Force and Motion Unit 6

What does the slope of each line on the graph tell you?

• The speed of each runner
• The acceleration of each runner

Which runner complete the 100 meter race in the least amount of time?

• Albert
• Bob
• Charlie

Which runner started out the fastest?

• Albert
• Bob
• Charlie

What is happening between 9am and 11am?

• The cyclist is traveling up a hill
• The cyclists is speeding up
• The cyclists is traveling at a constant speed
• The cyclist is slowing down

What do you think the cyclist is doing between 11am and 1pm?

• The cyclist has stopped for lunch
• The cyclists is riding at a constant speed on flat ground
• The cyclist is practicing sprints
• The cyclist is riding up a hill

What is the total distance covered by 2 pm?

• 40 miles
• 30 miles
• 60 miles
• 10 miles

The 2 objects have the same average speed over the 7 seconds. Why?

• Both objects traveled the same distance in the same amount of time.

• The graph for Object B is steeper at the end of the time.

• Object B has sections of zero speed while Object A is never stopped

• The final position on the graph for Object A is much greater.

What is happening in section C?

• going down a hill

• speed is increasing

• speed is decreasing

What is occurring at E?

• It is traveling at a constant speed

• there is no change in motion

At which position is the object accelerating the fastest?

• c

• k

• neither because they are slowing down, which isn't acceleration
