At first our actions are all we know. Then comes the world. We find out gradually through our senses. Progress is initially slow. Procedure involves taking all that happens into account. It may be that natural movements are different from our own.
How the Physical Science of Movement Motions Materials Matter Mass Develops from Ancient World Civilisations to the Renaissance
Galileo’s experiments provide insight into acceleration to the Earth. This is a movement that occurs naturally. All masses accelerate at the same rate and develop momentum differently. For Newton an apple falling to the ground is like the moon moving around the earth or a planet around the sun. All masses and motions come into this description. This procedure provides a way of arriving at the energy changes through how masses move.
