Topic 1.5: Vectors and Motion in Two Dimensions

Learning Objective: 1.5.A

Describe the perpendicular components of a vector.

Essential Knowledge: 1.5.A.1

Vectors can be mathematically modeled as the resultant of two perpendicular components.

Essential Knowledge: 1.5.A.2

Vectors can be resolved into components using a chosen coordinate system.

Essential Knowledge: 1.5.A.3

Vectors can be resolved into perpendicular components using trigonometric functions and relationships. Relevant equations: sin⁡θ=ac\sin\theta = \frac{a}{c}; cos⁡θ=bc\cos\theta = \frac{b}{c}; tan⁡θ=ab\tan\theta = \frac{a}{b}; a2+b2=c2a^{2} + b^{2} = c^{2}

Learning Objective: 1.5.B

Describe the motion of an object moving in two dimensions.

Essential Knowledge: 1.5.B.1

Motion in two dimensions can be analyzed using one-dimensional kinematic relationships if the motion is separated into components.

Essential Knowledge: 1.5.B.2

Projectile motion is a special case of two-dimensional motion that has zero acceleration in one dimension and constant, nonzero acceleration in the second dimension.
