He noted that an external force is not necessary to maintain horizontal motion.
Galileo Galilei
It is known as a VIOLENT MOTION.
Horizontal Motion
A heavy object will fall faster than a light object.
Aristotle
True or False: A 50-lb block and a 5-lb ball will fall from the same height at the same time considering a normal environment.
False
Based on Aristotle’s idea, what is lost when a projectile stops moving horizontally and starts falling directly to the ground?
Impetus
What is natural motion?
The object will move and will return to its natural state based on on object's natural material or composition - earth, water, air, and fire.
Differentiate Aristotle and Galileo views of vertical motion (Weight).
Aristotle says that the heavier things are, the quicker they will fall, whereas Galileo different masses thrown at the same time and height will reach the ground at the same time in the absence of air resistance.
