84×105 km.
