Is weight be used interchangeably with force?
I don’t mean that I want to use these words in place of each other but if I need to find the force exerted by something (ex. a brick) could I measure it’s weight and would that measurement be equal to the force

Basically does weight=force (I understand it’s not the same vice versa)

answers:
Jeffrey K say: Weight is a force. W = mg
The force of a brick sitting on a table is its weight, mg.

CarolOklaNola say: No. The weight of something is determined by the mass. The force of the acceleration of gravity cha he's, but mass can remain constant. A mass of 6 kilograms weighs 6 Newtons on Earth but has a weight of 1 Newton on the Moon. The mass of the object has not changed. The force of gravity has changed. Gravity is one kind of force. Torque is another kind of force. Weight is not a force. Weight and force are not interchangeable.

Yes, it is confusing. An engineer like Bill Bye can probably be plain it a lot better than I can, or Carl Sagan, but Sagan is dead.

Andrew Smith say: Weight is one example of A force. Note that the force is NOT the mass. It is the force of gravity upon that mass.
In other words if you took a 1kg mass to a different place or planet or outer space then the weight would differ but the mass would not. It would remain 1kg but the force on it would vary.

Most importantly to use weight as a force you need to remember that there is a force acting UPON something.
You cannot say that the weight is equal to the force without completing the statement.

The weight is equal to the force of gravity upon the object.
The weight is equal to the force of the object on a non accelerating surface.
The weight is NOT equal to the force of the object on an accelerating surface such as an elevator.

As you say in the question, there are also many forces that are not weight.
So all weight is a type of force but not all force is a type of weight.

Adam D say: Weight is the force an object exerts because of gravity. So in the case of an object sitting on a surface, the weight is the force the object exerts on the surface.
