Moving right along
This is how far the object has moved
What is distance
________________ is the distance an object travels per unit of time.
Speed
The distance and direction of an object's change in position from the starting point.
Dispacement
________________ is a change in an object's position.
Motion
The speed of an object ______________ if the acceleration is in the same direction as the velocity.
increases
This is the speed at a given point in time
What is Instantaneous speed
A _______________ ___________ is needed to determine the position of an object.
Reference point
This includes the speed of the object and the direction of its motion.
Velocity
On a distance-time graph ___ is on the x-axis and ___________ is on the y-axis.
time; distance
If an object is moving in a straight line, the size of the change in velocity equals the final speed minus the __________ speed.
initial
Acceleration toward the center of a curved or circular path is called _____________ ________________.
Centripetal Acceleration
A _______________ ___ ______________ is a coordinate system in which the positions of object can be measured.

slope
If something never varies or changes over time it is said to be _________________
constant
