Considering the definition of weight, on Earth's surface at sea level, the weight of an object with a mass of 180 kg is 1764 N.

What is weight

Mass is the amount of matter that a body contains and weight is the action exerted by the force of gravity on the body.

The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

The weight is calculated as the product of the mass of the object and the value of the gravitational acceleration or gravity:

Weight= mass× gravity

The value of the acceleration constant on Earth is 9.8 m/s². The weight is proportional to the mass of the object. The unit of weight is expressed in Newton (N).

Weight of the object in this case

In this case, you know:

  • mass= 180 kg
  • gravity= 9.8 m/s²

Replacing on the definition of weight:

Weight= 180 kg× 9.8 m/s²

Solving:

Weight= 1764 N

Finally, on Earth's surface at sea level, the weight of an object with a mass of 180 kg is 1764 N.
