Mass versus weight
It is possible to feel the difference between weight and mass by suspending an object with a mass of over ten kilograms on a rope with a length of two or more meters. If a person pushes upwards against the underneath of the object with one finger they will feel the weight of the object. If they push momentarily against the side of the suspended object with one finger they will feel the mass of the object. (It is important that they do not push the object sideways far enough to begin to raise it.)
