What is the force of gravity acting on an apple weighing 120 g?

Given:

m = 120 grams – apple mass;

g = 9.8 Newton / kilogram – acceleration of gravity.

It is required to determine which force of gravity F gravity (Newton) acts on the apple.

Let’s convert units of mass into SI system (from grams to kilograms):

m = 120 grams = 120 * 0.001 = 0.12 kilograms.

Then the force of gravity will be equal to:

F gravity = m * g = 0.12 * 9.8 = 1.18 Newton.

Answer: gravity acts on the apple, equal to 1.18 Newton.
