Definition
 change in position over timecan be described and predictedmeasured relative to the observer
Term
 Reference point
Definition
 a location in which you compare other locations
Term
 Distance is measured in:
Definition
 Centimeters, meters, and kilometers
Term
 Speed
Definition
 The rate of change in position of an objectratio between two different quantities
Term
 Constant speed
Definition
 when the speed does not change
Term
 Average Speed
Definition
 Total distance divided by the total time traveled
Term
 Formula for speed
Definition
 Distance divided by time equals speed
Term
 Velocity
Definition
 describes both the speed and direction of the object
Term
 Acceleration
Definition
 rate of change of velocityIf veloicty does not change their is no accelerationpositive when speed is increasingnegetive when speed is decreasing
Term
 formula for acceleration
Definition
 Final velocity-initail velocity divided by time
Term
 Centrifugal
Definition
 acceleration of an object moving in a circular path away from the center of the circle
Term
 Centripedal
Definition
 Acceleration of an object moving towards the center of the circle
Term
 Velocity vs. Time Graphs
Definition
 A rising like on the graph indicates that acceleration is positiesA falling line on the graph indicates acceleration is negetiveA flat line on the graph indicates NO acceleration
