1.5 Vectors and Motion in Two Dimensions

Describe the perpendicular components of a vector.

• Vectors can be mathematically modeled as the resultant of two perpendicular components.
• Vectors can be resolved into components using a chosen coordinate system.
• Vectors can be resolved into perpendicular components using trigonometric functions and relationships. Relevant equations: sin cos tan += ab c22 2 TOPIC 1.5 Vectors and Motion 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.
