# Motion Problems

Solving motion problems using parametric and vector-valued functions.

#### Mapped to AP College Board # FUN-8, FUN-8.B, FUN-8.B.1, FUN-8.B.2

Solving an initial value problem allows us to determine an expression for the position of a particle moving in the plane. Determine values for positions and rates of change in problems involving planar motion. Derivatives can be used to determine velocity, speed, and acceleration for a particle moving along a curve in the plane defined using parametric or vector-valued functions. For a particle in planar motion over an interval of time, the definite integral of the velocity vector represents the particle’s displacement (net change in position) over the interval of time, from which we might determine its position. The definite integral of speed represents the particle’s total distance traveled over the interval of time.
