Grade concerns

My door is always open if you areconcerned about your grades! I will do my best to help you achieve your academic goals, but you still need to put in the work!

When is tutoring

Wed & Thurs: After school till 3:35pm WLC & before school everyday

How to reach me

Email: Madelynn.klein@guhsdaz.orgRM: K302

Ms. Klein I teach all physics on campus and have taught integrated science.

Who I am

What are we going to learn?

Subtopics in Dynamics

Circular Motion

Forces start when multiple objects interact with one another.

Forces aren't stuck in linear motion!

Multiple objects can interact in multiple dimensions whihc affects the motion.

Newton came up with 3 Laws that help dsecribe object interactions.

Different types of interactions have different names and results.

Systems and Center of Mass

Examples of Forces in 2D

Newton's 3 Laws

Types of Forces

learning about how objects move in circles based on our understanding of forces.

THROUGHOUT the unit working in multiple dimensions

2D Forces

Circular Motion

THROUGHOUT the unit studying Newton's Laws of Motion

THROUGHOUT the unit learning about specific types of interactions

working with multiple objects interacting at once

Systems and Center of mass

Types of Forces

Newton's 3 Laws

Timeline

Dynamics

Timeline: 2-3 Days

Systems

Topics include difference between objets and systems, calculating center of mass, understanding motion of the center of mass

• Determining the system
• Locating its center of mass

• Vector math
• Basic trigonometry skills

Skills that are necessary to be successful in this unit

What are we going to need?

• Algebra skills
• PEMDAS and SADMEP (inverse operations :) )
• Arithmetic skills
• Kinematic equations (last unit)

Circular Motion

"All forces share certain common characteristics when considered by observers in inertial reference frames. An observer in a reference frame can describe the motion of an object using such quantities as position, displacement, distance, velocity, speed, and acceleration." -AP Classroom

• Non-linear motion described with linear terms.
• Description of circular orbits (w/ math)
• Discussion of non-uniform orbits

Summary VIDEO

• Group Practice
• Worksheets as well as practice problems with the whole class
• Independent Practice
• Worksheets
• Quizzes

Learning Activities that I use the most

How are we going to learn?

• Labs and hands-on activities
• Labs include a formal lab write up (I will provide a template)
• Activites are 1-pagers
• Direct instruction
• Used to introduce new topics

Newton's 3 Laws

"Objects and systems have properties of inertial mass and gravitational mass that are experimentally verified to be the same and that satisfy conservation principles." "A force exerted on an object is always due to the interaction of that object with another object." -AP Classroom

• Inertia
• Force and acceleration
• Force pairs
• Applications

Circular Motion

Changing our POV Videos 10-26 for circular motion (anything before is for rotational kinematics later in the year)

Grade break down (also found on syllabus) Extra Credit is offered at my discretion

How will we be evaluated?

Newton's 3 Laws of Motion

Videos 7-16 are related to Newton's 3 Laws and their applications.

Link

Forces in 2D

Videos 35-40 focus on inclined forces and other 2D applications.

Link

Forces

"At the macroscopic level, forces can be categorized as either long-range (action-ata-distance) forces or contact forces." -AP classroom

• Weight Lab
• Spring Lab
• Atwoods/Friction Lab
• Naming all forces

• The physics
• Newton's 3 laws of motion
• Different types of forces and what they do
• Working with vectors

The second unit of AP Physics is Dynamics and it covers Newton's 3 Laws of Motion

What are we going to learn?

• How to be a physicist
• Taking measurements
• Identifying variables
• Writing procedures
• Communicating results
