Graph A
100
What is acceleration measured in?
m/s2
100
What is the formula for solving acceleration?
(Vf-Vi)/t

How far does a mouse scurry if it moves with a velocity of 5 m/s for 14 seconds?
70 meters
200
How far does the person move in 16s?
60 meters
(starts at the 20 meter line so 80-20 = 60)
200
How is acceleration represented on a distance x time graph?
A curved line
200
A cyclist increases her speed from 10 m/s to 22 m/s in 4 seconds. What is her acceleration?
3 m/s2
300
What is velocity measured in?
meters per second (m/s)
300
How long would it take a bird to fly 350 meters if it is traveling at a velocity of 14 m/s?
25 seconds
300
Which line has the greatest slope?
Line A
300
What is the difference between velocity and acceleration?
Acceleration is a change in velocity.

A train moving at 15 m/s comes to a complete stop in 10 seconds. What is the acceleration (deceleration) of the train?
-1.5 m/s2
500
What is the difference between speed and velocity?
Velocity includes direction.

A delivery van travels 18 kilometers in .5 hours. What is the velocity in meters per second?
10 m/s
(18 km --> 18000 m)
(.5 h --> 1800 s)
(18000/1800 = 10)

What does it mean when the Y intercept of one runner is higher than the person they are running against?
They have a head start.
500
What are the 3 types of acceleration?
Speed up (+)
Slow down (-)
Change in direction
