The total distance traveled divided by the total time
Instataneous speed
The rate of an object when it is moving at a given time
Velocity
Definition
The Speed and Direction of the objects movement
Important for
Airplane pilots
To not collide with other aircrafts
Landing the plane
Citizens
In case of a Twister (hurricane, Tornado etc.)
Reference Point
An object that determines if you are in motion or
not
Tree
Sign
Pole
Building
Sometimes it is hard to determine if you're moving if your
reference point is a moving object too. For example when
your reference pint is another moving object it is difficult to
determine if you are in motion if the object is also in motion
Acceleration
Definition
The rate of which velocity changes
Increasing Speed
A train that moves from a stopped position
A volleyball that is served from the server
Decreasing Speed:
aka Deceleration or
negative acceleration
When an object slows down
The volleyball decelerates when it is caught
Changing Direction
When the object curves, goes left or right.
Formula
The Initial speed subtracted by The final speed divided by time (Final speed - Initial speed/ Time
Graphing Acceleration
Time as your x axis and speed as your y axis
If the graph is pointing upwards
(steep) it means the speen is
increasing
If the graph is a straight line it
means the acceleration was at a
constant speed
Time as your x axis and distance as your y axis
if the graph shows a curved line it means the object is
accelerating
means that you traveled a greater
distance during the third than you
did in the first and second
Graphing motion
Formula for slope
rise over run
plot points when the x axis is time and y axis is y
these points turn into a slope
slope determines how fast a
variable changes compared to
the other points on the graph
