Objects have mass.

They exist at points in space. They bend space-time around themselves.

Space-time in turn directs their movements.

The ball will follow you.

Click to snap the ball to your cursor.

It is attracted gravitationally to your cursor.

Technically, the ball is accelerating toward your cursor at a rate inversely proportional to the square of its distance from your cursor.
