1.5.B—Describe the motion of an object moving in two dimensions

Describe the motion of an object moving in two dimensions.

• Motion in two dimensions can be analyzed using one-dimensional kinematic relationships if the motion is separated into components.
• Projectile motion is a special case of twodimensional motion that has zero acceleration in one dimension and constant, nonzero acceleration in the second dimension.
