Speed Flashcards
the rate of change in position of a moving object
speed
You measure speed from a _________.
Reference Point
speed = distance/time
speed equation
s = d/t
Speed Equation
the distance an object travels per unit of time
speed
any change over time
rate
If the speed you calculate is the same regardless of the interval you choose
constant speed
If the car neither slows down nor speeds up
constant speed
the total distance traveled divided by the total time of travel
average speed
it can be calculated using the relationships between speed, distance, and time.
Average speed
the graphs line is in a straight line
it is a constant speed
the slope of a line =
the objects speed
the graph changes slopes
the speed changes rate over time
if the object has stopped moving
the graph is horizontal
zero slope
an object at rest
