ACCELERATED MOTION


3.1 - Acceleration


3.2 - Motion with Constant AcceleratIon


  • ENGAGEMENT
  • Objectives:
  • Students will determine mathematical relationships among position, velocity, acceleration, & time and apply graphical and mathematical relationships to solve problems related to constant acceleration.

Warm-up
Draw a motion diagram for each section of the graph...

EXPLORATION

  • Motion diagram...positive and negative acceleration...

  • EXPLANATION
  • Vocabulary terms to know...
    • none

    • algebraically re-arrange the definition of average acceleration in terms of final velocity.
    • Teach students how its done, do a couple example problems.
    • show how we get constant acceleration from the Position-time graph...free fall data
    • * plot P-T graph
    • * plot v-T graph
    • * see the constant acceleration
    • kinematics equation

  • ELABORATION
  • Classwork
  • - pp 18- 21, pg 65
  • - 27-29, pg 69
  • - 88-90, pg 82
  • - pp 22 - 25, pg 67

  • Homework

  • EVALUATION
  • What do we mean by constant acceleration, give examples to support your answer.

3.3 - Free Fall
  • Objectives:
  • Students will...
    • define acceleration due to gravity
    • solve problems involving freefall
  • n order to explain the concept of acceleration due to gravity

  • Vocabulary terms to know...
    • free fall
    • acceleration due to gravity

  • WARM-UP
  • KWL - acceleration due to gravity.

  • ENGAGEMENT
    • Drop a piece of paper (uncrumbled)
    • Drop a crumble piece of paper
    • Drop a book
    • ....which falls faster? Why? Does weight have anything to do with the rate at which objects fall.

  • EXPLORATION
  • Classwork
  • - Flash Cards for ALL EQUATION & VOCABULARY TERMS.

  • - Write a one page Summary of the Concept of Free Fall
  • ...in your summary include the following...
  • * Galileo Galilei's experiment, his objective for the experiment and his conclusion.
  • * Explain what it means by acceleration due to gravity, give an example
  • * When do you treat acceleration due to gravity as positive or negative
  • * Explain what happen to the velocity and acceleration of an object as it is thrown upward, reaches the top of its flight and falls back to the person's hand.
