Aristotle and Motion • All motion is linear • All motion in the heavens (outer space) is curved • The speed at which an object falls is directly related to the mass of an object • Motion could be considered in two main factions: natural and violent • Motion continues so long as there is only an applied motion to an object. Removing the motion stops the object.

Projectile Motion “I now propose to set forth those properties which belong to a body whose motion is compounded of two other motions, namely, one uniform and one naturally accelerated” Galileo(1638) – Dialogue Concerning Two New Sciences
Projectile Motion What is Galileo showing in this drawing?
Projectile Motion Gravity accelerates objects downward, but is unable to effect the horizontal motion of a projectile.

Monkey Hunter The zookeeper feeds the monkey by shooting bananas to the monkey. The monkey has a habit of dropping from the tree the moment that the banana leaves the muzzle of the cannon. The zookeeper is faced with the dilemma of where to aim the banana cannon in order to hit the monkey.
Monkey Hunter throw above the monkey’s head
Projectile Motion Galileo had answered the question in 1638
Projectile Motion Let’s see what a graph can tell us….
Projectile Motion Graph of d vs. t d t
Projectile Motion …with constant velocity…d = vot d t
If initial velocity is zero, this amount is… Projectile Motion d d = - 1/2 at2 t
Put them together and get… Projectile Motion d t
Put them together and get… Projectile Motion d d = vot - 1/2at2 t
if the monkey and banana have equal acceleration… Projectile Motion d they meet if you aim at the monkey t
Monkey Hunter throw at the monkey with a large velocity
Monkey Hunter throw at the monkey with a small velocity
