Mass is a quality of matter (apparently a construct of the Higgs field, but that's probably a little more answer than you were looking for). Weight is mass acted on by gravity.
Mass is usually stated in units of kilograms. Weight can also be stated in kilograms, but is sometimes expressed in newtons.
The mass stays constant, while the weight can change. If you are 90 kg, then on the moon your mass would still be 90 kg, but your weight would be one sixth of that, 15 kg. Weight is the force of attraction exerted on you by the moon or the earth, whichever you happen to be standing on.
In science and engineering mass is described in kilograms, while weight (force) is measured in Newtons which goes back to Newton's second law of motion: force equals mass times the rate of change of momentum. In most cases that can be simplified to force equals mass times acceleration.
A force of 1 Newton causes a 1 kg mass in free motion to increase its speed by 1 meter per second every second.
In practice on the earth's surface a 1 kg mass has a weight of 9.81 Newtons, but in everyday language we say its weight is 1 kg because that works for everyone who is not an astronaut :).

The reason a ship floats is because?
the weight of the water displaced by the ship is equal to the weight of the ship itself. This phenomenon, known as buoyancy, allows the ship to stay afloat.
How can large ships float in water?
Large ships float in water because of buoyancy, which is an upward force exerted by a fluid that opposes the weight of an immersed object. Ships are designed to displace a volume of water equal to their weight, allowing them to float. By distributing the weight of the ship evenly and displacing enough water, the buoyant force keeps the ship afloat.
Why is ship floating on the water but it is made of metal?
Ships float on the water due to a principle called buoyancy, which states that the weight of the water displaced by the ship is equal to the weight of the ship itself. The metal used in ship construction is designed to be lightweight and shaped in a way that distributes the weight so the ship can displace enough water to float.
How can a large ship float in water?
A large ship can float in water due to the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, allowing it to stay afloat. The shape of the ship's hull and the distribution of weight also play a role in helping it float.
When aship floats on water?
A ship floats on water when the weight of the water it displaces is equal to the weight of the ship. This is known as Archimedes' principle. The buoyant force exerted by the water helps to keep the ship afloat.

What is a brake in a relationship?
it is a small time period that you and the person in your relation ship stop and think about how your relation ship is going then you decide if you want to keep your relation ship or not. it is the time to think about your relation ship basically.
