Unit 2 - Constant Velocity Model
This is a unit designed around chapters 2. The first 3 chapters make up motion in 1 and 2 dimension along with the vectors concepts. The AP exam always has a part of short answer related to these chapters. There are very few straight up vector questions; however, vectors are critical in the understanding of physics. The next 2 chapters (5-6) are Newton's Law of Motion. The first five chapters always comprise an extended response question on the AP exam. Approximately 6 weeks are given for these topics.
AP Objectives
Unit 2
Big Idea 3: The interactions of an object with other object can be described by forces.
Essential Knowledge 3.A.1: An observer in a particular reference frame can describe the motion of an object using such quantities as position, displacement, distance, velocity, speed and acceleration.
a. Displacement, velocity and acceleration are all vector quantities.
b. Displacement is change in position. Velocity is the rate of change of position with time. Acceleration is the rate of change of velocity with time. Changes in each property are expressed by subtracting initial values from final values.
c. A choice of reference frame determines the direction and magnitude of each of theses quantities.
Learning Objectives: 3.A.1.1: The student is able to express the motion of object using narrative, mathematical and graphical representations.
- Science Practices 1.5: The student reexpress key elements of natural phenomena across multiple representations in the domain.
- Science Practices 2.1: The student can justify the selection of a mathematical routine to solve problems
- Science Practices 2.2: The student can apply mathematical routines to quantities that describe natural phenomena.
Learning Objective 3.A.1.2: The student is able to design an experimental investigation of the motion of an object.
- Science Practices 4.2: The student can design a plan for collecting data to answer a particular scientific question.
Learning Objective 3.A.1.3: The student is able to analyze experimental data describing the motion of an object and is able to express the results of the analysis using narrative, mathematical and graphical representations.
- Science Practices 5.1: The student can analyze data to identify patterns or relationship.
