What is the formula for speed?
Speed = Distance / Time
100
What is the formula for velocity?
Velocity = Distance / Time with a direction
100
What is the formula for acceleration?
Acceleration = Final Velocity - Initial Velocity / change in time with a direction
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/hr squared, south a possible unit for?

Acceleration

200

What goes on the x axis?

time (independent variable)

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 minutes 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 (linear) line indicate about a moving object?
It's moving at a constant speed

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? 

decrease in velocity over time or slowing down.

400
For what formula would decimeters/hour east be a possible unit?
velocity
400

What is the difference between independent and dependent variable?

Independent variable can be on its own and dependent variables relies on the independent variable.

Jon and his dog are out for a walk and are walking at the same velocity. At the same time, Jon's dog speeds up, and Jon tries to slow down. Jon's dog is the only one demonstrating acceleration.  

Is this statement true or false?

False, they are both demonstrating acceleration.

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 horizontal line in a velocity graph indicate?

The object is at rest (no movement)
