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 does the slope of the line in a distance vs time graph tell us?

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 ... 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 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/s2, south

300
Which of our formulas must have a direction in order to be complete?
velocity
300

What does a horizontal line in a distance vs time graph indicate?

The object is not moving.

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?

slowing down or a decrease in velocity over time

400

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

velocity

400

What does the slope of a line in a velocity vs time graph tell us?

The acceleration of the object.

500

1.82 hours

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

A bike slows from 6 m/s2 to a stop in 9 seconds. What is the bikes acceleration?

-99.3 m/s2

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 on a speed vs time graph indicate?

The object is traveling at a constant velocity (not accelerating).
