A curved line demonstrates acceleration.
The steepness of a curve shows the
varying distances at given times.
Speed vs. Time
Acceleration is the
slope of this line,
Calculating
To calculate acceleration, subtract the
initial speed from the final speed and
put that over the total time.
Forms of Acceleration
Increasing Speed
Decreasing Speed
Changing Direction
Reference Points
Relative Motion
If the reference point to an
object is in motion, it makes the
object itself, appear to be moving
in relation to the moving object.
Used to determine if an
object is moving by seeing
where the object is in
relation to the reference
point at any given time.
Measuring Distance
Distance is measured in meters a
majority of the time. The standard
system of measurement is from
the International System of Units.
Graphing
Slope
Calculating Slopes
Rise/Run
Different Slopes
Not all objects stay at a single
constant speed. Some graphs are
separated into segments to
display the varying speeds. Each of
these segments have different
slopes. This way, you can tell how
the speed of an object changes,
Distance-vs-Time
A point on this line would show
the distance travelled at a set
time,
Speed
Average Speed
To calculate the average seed of
an object, divide the total distance
by the total amount of time.
Speed Equation
By putting distance/time,
you can calculate the
speed of an object.
Instantaneous Speed
Instantaneous speed is the
rate that an object is
moving at a specific time.
