MODEL RELEASED. Weighing an apple. Students using a newton meter to find the weight of an apple. They are holding it over a bowl of water. Because apples float, as they lower the apple into the water its weight will appear to diminish to nothing, although its mass will remain constant. A newton meter uses a spring to measure weight, quantifying it in Newtons (N). There are 10 Newtons in a kilogram. An apple weighs approximately 1N.
