DAY 16

ESSENTIAL QUESTION:

What is motion? What factors influence how and why things move?

#Goals: SWBAT...

1. Interpret position-time graphs 

Warm-Up: (4 min)

1. Draw a position time graph in which an object starts from a zero position, and moves slowly in the positive direction

2. Draw a position time graph in which an object starts from a negative position, and moves slowly in the positive direction

3. Draw a position time graph in which an object starts from a negative position, and moves quickly in the positive direction

Classwork:

1. 016A: Practice Position-Time (P-T) DOT Graphs (15min)

    Use the Concept Builder linked below to build your skills.

    You'll complete four questions from the "Dots and Graphs" section

    For each problem, number the problem, copy the dot diagram into your notes, then copy the matching P-T Graph next to the dot diagram, and answer the question.

2. 016B: DOT Graphing - Check for Understanding:

    a. For each of these graphs, copy it, then describe the motion of the person depicted:

    b. How can you tell from the dot diagrams above that an objects velocity is changing?

3. 016C: What Does Acceleration Look Like?

    Acceleration is defined as the change in velocity, so think about the motion you see, and how the velocity is changing

    Use the Concept Builder linked below to build your skills

    You'll complete six questions from the "Apprentice" section

    For each problem, number the problem, draw the p-t diagram (the little dots, or puffs of exhaust from the car), and describe the motion shown. 

    When you're done, build your boss level skills. Try the mastery and wizard sections.

Learning at Home/HW

1. Unit Exam Friday. Scientific Notation, significant figures,rounding, safety, unit conversions. 

   1. review notes and quizzes (quiz 1 and 2 - both are available to view on schoology)

   2. review day 2 - day 8

   3. review lab safety test (link to that is here ----> LINK) Scroll down on that page for the answers

OLD STUFF BELOW- DISREGARD 

#Goals: SWBAT...

1. solve 1-D free-fall kinematics problems using the UAM equations.

2. state whether vx and vy are constant or accelerating for a projectile

Warm-Up (4min) 

• 1. Read the notes in #016A, then do G U E with the warm-up (we'll do S S together)

  2. A baseball is popped straight up in the air and has a hang-time of 6.25s. Determine the max height (ymax). 

  3. Hint: the time to max height is 1/2 the total hang time

CLASSWORK

1. #016A: Hangtime and Max Height

    - Notes:

        - Ymax is the maximum height, and is achieved 1/2 way through the flight of the

        projectile

        - Ymax occurs at 1/2 the total flight time (often called "hang-time")

        - At Ymax, the y velocity is zero. You can use this as your initial velocity, and

        then treat the problem like a free-fall problem

    - Practice:

    - A football is kicked and reached ymax at 2.0s. How high is ymax?

At Home Learning (HW) 

**Tomorrow is daughter's birthday, and my wife is sick, so I'll be home.** 

1. #016C: Wednesday you will work on your pre-lab as we build towards our ramp/cup/ball bearing challenge this Thursday/Friday.
