A block of iron is transported to the moon . Which of the following is true

1) Both its mass and weight remain unchanged.
2)Its mass remains the same, but its weight decreases
3)both its mass and weight decreases
4)Its mass decreses, but it weights remain the same

It would be 2)Its mass remains the same, but its weight decreases, because the iron does not change form, but the iron is lighter.

rth

The correct answer is 2) Its mass remains the same, but its weight decreases.

Mass refers to the amount of matter an object contains, and it remains constant regardless of location. Weight, on the other hand, is the force exerted on an object due to gravity, and it can vary depending on the strength of the gravitational field.

Since the moon has a weaker gravitational field compared to Earth, the force exerted on the block of iron is reduced. Therefore, its weight decreases while its mass remains the same.

When a block of iron is transported to the moon, its mass remains the same, but its weight decreases. The reason for this is that mass refers to the amount of matter an object contains, while weight is the force of gravity acting on an object's mass.

To understand this concept, let's look at the definitions of mass and weight:
- Mass: The amount of matter contained in an object. It is a fundamental property of an object and does not change based on its location.
- Weight: The force exerted by gravity on an object's mass. Weight depends on the gravitational pull acting on an object, which varies with location.

On Earth, the force of gravity is stronger than on the moon. Therefore, an object on the moon experiences a weaker gravitational pull compared to Earth. This leads to a decrease in the object's weight, while its mass remains the same because the amount of matter in the object has not changed.

Hence, the correct answer is option 2) Its mass remains the same, but its weight decreases.
