Topic 3 – Motion in Two Dimensions

Goal: Students will manipulate multiple vector quantities to find resultants geometrically and by using the component method.   Students will also calculate the displacement, velocity, and acceleration for objects experiencing two-dimensional motion, particularly as a projectile.  Lastly, students will identify frames of reference to describe and calculate relative velocities.

Objectives:

• Define displacement, velocity, and acceleration in two dimensions

• Describe velocity components of an object undergoing projectile motion.  Recognize that horizontal and vertical motions are completely independent of each other.  Apply the kinematics equations for constant acceleration due to gravity to analyze the motion of a projectile in two dimensions.

• Define frames of reference.  Apply the necessary rules to solve problems involving relative velocities.
