Gravity is the fundamental force that keeps your feet on the ground and planets in orbit. But how does this invisible force actually work? Is it a 'pull' or something more complex?
What Goes Up Must Come Down... Right?
Every single object with mass in the universe exerts a gravitational pull on every other object with mass. It might seem tiny between you and your phone, but it's immense between Earth and the Moon!
Your Gravitational Footprint
Even you have a gravitational pull! If you weigh about 70 kg, and you stand 6 371 000 m from the center of the Earth, the gravitational force pulling you down is 6,67 N. This force is what gives you weight!

Notice how even a small change in distance or mass can subtly shift the gravitational force. It's a precise, measurable interaction happening everywhere, all the time.
