  1.  Physics - Ms. Kohler Warm up: Draw the resultant velocity vector for the two vectors below, solve for its magnitude. Date: 8/2/2018 Unit 1: Kinematics Learning Goal:  Analyze relationships between forces and motion. 13m/s 6m/s No, you DO NOT have a reflection today.

  2.  Physics - Ms. Kohler Trigonometry Review Date: 8/2/2018 Unit 1: Kinematics Learning Goal:  Analyze relationships between forces and motion.

  3.  Physics - Ms. Kohler Trigonometry Review In a right triangle, the ratios of the lengths of the sides will be a function of the angles, and vice-versa. Trigonometry (from “trig” = “triangle” and “ometry” = “measurement”) is the study of these relationships. Date: 8/2/2018 Unit 1: Kinematics Learning Goal:  Analyze relationships between forces and motion.

  4.  Physics - Ms. Kohler Trigonometry Review These same trig. identities can help us solve for the unknown angle θ (theta) when we use their inverse functions. For example: Θ=sin-1(O/H) Θ=cos-1(A/H) Θ=tan-1(O/A) Date: 8/2/2018 Unit 1: Kinematics Learning Goal:  Analyze relationships between forces and motion. Use one of the three functions on the left to solve for the unknown angle θ.

  5.  Physics - Ms. Kohler Trigonometry and Displacement Vectors 1) Wendy walks 15 meters west, away from her home before turning and walking 20 meters north to get to her mailbox. Draw the 2 initial vectors and the resultant displacement vector. Solve for the magnitude and direction of Wendy’s displacement. Date: 8/2/2018 Unit 1: Kinematics Learning Goal:  Analyze relationships between forces and motion. 2) A car drives north for 500 meters before turning to drive to the west for 750 meters. Draw the 2 initial vectors and the resulting displacement vector, solve for its magnitude and direction.
