Speed Graphs

Multiple Choice

How do you write an ordered pair?

• (X,X)

• (Y,X)

• (X,Y)

• (X, Y, Z)

Multiple Choice

What letter is located at (8, 5)?

• A

• B

• C

• D

Speed – Time Graphs

• Shows how  speed changes over time

• X axis = TIME

• Y axis = SPEED

Drag and Drop

In a speed graph distance is represented along the ​

Placeholder

and time is represented along the ​

Placeholder

.

Drag these tiles and drop them in the correct blank above

y-axis

x-axis

Multiple Choice

Which runner won the race?

• A

• B

• C

Speeding Up

• The line on a speed – time graph is CLOSER to the x-axis in the BEGINNING of the time period when it has a LOWER speed

• The line slants  UPWARD toward the right side of the graph as the speed INCREASES     

  
  

Multiple Choice

• Speeding Up

• Slowing Down

Multiple Choice

What are these graphs showing?

• Increasing speed

• Constant Speed

• Object at Rest

• Decreasing Speed

Multiple Choice

Who's Faster?

• Barkus

• Arctica

Constant Speed

• The line will be HORIZONTAL

• The further the line is from the X-AXIS the FASTER it is moving.

Constant Speed

• Distance increases at a steady rate

• Object's speed does not change, but it is not zero

Multiple Choice

What does this graph represent?

• Constant speed

• Acceleration

• Not moving

Multiple Choice

What does this graph represent?

• Constant Speed

• Acceleration

• Decceleration

• Not moving

Object at Rest

• The speed is zero and does

   not change

• Horizontal line (like a

  distance – time graph  y = 0

Multiple Choice

How many times does this object STOP moving?

• None

• Once

• Twice

• Three times

Slowing Down (Negative Acceleration)

• When initially starting to slow down the  point representing speed is FAR from the x-axis.

• When the line touches the x-axis, the speed is ZERO and the object

  stopped.

• The line on a speed-time graph slopes downward to the right. 

Decreasing Speed

• As the distance increases the rate of increase gets smaller over time

• The speed of the object decreases at a steady rate over time

Multiple Choice

What are these graphs showing?

• Increasing Speed

• Constant Speed

• Decreasing speed

• Object at rest

Multiple Choice

• Speeding Up

• Slowing Down

Multiple Choice

What is a reasonable story for this graph?

• The airplane is stopped at the gate

• The boat is moving at a constant speed

• A car slows down to avoid an accident

REVIEW

Answer the following question

The remainder of the lesson is review. You may also need to use the speed or velocity equation. Tomorrow there will be a quiz over all this information for the end of the quarter.

distance/time=speed

displacement (distance)/time=velocity (speed + direction)
