Questions about Distance vs. Time Graphs
100

What is the formula for speed?

Speed = Distance / Time

s=d/t

100

What is the formula for velocity?

Velocity = Displacement/ Time with a direction

v = ∆x/t

100

What is the formula for acceleration?

Acceleration = Final Velocity - Initial Velocity / change in time 

a=(vf-vi)/t 

100
What formula is m/s an example unit?
speed or average speed
100
What can we find with a distance vs time graph?
speed of an object
200
How is speed different from velocity?
velocity needs a direction
200
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
200

What are three ways we can tell if something is accelerating?

speeding up, slowing down, changing direction

200

What is km/hr2, south.. a possible unit for?

Acceleration

200
What goes on the x axis?
time
300
What is the average speed of a cow that walks east 60 meters in 90 seconds? (Remember, the units must be m/s or km/hr)
.7 m/s
300

Distance = 20 meters Time = 4 seconds Direction = south What is the velocity of this object?

5 m/s south

300
Final Velocity = 50 m/s south Initial Velocity = 60 m/s south Time to change velocity = 5 seconds What is the acceleration of this object?
-2 m/s squared, south
300
Which of our formulas must have a direction in order to be complete?
velocity
300

What does a distance vs time graph with a straight line (linear / or \) indicate about a moving object? 

It's moving at a constant speed

400

A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled?

40 meters

400
An object travels 25 meters in 2 seconds east. What is it's velocity?
12.5 m/s east (must include direction!)
400

How would you describe negative acceleration? You must use the word "velocity".

decrease in velocity over time

400

For what formula would kilometers/hour east be a possible unit?

velocity

400
What does a horizontal line in a velocity graph indicate?
The object is at rest (no movement)
500
What is the speed of an object moving east for 6 seconds at 105.3 m/s?
105.3 m/s
500
A pink alien moved south in it's spacecraft 2 km at a rate of 20 m/s. How much time did it take him to do this in seconds?
100s
500

How would you describe the acceleration of this object? - 14 m/s squared, east

negative acceleration, decrease in 14 m/s every second, the object is slowing down

500
What formula would we use if we wanted to find out how an object's velocity changed within a certain period of time?
What is Acceleration
500

What does a negative sloped line on a distance vs time graph indicate?

The object is traveling back towards the starting point.
