Motion, Forces, and Energy in More Than One Dimension
... motion was purely vertical. Such motion results when the initial velocity of the object has no horizontal component. Gravity is a purely vertical force resulting in a constant vertical acceleration; as we just argued, a vertical acceleration can only produce changes in the vertical component of velo ...
