HP Cycle 4

We've already learned about the equations that DEFINE average velocity and average acceleration. Today, we'll start to use our mathematical definitions to solve problems in "It's Your Lucky Day" Packet (aka Tesla Problem).  Here are the goals for work in this packet:

• Learn how to manipulate the definitions of average velocity and average acceleration in order to derive other kinematics equations.

• Learn the expectations for communicating solutions to kinematics problems:

  • diagram/graph

  • sign convention

  • listing of knowns & unknowns

  • stating equation

  • using algebra to find an expression for the unknown in terms of all the knowns

  • solving the problem with numbers

In class, we'll try to do #1-3.  

Handouts: "It's Your Lucky Day" Packet

Homework: Make sure you've completed #1-3 on "It's Your Lucky Day" Packet.  See my solutions below.  (The solutions below are for an older problem, so the numbers are different, but the solutions are the same.)

🟩 5: W 9/27 - kinematic equations - 2 objects

Today, I'll take any questions on the "It's Your Lucky Day" Packet.   Then, we'll talk about how to do #4 from  "It's Your Lucky Day" Packet.  We'll talk about the "equations of motion" (aka kinematic equations) that you have derived as part of this packet, and learn how to use equations of motion to solve problems with more than one object.  We'll use this Equations of Motion Graphic Organizer to identify the correct equation to use for any given problem.

Homework:   Complete "Which Equation Should I Use" assignment in ✏️ Google Classroom, due Thursday at 10pm.
