1. Welcome to Physics
Forces

2. Warm Up: Turn to Page 48
The free body diagram shows the forces acting on a car driving down Central St towards Burr
Identify if the forces are balanced or unbalanced in each direction
What is the net force on the car?
Is the car accelerating or moving at a constant velocity
Fnorm= 10,000 N
Fgrav = 10,000 N
Ffrict = 450 N
Fapp= 500 N
Fair = 50 N

3. Agenda: summarize in planner
Computer Simulation: Newton’s 2nd Law Pop Quiz: free body diagrams and net force

4. Learning Targets
I can use data to support the claim that Newton’s 2nd Law correctly describes the relationship between force, mass and acceleration.
I can use a free body diagram to visually represent the forces acting on an object
I can use a free body diagram to calculate the net force on an object.

Checkpoint 4
The person that you are sitting next to (shoulder partner) is who you will be working with Get one chromebook for the both of you Need ONE timer or phone (stopwatch) and a ruler and calculator for each person Follow the directions and answer the questions. WHEN DONE: google: physics classroom egg drop interactive play around with the interactive looking at how the velocity, force and acceleration change. 30 minutes

7. Pop Quiz
Checkpoint 4
Clear everything off of your desk except something to write with and a calculator No talking Answer every question to the best of your ability THIS WILL NOT COUNT AGAINST YOUR GRADE SO TAKE A RISK! 15 minutes

8. Clean Up
Lab supplies put away Table supplies returned to box Name tags turned in Work turned in Notebooks in backpack Scrapes recycled Stay in your seat until the bell rings
