What did Newton understand that was such a revolution? Can someone just... explain gravity to me? Let's start with a ...

For example, the gravitational field strength ... the mass of an object is constant but its weight depends on the gravitational force. If you travelled to another planet, it's not just extra ...

This means that for each kg of mass, an object will experience 9.8 N of force. Where there is a weaker gravitational field, the weight of an object is smaller. For example, the gravitational field ...

As gravitational force fundamentally involves the warping of space-time itself, it enables all objects to interact with each ...

For example, pictures of galaxies that include ... Previously, physicists had assumed that the attractive force of gravity would slow down the expansion of the universe over time.
