Let go of a ball in the air and watch what happens next.
Gravity is the invisible force pulling everything on Earth downward, including a dropped ball, which is why it always falls straight to the ground instead of floating away.
Magnetism only pulls metal objects like iron toward magnets, not rubber or plastic balls, and friction slows things down as they rub a surface, it does not pull things downward through air.
Gravity is also what keeps the Moon circling Earth and the planets orbiting the Sun, the same pull tugging your ball holds the whole solar system together.
