Speed
the distance an object moves over a period of time
What is speed?
speed and direction
What is velocity?
the measure of change in velocity over time
What is acceleration?
The equation for velocity (speed) is
What is v = d/t?
units for velocity
What is m/s?
the speed at a specific moment in time
What is instantaneous speed?
The velocity of an object can be represented by this symbol
What is an arrow?
Like velocity, acceleration can be represented by an
What is arrow?
The equation for acceleration is
a = v2 - v1/t
units for acceleration
What is m/s2?
the rate of position in which the same distance is traveled at each second
What is constant speed?
The length of a velocity arrow indicates this
What is speed?
When velocity increases the acceleration arrow points in the _________ direction as the velocity arrow.
What is same?
the x-axis of a speed time graph represents _____
What is time?
distance and direction from a reference point
What is position?
total distance divided by total time
What is average speed?
If an object is traveling from east to west, which direction would the arrow point to show its velocity?
East to west
When velocity is decreasing, the acceleration arrow points in the ________ direction as the velocity arrow.
What is opposite?
The y-axis of a distance-time graph represents ____.
What is distance?
vertical axis
What is y-axis?
this type of graph can be used to show distance over a period of time, average speeds can be calculated using this graph
What is a distance-time graph?
This changes when speed changes, when direction changes and/or when both change.
What is velocity?
If an object is slowing down, it is accelerating. True or False
What is true?

What is 10 m/s?
horizontal axis
What is x-axis?
