If an experiment were done with a bow and arrow, when shooting the arrow what motion would it make. A diagram would be helpful. What causes the arrow to move horizontal, and what causes the arrow to move vertical? And why do the 2 motions (horizontal and vertical) cause the arrow to travel the path it takes.
