What formula would this go to?
Graphing
100
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 goes on the x-axis of a distance vs time graph?
Time
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
A graph that has time in seconds on the x-axis and distance in miles on the y-axis will give you a speed with what unit?
Miles per second (mi/s)
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 graph below shows acceleration?
D

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 decimeters/hour east be a possible unit?
velocity
400
What is the speed at 20 s for this graph?
-0.467 m/s
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
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
Describe what's happening in this graph in terms of someone running a 200m race.
The person starts out accelerating at a constant rate for 10 seconds, then runs at a steady speed for 10 seconds, then accelerates again for 10 seconds, then decelerates for the remainder of the race.
