Cannon model from: https://free3d.com/3d-model/civil-war-cannon-91660.html
#1: Anticipation: The cannon roles backwards and tilts its barrel upwards before firing
#2 Exaggeration: The cannon barrel expands after firing the cannonball, it also has a coloring the changes as it moves
#3 Arc: The cannon ball moves in an arc
#4 Slow in slow out: The movement of the cannon backwards and the barrel swinging up is slow-in slow-out.
