4.17 - Summary
Like any vector, velocity can be broken into its component vectors in the x and y
dimensions using trigonometry. These components sum to equal the velocity vector.
The components can also be analyzed separately, reducing a two-dimensional
problem to two separate one-dimensional problems. The same principle applies to
the acceleration vector.
Objects that move solely under the influence of gravity are called projectiles. To
analyze projectile motion, consider the motion along each dimension separately.
