Aristotle's Theory of Motion had 2 basic principles:-
1. No motion without a mover in contact with moving body.
2. Distinction between: (a) Natural motion: mover is internal to moving body (b) Forced motion: mover is external to moving body
Aristotle believed that the initial motive force transfers to the medium initially surrounding the object a "power" to act as a motive force. and the Medium then forces the object into a new region, which is then imparted with the "power" to act.
Aristotle's concept of different types of motion was destroyed when he described the projectile motion as a combination of horizontal and vertical motion and in the same terms and with the same relationships.
An Aristotelian proposal that heavier objects fall at the same rate was proved false by the only plausible Galilean explanation that all objects fall at the same rate. Galileo correctly measured motion in two independent directions (horizontal and vertical) and deduced that the “rate of fall” is better measured in terms of downward acceleration.
According to Galileo, a projectile which is carried by a uniform horizontal motion compounded with a naturally accelerated vertical motion describes a path which is a semi-parabola.
