Have you ever ever questioned how a lot a kilogram weighs? It is a widespread query, and the reply is definitely fairly fascinating. A kilogram is a unit of mass, and it’s outlined because the mass of a particular platinum-iridium cylinder that’s saved 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 product of a platinum-iridium alloy, which could be very onerous and sturdy. Additionally it is very secure, which means that its mass doesn’t change over time. This makes it a perfect materials for the standard. The IPK is saved in a vault on the BIPM, and it’s only taken out for infrequent comparisons with different kilograms.
Now that we all know what a kilogram is, we will discuss how a lot it weighs. The IPK has a mass of precisely one kilogram. Because of this when you have an object that weighs one kilogram, it has the identical mass because the IPK. Nonetheless, the burden of an object can change relying on the power 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 load of an object is the power of gravity performing on that object. The higher the mass of an object, the higher its weight. Nonetheless, the burden of an object can even range relying on the power 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 method for weight is:
W = m * g
* W is weight in newtons * m is mass in kilograms * g is the acceleration as a result of gravity in meters per second squared
The acceleration as a result of gravity on Earth is roughly 9.8 meters per second squared. Because of this an object that weighs one kilogram on Earth has a weight of 9.8 newtons.
The acceleration as a result of gravity on the moon is roughly 1.6 meters per second squared. Because of this an object that weighs one kilogram on Earth would weigh just one.6 newtons on the moon.
The load of an object varies with gravity as a result of gravity is a power that pulls objects in direction of one another. The higher the power of gravity, the higher the burden of an object. This is the reason 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’s because the moon’s gravity is weaker than Earth’s gravity. The acceleration as a result of gravity on Earth is roughly 9.8 meters per second squared, whereas the acceleration as a result of gravity on the moon is roughly 1.6 meters per second squared.
The method for weight is:
W = m * g
* W is weight in newtons * m is mass in kilograms * g is the acceleration as a result 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 result 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
Because of this 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 result 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
Because of this an object that weighs one kilogram on Earth would weigh just one.6 newtons on the moon.
Subsequently, 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.
