How do the ideas of Aristotle and Galileo on vertical motion, horizontal motion, and projectile motion differ?
Answers
Answer:
Aristotle
i. He believed that all objects have resting places which they naturally seek.
ii. On Earth all motion is linear. In the outer space all motion is curved.
iii. The speed of a falling object is directly related to its mass.
iv. An object continues to be in motion as long as force is applied to it. The object stops when the force is removed.
Vertical motion - The element Earth moves down towards its natural resting place. Air rises to its natural place in the atmosphere. Fire leaps upwards to it natural place above the atmosphere. Water's natural place is just above the Earth.
Horizontal motion - Bodies need to be pushed or pulled to maintain horizontal motion.
Projectile motion - An object is influenced by the downward force of gravity.
Galileo
Vertical motion - If two objects of different weight are dropped from a height both of them will hit the ground at the same time.
Horizontal motion - If there is no interference, a moving object will keep moving in a straight line forever. There is no need to push, pull or apply force of any kind. For example, a ball rolling on a horizontal plane would neither speed up nor slow down. It would finally come to rest because of friction. He developed the idea of inertial which is the property of an object to resist changes in motion.
Projectile motion - Projectiles follow a curved path. According to Galileo projectile motion could be understood by analyzing the horizontal and vertical components separately.
