Although apples come in all different shapes, sizes, varieties and colors, the mass of an average apple is 102 grams. The mass of an apple is something that is often discussed in classrooms due to the role it played in Newton's universal law of gravitation.
Individual apples can vary in size, depending on the apple type and growing conditions, which affects mass. All apples are biologically named Malus domestica, have stems and grow on trees. However, to highlight the differences, a crabapple is small, sour and has a much smaller mass than a Golden Delicious apple, which is usually large and sweet.
