I was wondering if it is possible to calculate the mass of an object (what is commonly referred to as weight) if you know how long it takes to move from point A to point B (on earth).

For example, if I take a barbell and put weights on it and lift it from the floor to above my head, is there a way I can use a calculation to confirm how much weight I just lifted.

I know that mass = force/ acceleration but what if I don't know the force? Since I am lifting upward can gravity be used somehow to determine the force since gravity is a constant (well sort of)? Hopefully this makes sense [
