1. Forces
Day 3

2. Welcome to FPC:
Draw a free body diagram of the moment Ms. Crock’s foot kicks a soccer ball to the right. Ignore air resistance.
Remember:
Identify forces
Draw a box
Draw arrows, showing direction and size of force
Label arrows

3. Free Body Diagrams of Ms. Crock Kicking a Soccer Ball

F applied
F Friction
F gravity

6. Learning Targets
I can use data from an experiment to support the claim that Newton’s Second Law correctly describes the relationship between force, mass and acceleration

7. Colorado Phet
Get a Chromebook, a calculator and a timer Working with the person sitting next to you Follow the directions and complete as much as you can in the time remaining

8. Results
What happens to acceleration as the mass of the object increases?
Did you recognize the relationship?
What happens to acceleration as the force applied to the object increases?

9. Cornell Notes: Next Right hand Side
Topic: Newton’s Second law
Essential Question:
According to Newton’s Second Law, what is the relationship between force and acceleration AND mass and Acceleration
LEFT HAND SIDE: glue in graphs

10. Force v. Acceleration
Force and acceleration have a directly proportional relationship
Directly proportional:
As one value increases, the other increases at the same rate
Special linear relationship

11. Mass v. Acceleration
Mass and acceleration have an inversely proportional relationship
Inversely Proportional:
As one value increases, the other decreases.
The decrease is not constant

12. Newton’s Second Law The Second Law says:
The acceleration of an object is directly proportional to force, and inversely proportional mass
