what is the difference between speed and velocity?
velocity has the speed of the object AND its direction, while speed is just how fast an object moves.
100
what is this velocity vs. time graph showing?
constant speed
100
how do you calculate average speed?
average speed= distance traveled/time of travel
100
how do you calculate speed?
speed= distance/time
100
what is this distance graph showing? 
constant speed
200
what is acceleration?
acceleration is an object changing motion ie. speeding up, slowing down, etc.
200
what is the object doing on the graph? 
the object is moving away from the reference point at a constant speed before turning around and heading back to the reference at a constant speed.
200
what type of graph is this?
a velocity vs. time graph or speed vs. time graph
200
what are the two time graphs and what do they represent?
velocity (speed) vs. time graph: shows how fast an object moves over time
distance (position) vs. time graph: shows how far an object moves over time
200
choose between speed or velocity;
megan is traveling at 60 km/h in her vehicle.
speed
300
what is average speed?
the speed of an object with its acceleration and deceleration.
300
what is the formula for acceleration?
m/s2
300
Which two letters show constant speed?
1. a and c
2. b and c
3. b and d
1. a and c

A person walked 10 meters in 100 seconds, what is their average speed?
0.1 m/s
300
velocity, speed, or acceleration?
nathan is walking 9 m/s towards his house, which is north of where he is now.
velocity
400
is there a difference between a position time graph and a distance time graph?
no, the two are the same (interchangeable)
400
which story makes the most sense with the graph?
a. jon was running at a slow constant pace towards the library, before sprinting, then stopping to go into the library; once checking out his books, he sprints the rest of the way home.
b. mark starts off stopped at the chicken store, before sprinting to the cow store. mark stops again, but not before quickly leaving the cow store and slowly walking back to the store he was originally in.
a
400
which graph shows constant speed? (remember, this is a velocity vs. time graph)
1

3
1.
400
where is the object stopped? (velocity vs. time graph)
a. a and b
b. d and e
c. b and c
d. a, b, c, d, e, and f
b. d and e
400
if ethan is red, martin is black, and joe is red, who's constant speed is the fastest? 
martin is going at a faster constant speed than joe and ethan
500
what is this distance vs. time graph showing us? 
acceleration!!

which of these formulas for time are correct?
a. t=s/d
b. t=d/s
c. y=kx
d. d=t/s
b.
500
true or false; speed vs. time graphs aren't the same as velocity vs. time graphs
false
