100

What is the equation for speed?

Speed = Distance / Time

100

What is the equation for velocity?

Velocity = Distance / Time with a direction

100

What is the equation for acceleration?

Acceleration = Final Velocity - Initial Velocity / change in time with a direction

100

What equation is m/s an example unit?

speed or average speed

100

What can we find with a distance vs time graph?

speed/velocity 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 kind of line represents the object is moving backwards in a distance vs time graph?

Downwards sloping line

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 equation 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
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

There is a difference between distance and displacement. Which equation does each one go to?

distance > speed, displacement > velocity

400

What does a horizontal line in a velocity vs time 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/s2, east

negative acceleration, decrease in 14 m/s every second

500

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

acceleration

500

How do you find the total distance traveled in a distance vs time graph?

Add up all the line segments
