There's one force whose effects are so deeply entrenched in our everyday lives that we probably don't think much about it at all: gravity. Gravity is the force that causes attraction between masses. It's why when you drop a pen, it falls to the ground. But because gravitational force is proportional to the mass of the object, only large objects like planets create tangible attractions. This is why the study of gravity traditionally focused on massive objects like planets.
