Have you ever ever puzzled how a lot a kilogram weighs? It is a frequent query, and the reply is definitely fairly attention-grabbing. A kilogram is a unit of mass, and it’s outlined because the mass of a selected platinum-iridium cylinder that’s stored on the Worldwide Bureau of Weights and Measures (BIPM) in France. This cylinder is named the worldwide prototype kilogram (IPK), and it has been the usual for mass since 1889.
The IPK is made from a platinum-iridium alloy, which may be very onerous and sturdy. It’s also very secure, that means that its mass doesn’t change over time. This makes it a really perfect materials for the standard. The IPK is stored in a vault on the BIPM, and it is just taken out for infrequent comparisons with different kilograms.
Now that we all know what a kilogram is, we will speak about how a lot it weighs. The IPK has a mass of precisely one kilogram. Which means that in case you have an object that weighs one kilogram, it has the identical mass because the IPK. Nevertheless, the burden of an object can change relying on the drive of gravity. For instance, an object that weighs one kilogram on Earth would weigh much less on the moon as a result of the moon’s gravity is weaker.

Weight of object varies with gravity
The burden of an object is the drive of gravity performing on that object. The higher the mass of an object, the higher its weight. Nevertheless, the burden of an object also can differ relying on the energy of gravity. For instance, an object that weighs one kilogram on Earth would weigh much less on the moon as a result of the moon’s gravity is weaker than Earth’s gravity.
The system for weight is:
W = m * g
* W is weight in newtons * m is mass in kilograms * g is the acceleration as a consequence of gravity in meters per second squared
The acceleration as a consequence of gravity on Earth is roughly 9.8 meters per second squared. Which means that an object that weighs one kilogram on Earth has a weight of 9.8 newtons.
The acceleration as a consequence of gravity on the moon is roughly 1.6 meters per second squared. Which means that an object that weighs one kilogram on Earth would weigh just one.6 newtons on the moon.
The burden of an object varies with gravity as a result of gravity is a drive that pulls objects in the direction of one another. The higher the drive of gravity, the higher the burden of an object. That is why objects weigh much less on the moon than they do on Earth.
1 kilogram on Earth is much less on moon
An object that weighs one kilogram on Earth would weigh much less on the moon. It is because the moon’s gravity is weaker than Earth’s gravity. The acceleration as a consequence of gravity on Earth is roughly 9.8 meters per second squared, whereas the acceleration as a consequence of gravity on the moon is roughly 1.6 meters per second squared.
The system for weight is:
W = m * g
* W is weight in newtons * m is mass in kilograms * g is the acceleration as a consequence of gravity in meters per second squared
If we plug within the values for the mass of an object (1 kilogram) and the acceleration as a consequence of gravity on Earth (9.8 meters per second squared), we get the next:
W = 1 kg * 9.8 m/s^2 = 9.8 N
Which means that an object that weighs one kilogram on Earth has a weight of 9.8 newtons.
If we plug within the values for the mass of an object (1 kilogram) and the acceleration as a consequence of gravity on the moon (1.6 meters per second squared), we get the next:
W = 1 kg * 1.6 m/s^2 = 1.6 N
Which means that an object that weighs one kilogram on Earth would weigh just one.6 newtons on the moon.
Due to this fact, an object that weighs one kilogram on Earth would weigh much less on the moon as a result of the moon’s gravity is weaker than Earth’s gravity.
