Speed
The distance an object travels per unit of time
instantaneous speed
speed at a specific instant in time
Velocity
the speed and direction of a moving object
average speed
total distance divided by total time
Motion
An object's change in position relative to a reference point.
constant speed
the rate of change of position in which the same distance is traveled each second
meter
The basic SI unit of length
Acceleration
a measure of the change in velocity during a period of time
3 ways to accelerate
speed up, slow down, change direction
Formula for speed
distance/time
An object is in ( )when it's distance from a(n)
( ) is changing.
Motion, Reference point
An object at rest is not moving so its speed is...
Zero
On a speed-time graph, a(n) ( ) speed is shown by a line going upward from the left.
Increasing
On a speed-time graph, a(n) ( ) speed is shown by a line going downward and to the right.
Decreasing
On a speed-time graph, a(n) ( ) speed is represented by a horizontal line.
