Why the weight of a body is less at the moon than its weight on the Earth?

Why the weight of a body is less at the moon than its weight on the Earth?

Density is a measure of how much mass is concentrated in a given space. Sir Isaac Newton discovered that as an object’s mass increases, the gravitational attraction of that object increases. Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.

Why the weight of a body decreases with increase in distance from the Earth’s surface?

Weight of a body is the force experienced by the body due to gravity. The weight of a body decreases with increase in distance from the earth ‘s surface because weight is inversely proportional to the distance of body from the surface of earth.

Will you weight remain constant as you go above the surface of the Earth?

No, our weight will not remain constant if we move away from the surface of the earth . Weight is the product of mass and gravitational acceleration. thus , weight decreases as we move away from the surface of the earth .

Why does a coin fall faster than a feather?

Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters. Since the feather is so much lighter than the coin, the air resistance on it very quickly builds up to equal the pull of gravity.

Why does something weigh less on the Moon than on the Earth quizlet?

The Moon has less mass than the Earth, so its gravity is less than the Earth’s gravity. This means that objects weigh less on the Moon than they do on the Earth. The Moon’s gravity is one sixth of the Earth’s gravity.

Why does weight change on the Moon?

It is also defined as the force of gravity acting on the object. Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.

Why does the weight of an object decreases with the increase of height?

This is the acceleration due to gravity at a height above the earth’s surface. According to the above formula, the value of g decreases with increasing height of an object and becomes zero at infinite distance from the earth.

What happens to the gravitational force when the distance is halved?

When distance between objects is halved, gravitational force becomes four times.

Why do you weigh less at higher altitudes?

Weight is the gravitational force experienced on a body. If you move up to higher altitudes, the distance between you and earth increases. Since gravitational force is inversely proportional to distance multiplied by itself, the gravitational force exerted on your body decreases and so you weigh less.

Why do you weigh less on a mountain than at sea level?

Travelling away from Earth As you travel away from the Earth’s surface, your mass stays the same but your weight reduces as gravitational pull decreases. But generally speaking, gravitational pull, and therefore weight, is lower on a mountain than at sea level, says Bell.

What happens to mining when it is no longer profitable?

Mining eventually depletes the metal-rich material that could be economically removed at a specific mine. When mining can no longer be profitably conducted, the mine and related facilities used in beneficiation or smelting will be closed.

Is weight lower on mountains than at sea level?

But generally speaking, gravitational pull, and therefore weight, is lower on a mountain than at sea level, says Bell. So, what would happen to gravitational pull if you travelled below that the Earth’s surface towards the centre?

Why is it so difficult to find and remove landmines?

The muddy areas and marshes are particularly difficult to deal with as it is often impossible to stand in the mud. Another challenges come from the type of landmines as there are hundreds of landmine types. Mines can have metal, plastic, wood, or even football casings.

What are land mines and why are they dangerous?

Land mines are planted in fields, forests, around wells, water sources, and hydroelectric installations, making these unusable, or usable only at great risk. Both Afghanistan and Cambodia could double their agricultural production if land mines were eliminated.
