It's the Units for Me
m/s
speed
What is the formula for speed
distance over time
What is the formula for velocity?
distance over time with a direction
What is the formula for acceleration?
v2-v1
t
motion
m
distance
How is speed different from velocity?
velocity has direction
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
If we say the acceleration is negative, is it decreasing or increasing?
decreasing
The space between two objects?
Distance
seconds
time
What is the average speed of a cow that walks east 60 meters in 90 seconds? (don't forget units)
0.66 m/s
Distance = 20 meters Time = 4 minutes Direction = south What is the velocity of this object?
5 m/s south
V1 = 50 m/s south V2 = 60 m/s south Time to change velocity = 5 seconds What is the acceleration of this object?
2 m/s2 south
how fast something moves
speed
m/s north
velocity
A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled? (d=s x t)
40 meters
An object travels 25 meters in 2 seconds west. What is it's velocity?
12.5 m/s west
If we say the acceleration is positive, is it decreasing or increasing?
Speed + Direction is called?
Velocity
m/s2
acceleration
What is the speed of an object moving east for 6 seconds at 105.3 m/s?
105.3 m/s
A pink alien moved south in it's spacecraft 2000 m at a rate of 20 m/s. How much time did it take him to do this in seconds? (t=d/v)
100 s
Charlie
Change in speed or direction.
