acceleration of the object
distance the object has traveled
velocity of the object
To determine the acceleration rate of an object, you must calculate the change in speed during each unit of
velocity
time
motion
deceleration
If speed is measured in kilometers per hour and time is measured in hours, the unit of acceleration is
hours
kilometers per hour
kilometers per hour per hour
kilometers
Average speed is
equivalent to velocity
the rate at which an object is moving at a given instant
the rate at which a slope changes
the total distance traveled divided by the total time
If you know the distance an object has traveled in a certain amount of time, you can determine
the size of the object
the speed of the object
the location of the object
