motion-5th period

A distance vs. time graph shows an object's

• frame of reference
• speed
• acceleration
• favorite food

LT2: I want to find the average speed of a triathlon race. What steps would I take? 

• add up total distance, add up total time, divide total distance by total time
• add up total distance, add up total speed, divide distance by speed
• Add up total time and subtract total distance

LT2: Grayson walks 5 meters in 5 seconds. What is his average speed? 

• 25 m/sec
• 1 m/sec
• 5 m/sec
• .25 m/sec

LT4: The graph shows Ashley riding her bike to Maria's house. 
What is occurring from point A to point B?

• they are traveling at a constant speed
• they are decreasing in speed
• they stopped to take a break

LT4: The graph shows Ashley riding her bike to Maria's house. 
What was occurring from point B to point C?

• She was increasing her speed.
• She stopped for 4 minutes
• She was decreasing in speed

LT5: What is velocity?

• Time + Distance
• Speed in a given direction
• A fast dinosaur
• The direction a storm is moving

LT5: The rate at which velocity CHANGES is: 

• acceleration
• speed
• direction
• physics

The graph represents

• no motion
• Constant velocity
• Acceleration
• negative acceleration

The graph represents

• no motion
• constant velocity
• acceleration
• negative acceleration

The graph respresents

• No motion
• Constant Velocity
• Acceleration
• Deceleration
