Question

How to find weight in science

Answer 1

There are several different methods, depending on the particular situation.  A few that might occasionally be useful include:

-- Read the label on the package.

-- Measure the mass and multiply by the local acceleration of gravity.

-- Measure the mass AND the local acceleration of gravity, then multiply.

-- Place the object or sample on a bathroom scale.

-- Place the object on one end of a symmetrical see-saw.  Through trial and error, determine the weight required on the other end to balance the system.
