The York County School Division Curriculum Guide Subject: Physics SOL REPORTING CATEGORY: UNIT# TITLE 1 Kinematics COMPONENTS Distance & Displacement Speed & Velocity Acceleration SUGGESTED TIME FRAME: 2 WEEKS QUARTER: 1 VIRGINIA STANDARDS OF LEARNING SOL PH.5 The student will investigate and understand the interrelationships among mass, distance, force and time through mathematical and experimental processes. Key concepts include: a) linear motion MEASURABLE STUDENT OBJECTIVES (ESSENTIAL KNOWLEDGE AND SKILLS) ASSESSMENTS INSTRUCTIONAL STRATEGIES: The student will be able to: Distinguish between distance and displacement Distinguish between speed and velocity. Distinguish between average and instantaneous velocity or acceleration. Qualitatively use the slope of a tangent line to determine the instantaneous velocity or acceleration.. Solve problems involving constant speed using the relationship between average speed, distance and time. Use the shape of the position vs. time or velocity vs. time graph to distinguish among these types of motion: constant Formative: Observations during group lab work: Students match graphs of position-time and velocitytime by walking in front of motion sensor. (RTP Lab 1 – Intro to Motion) Students develop general rules for signs of acceleration in terms of direction of motion and changes in speed. (RTP Lab 2 – Changing Motion) Students solve uniform acceleration problems on The teacher will: Provide examples of constant velocity motion away from and toward the origin using a motion detector to collect data. Lead class discussion of differences between position-time graphs these motions. (ILD 1 – Into to Motion) Model problem solving techniques for constant velocity problems. Model problem solving techniques for uniform acceleration problems. Lead class discussion of similarities/differences between vocabulary terms. Allow students to create examples for when distance and displacement are the same and are not the same value, when The York County School Division Curriculum Guide MEASURABLE STUDENT OBJECTIVES (ESSENTIAL KNOWLEDGE AND SKILLS) Subject: Physics ASSESSMENTS velocity, constant acceleration and whiteboards. non-constant acceleration. For uniformly accelerated motion, given the distance vs. time graph or velocity vs. time graph, use a graphing calculator or appropriate software to Summative: create a mathematical model for the motion, including units for the coefficients.** For uniformly accelerated motion, given a distance vs. time graph or velocity vs. time graph, provide a complete description of the motion, including direction of motion, sign of velocity and sign of acceleration. From a description of motion, create a distance vs. time, velocity vs. time or acceleration vs. time graph to correctly represent that motion. Use the four constant acceleration equations to solve word problems involving uniform acceleration, including freefall. INSTRUCTIONAL STRATEGIES: average velocity is not the same as average speed. After Lab 2, Changing Motion, demonstrate how the first kinematics equation ( models position-time graphs for uniformly accelerated motion and how the second kinematics equation models velocity-time graphs for uniformly accelerated motion. Use the area under a linear velocity time graph to derive the third kinematics equation. Show how the fourth kinematics equation can be obtained by mathematical manipulation. Provide examples of uniformly accelerated motion using a motion detector to collect data. Examples include speeding up and slowing down in both directions as well as turning around. Include a tossed ball as a key example to illustrate that the velocitytime graph is linear, therefore it is a valid example of constant acceleration.
