Force are at work all around us. They provide the push that gets things moving, but also include friction, the force that slows them down. They can make a jumbo jet hurtle down a runway and into the skies, or pull a snowflake towards the ground. Forces can also make things change direction, and they can stretch, squash and bend them out of shape. We cannot see forces themselves, but we can see and feel what they do.
How does gravity work?
We know what gravity feels like, but it is still a mysterious force.Everything in the Universe, even your own body, attracts other objects toward it. When you stand on the ground, the Earth attracts your body and your body attract the Earth. Because the Earth is so huge, its gravitational pull keeps you on the ground.
