10/05/2015ACTIVITY #13 Introduction to Describing Motion

1.Go get your textbook2.Read page 11 – 15 silently.3.ACTIVITY #13: Define all chapter 1 vocabulary.

The 10 words highlighted in yellow. They are on pages 11 – 29 (Reference point, position, motion, displacement, speed, constant speed, instantaneous speed, average speed, velocity, and acceleration.) See next slide for definitions

4.Start the crossword puzzle on page 27. Use your vocabulary definitions to help you complete this crossword. When completed, this will be turned in for credit.

MOTION Vocabulary found on page 11 - 291.REFERENCE POINT: The starting point you choose to describe the

location, or position, of an object.2. POSITION: An object’s distance and direction from a reference point.3.MOTION: The process of changing position.4.DISPLACEMENT: The difference between the initial (first) position and

the final position of an object.5.SPEED: A measure of the distance an object travels per unit of time.6.CONSTANT SPEED: The rate of change of position in which the same

distance is traveled each second.7.INSTANTANEOUS SPEED: Speed at a specific instant in time.8.AVERAGE SPEED: The total distance traveled divided by the total

time taken to travel that distance.9.VELOCITY: The speed and the direction of a moving object.10.ACCELERATION: A measure of the change in velocity during a period

of time.

10/6/2015 Changes in VelocityEQ: What does a speed-time graph indicate about an object’s motion?

Write and answer your bellringer on this weeks bellringer page in your INB.

•Go and get your textbook.

•10/6 BELLRINGER: How can you describe an objects position? •Answer: Position is an object’s distance and

direction from a reference point.•See page 11

10/6/15 Changes in Velocity -ContinuedCLASSWORKActivity #14 Speed, Time, and Distance GraphsGo to page 32-34 in your textbook. Copy the graphs pictured on those pages (figures 14, 15, 16, 17, and 18) The distance-time graphs are the yellow boxes with red lines. Make sure to add the labels shown on each graph.Add the descriptions written below the graphs.

10/7/2015 BELLRINGER

Why is it important to have a reference point?Answer: Without a reference point you cannot describe the location, or position, of an object.

See page 11 - 13

10/ 6 and 7 /2015 Activity #15 Describing Motion / Graphic

Organizer1.Go to p 37 in your textbook.2.Copy and complete the graphic

organizer using the vocabulary list/definitions we completed on 10/5 Activity #13: Motion Vocabulary p 11-29

3.When completed, add the organizer to your INB as Activity #15: Describing Motion/Graphic Organizer.

10/7 ACTIVITY #16: Four Types of Speed - Time Graphs p32-34(2nd/3rd/4th/and 6th Period Tree Map) ( 5th Period: Four Panel Foldable)Types of Speed - Time Graphs

Object at Rest Constant Speed Speeding Up Slowing DownAN OBJECT AT RESTIS NOT MOVING. ITSSPEED IS NOT CHANGING OVER TIME.

ITS SPEED IS ALWAYSZERO.

THE SPEED-TIME GRAPH FOR AN OBJECT AT REST IS A HORIZONTAL LINE.(figure 14 on page 32)

AN OBJECT GOINGAT A CONSTANT SPEEDIS NOT CHANGING OVERTIME.

THE SPEED IS ALWAYSTHE SAME.

FOR AN OBJECT MOVING AT A CONSTANT SPEED,THE SPEED-TIME GRAPHIS A HORIZONTAL LINE.(figure 15 on page 33)

AN OBJECT THAT IS SPEEDING UP IS INCREASING SPEED OVER TIME.

THE LINE ON THESPEED-TIME GRAPHIS CLOSER TO THE x-axis AT THE BEGINNING OF THE TIME PERIOD WHENTHE SPEED IS LOWER.IT SLANTS UPWARD TOWARD THE RIGHT SIDE OF THE GRAPH ASSPEED INCREASES. (figure 16 on page 33)

AN OBJECT THAT IS SLOWING DOWNIS DECREASING SPEED OVER TIME.

AS SPEED DECREASESTHE POINTS REPRE-SENTING ITS SPEED ARECLOSER TO THE x-axis, THE SPEED IS ZERO WHEN THE OBJECT STOPS.(figure 17 on page 34)

OBJECT AT REST• AN OBJECT AT REST IS NOT MOVING.

• ITS SPEED IS NOT CHANGING OVER TIME.

• ITS SPEED IS ALWAYS ZERO.

• THE SPEED-TIME GRAPH FOR AN OBJECT AT REST IS A HORIZONTAL LINE.

• (figure 14 on page 32 on the right side)

CONSTANT SPEED• AN OBJECT GOING AT A CONSTANT SPEED IS

NOT CHANGING SPEED OVER TIME.

• THE SPEED IS ALWAYS THE SAME.

• FOR AN OBJECT MOVING AT A CONSTANT SPEED,THE SPEED-TIME GRAPH IS A HORIZONTAL LINE.

• (figure 15 on page 33 on the right side)

SPEEDING UP• AN OBJECT THAT IS SPEEDING UP IS

INCREASING SPEED OVER TIME.

• THE LINE ON THE SPEED-TIME GRAPH IS CLOSER TO THE x-axis AT THE BEGINNING OF THE TIME PERIOD WHEN THE SPEED IS LOWER. IT SLANTS UPWARD TOWARD THE RIGHT SIDE OF THE GRAPH AS SPEED INCREASES.

• (figure 16 on page 33 on the right side)

SLOWING DOWN

• AN OBJECT THAT IS SLOWING DOWN IS DECREASING SPEED OVER TIME.

• AS SPEED DECREASES, THE POINTS REPRESENTING ITS SPEED ARE CLOSER TO THE x-axis, THE SPEED IS ZERO WHEN THE OBJECT STOPS.

• (figure 17 on page 34 on the right side)

10/8 BELLRINGERDescribing Position in Two Dimensions. What does this mean?See page 14Answer: • First, choose a reference point. (from Clermont Middle)• Next, specify a reference direction (north, south…) • Then, determine the distance along each reference

direction. ( 2 miles east and five miles north of Clermont Middle)

10/8 ACTIVITY #17 Ways an Object can Accelerate

EQ: What is the difference between constant and changing speed? Constant Speed Changing Speed Traveling the same (or constant) distance per second.

Traveling different (or changing) distances per second.

The relationship betweenACCELERATION and VELOCITY (see

p 29-30)How does an object accelerate?Answer: An object accelerates when velocity changes.

How does velocity change?Answer: Velocity changes when speed, direction, or both speed and direction change.

10/8 ACTIVITY #17 - continuedWays an Object can Accelerate

• FRONT OF NEXT AVAILABLE PAGE:• Title the page – “Constant and Changing Speed”• Cut out figure 6 on page 20. • Glue figure 6 on your next available INB page.

• BACK OF SAME PAGE:• Title this backside of the page – “Ways an Object can

Accelerate”• Cut out figure 13 on page 30.• Glue figure 13 on this side of the same page.

10/8 How can velocity change? EQ: What are three ways velocity can change? ANSWER: Velocity changes when - 1.Speed changes2.Direction changesor 3. Both speed and direction change

I AM OBJECT AT REST:

Not moving

I AM AN OBJECT THAT IS SLOWING DOWN:

Negative acceleration or deceleration / decreasing

speed

I AM AN OBJECT THAT IS SPEEDING

UP:Positive acceleration / increasing speed

I AM AN OBJECT THAT IS GOING AT

A CONSTANT SPEED:

Speed stays the same but object is in

motion.

How fast is that

object going?
