Physics - Unit 3

Kinematics: Motion in Two Directions

In this unit we will expand our knowledge of kinematics by considering objects undergoing “projectile motion”. We will use trigonometry to solve for horizontal and vertical components of vectors in order to consider an object’s motion in two directions.

BY THE END OF THIS UNIT, you should be able to:

  • apply kinematic formulas to solve two dimensional motion problems

  • use trigonometry to find horizontal and vertical components of velocity

  • solve projectile motion problems
